Chuckie Eggs the remake for PC -- 2007 (direct link)

This is a free, open source remake of Chuckie Egg written in assembler and Borland Pascal 7.0, complete with level editor. The author references the Hungarian/English commented code as illustrations of VGA programming, especially the MODEX video modes (double-buffered page flipping). The game runs on PCs as old as a 486 through to Window XP, though page flipping might not be perfect or too fast in the latter, so the use of DOSBox is recommended.

The game itself is loosely based on the the SPECTRUM 48K release with the same keys, though the graphics are more colourful and the screen layout is significantly different - with the status bar moved to the bottom of the screen. The first three levels are reasonably close to the usual layouts, but the rest of the sixteen screens are more original including ropes to compliment the ladders. Harry's jumping is much less responsive than one would hope and, unforgiveably, the mother duck is missing!

Further Adventures of Farmer Giles! Story so far... Farmer Giles had his prize winning hens stolen by his rival, Farmer Hopkirk. Giles sets out to retrieve as many of his eggs as possible and teach Hopkirk a lesson he'll never forget! This is a great remake with colourful graphics and nice gameplay. A worthy prequel to John's later Chuckie Egg remake.

UPDATE: The Chuckie Egg for Windows website is currently offline. Whilst we eagerly await it's return, we have mirrored the complete Windows installer and source code from the latest version, 1.1. Executable and source for 1.04 also available.

DirectX Chuckie Egg Now! button link DirectX Chuckie Egg DirectX Chuckie Egg Level Editor v1.2

Based on the BBC 32K release, this is the oldest and most featureful remake. The physics of Hen House Harry's movements are almost, but not quite, identical to the original release. This unofficial port includes the Variable Extended Jump option from the popular upgrade of the BBC 32K original, CHUKEE from BIT TWIDDLERS, and also features user-definable graphics. The source code and a Level Eggitor are available for download, the latter allowing users to design their own customised levels - other example levels available include the set of eight custom levels that were originally supplied with CHUKEE. If you do not already have it installed, the Level Eggitor will require the Microsoft Visual Basic 4.0 32-bit run-time engine. Hitm4n of Retro Remakes is one of those who has made use of the Level Eggitor, in order to create Hitman Egg, a set of six new levels bundled with custom graphics. Kevin Adams has also customised the graphics to produce Cash Dash.

Mike Elson reveals that the essential tool for creating this Borland C++ 4.52 remake was the now-defunct commercial BBC micro emulator pcBBC, which was used to generate screenshots from the original game to get the look right. "To work out the jump patterns I ran the emulator in 'slow motion' mode and took a screenshot after each re-draw... many of the moves that were possible in the original are recreated faithfully, but there were always things like bouncing off platforms, which I never got right. I got the samples by playing Chuckie on a real BBC with wires running from its internal speaker to the sound card of a PC, and recording sections of gameplay to edit down into raw sounds."

GJ Chucky Egg -- 2000

This remake contains 36 levels with password access, and is available as a downloadable shareware demo. It has all the expected Chuckie Egg objects with a few additions like extra lives, killer plants, fire and spikes. The website includes the option to play online (requires Clickteam's Vitalize! Active X plugin).

Chuckie Egg: The Next Batch -- 2003
(old site now unavailable - archived at The Internet Archive Wayback Machine)

This remake updates Chuckie Egg to take more advantage of the capabilities of modern machines. Not an exact clone, being supplied with all-new graphics, levels and features, this is a popular Blitz Basic interpretation of the classic original. There is also a promise of themed add-on packs with more new graphics and levels being available in the near future.

EggStatic -- 2005 (commercial release, free demo available with 8 levels & 8 training levels)

A great, new OpenGL / DirectX 8 release that requires a 32MB 3D videocard, written using Garage Games' Torque 2D engine - track the game's development in the community forum. This modern remake builds on the BBC 32K release and was designed to add many new features without taking anything away from the original gameplay. Amongst the new features, there are bonus levels, a new two player co-operative mode (full version only), up to 75 minutes of a techno soundtrack, a demo record facility, a save function between rounds and new level features including magic eggs, slippery ice floors and trampolines for Harry to cope with. Longevity has been addressed, in order to make the full release worthy of the asking price, with the inclusion of an in-game level editor and a " moddable" engine so that custom campaigns, levels and graphics can be added.

This remake is certainly not an identical clone to the original but the bright, colourful high resolution graphics have been drawn in a large pixel, blocky-style to retain the authentic look of the original, whilst making it appealing to the modern player's eye. Small touches like Harry's materialisation when he begins a level, the dust he kicks up as he runs, the display of the points value as eggs & seed are collected and how his feet stop moving mid-jump if the direction key is released, all make nice eye-candy without interfering with the gameplay too much - though it is a bit disconcerting to see Harry climb behind the ladders, instead of in front. The sound effects are quite different from the original, with Harry padding along the levels rather more quietly than the original and the Cassowaries (previously known as hens) making an incongruous squawking sound if Harry touches them. Thankfully, the sound options allow the volume to be adjusted and the removal of the techno soundtrack which can grate after a while, if you're not a fan of the genre. There are 125 levels in the full version (with the promise of 50-60 more coming soon, in a campaign to be provided with the next version upgrade), though none are direct copies of the level layouts in the original. Possibly the biggest change for players used to the original releases will be the new control system which combines the Up and Jump keys. Whilst this may well make things easier for new players, it is quite disconcerting for the CE Professional. The final thing worthy of note is that this is the first remake to include the features that, according to his interview, Nigel Alderton had hoped to include in the original Spectrum release but was forced to drop, citing time pressures, including missing ladders and platforms to disrupt a player's patterns later in the game and the popularly mis-remembered second hawk (a duck in the original), that has a different speed and acceleration to the first.

Chuckie Egg Remake -- 2006/2013 (WIP thread)

This is a great version of Chuckie Egg for Easter '06. Based on the SPECTRUM 48K release, this remake comes with pixel perfect in-game graphics, faithful to the original. All of the graphics, sounds and level designs are fully customisable - the package ships with a gorgeous set of re-worked graphics and six new level designs, alongside the originals. New features over and above the Spectrum version include a built-in level editor which isn't fixed to a dozen eggs & five hens and also support for lifts which travel down, as well as up. This last, unique, feature allows cunning level designs which add a whole new dimension to CE - a great addition.

UPDATE: Rob updated his release in 2013, and it is now available for both Android and HTML5, alongside a refreshed Windows version.

Chuckie Egg Returns -- 2008

Available as a Windows executable or playable as a Java applet through the website. The source code for the Java applet update is not provided, but the FreeBASIC v0.18 source of the initial native Windows version is available for download. It plays quite slowly, the collision detection isn't great and the graphics aren't very polished. Plenty of extra neat little features have been built into the display, though, including a complete map of the level - only part of the level is viewable on the screen. There is a Chuckie Egg Returns (0.3) discussion forum topic at the FreeBASIC Games Directory.

Native Chuckie Egg for Windows -- 2009

This tiny (19kb) binary is Mark's Windows port of Michael Foot's accurate version of Chuckie Egg for RISC OS. Following his DHTML and SDL conversions, this final version was designed from the start to be the first 100% native port of the BBC Micro release of Chuckie Egg to Windows, whilst trying to remain as close to the size of the original BBC binary as possible. Whilst the sound doesn't quite capture the original exactly, there's really not a lot to complain about here. It doesn't have any of the GUI niceties of Mike Webb's long-standing, popular release, but that wasn't the intention here. What you get is pure Chuckie Egg in a window. What more could you want? GPL source code and a write-up of what it took to produce this executable? It's all here, along with a series of interesting articles.

Chuckie Egg -- 2009

This remake was created with YoYo Games' GameMaker and is available as a downloadable executable or playable over the web through YoYo Games' Instant Play browser plugin for Windows. Made as a homage to the Spectrum original, it contains 25 levels and includes the additional Mother Duck that Nigel has been quoted as wanting to have included. The game plays like some of the Flash and Shockwave remakes of Chuckie Egg, and is noticably different to the original in some respects - it is possible to jump completely over the hens, for example.

Div Chuckie Egg -- AWOL

Announced in the Div Arena Forums on 22 Feb 2002, this remake version includes two modes, Original and Enhanced. The Original mode is an exact replica of the AMSTRAD version, which the author feels is the best of the CE releases. The Enhanced mode is the same game, but with updated graphics etc. The author has claimed it looks tasty and plays pretty good too but, unfortunately, only screenshots are available because a hard drive crash has resulted in the loss of the original 8 level demo which was released to a couple of years ago. If anyone can provide a copy of this, get in touch and we'll get it back online where it belongs.

Native SDL Chuckie Egg -- 2009

This SDL port is Mark's follow-up to his online DHTML Chuckie Egg project. He has ported Michael Foot's faithful version of Chuckie Egg for RISC OS to ANSI C, filling in the gaps for non-Acorn platforms to create an incredibly accurate, modern source port based on the cross-platform SDL graphics library. Whilst we had problems with the sound on our 64-bit version of Debian Testing, that could be a local issue. Like the Windows port Mark moved on to after this, there are no GUI niceties here like those found in Mike Webb's long-standing, popular release - this is Chuckie Egg, in it's purest form. Best of all, not only is the GPL source code available for download, but Mark has spent an incredible amount of time documenting the development of the project, along with other interesting articles.

If you're interested in creating a faithful port of the original BBC release to a modern platform, start with the source code and documentation available here.

UPDATE: A compiled executable of Mark's remake is now available for the Raspberry Pi.

BBC Micro Chuckie Egg authentic clone -- 2011

This open source port began as a memory dump of the BBC 32K version. The code was reverse engineered and, after many cleanup passes, resulted in a plain C implementation that accurately implements the engine of the original game.

The sound appears to have been slightly mangled but the main gameplay remains pretty much faithfully intact. The project is, however, missing the final niceties like the initial menu and "get ready" screens, though Paul has apparently left obvious points to add them back in if someone else wants to take a crack at implementing them. After a bit more code cleanup, Paul was able to isolate the game engine from the graphics engine, allowing multiple rendering backends. This has resulted in four versions of the executable to play with - conventional SDL, ascii art, OpenGL accelerated SDL, and an experimental full 3D view.

Paul has also developed this project to run on the Pandora handheld console.
BBC Micro Chuckie Egg authentic clone Screenshot The GPL-licensed source is available from github and has been tested on Linux (x86 and ARM) and Pandora. With a bit of tweaking, the project is compilable for Windows and, in theory, anything else with SDL support should also work. Windows binaries and a source patch are available for download from our own site, courtesy of the talented and ever-helpful Phil Ashby. There is a known issue with the Windows OpenGL and 3D binaries, in that if you attempt to minimise the game window, the executable will crash. If anyone decides to take this project any further, don't forget to let us know about it!

UPDATE: Compiled executables of Paul's partial remake are now available for the Raspberry Pi too.


Chuckie Egg for RISC OS Screenshot Michael Foot's
Chuckie Egg for RISC OS -- 2001

This port runs full-screen on all versions of RISC OS from 3.xx to 4.xx and requires the 32 bit system modules. The 32-bit source code, reverse engineered from the BBC 32K release and converted to RISC OS, is available for download. This makes this version the first fully accurate remake on a completely different platform, with an identical physics engine.

The latest update, courtesy of Alan Buckley, adds support for RISC OS 5.xx and the higher resolution screen modes on the Iyonix as well as adding the option to use outline fonts for the text. This new 1.04 version will still run on older Acorn hardware as well but requires RISC OS 3.6 or above.

Dynamic HTML

DHTML Chuckie Egg Screenshot Mark Lomas'
DHTML Chuckie Egg -- 2009

Mark's goal when porting the original BBC Micro release to modern web browsers was to try and make it as close to perfectly faithful as possible, and the effort really shows. Whilst the behaviour of the hens is noticably different due to the nigh-on-impossibility of trying to replicate the random number generation of the original BBC Micro code, anyone who complains about the physics could only be described as being churlish. Mark admits it's only about 99% accurate, but you'll be hard-pushed to tell during play. Depending on your browser and system, you may experience audio lag but there is an audio diagnostics page to help you troubleshoot. This dynamic web version even includes an online Level Editor which stores your own custom levels as text in an unlimited cookie. Finally, in a true show of altruism, Mark has provided the GPL source code and also spent a significant amount of time and effort documenting the development of his online port, with particular emphasis on the algorithms devised to mimic the original, in a series of interesting articles. An awesome achievement overall, and one to be applauded.

UPDATE: Rob Edwards updated his own Chuckie Egg remake in 2013, which is now available for both Android and HTML5, alongside a refreshed Windows version.

Raspberry Pi

pbrook Chuckie Egg on Raspbian Screenshot The Raspberry Pi is a cheap, credit card sized, single-board system on a chip (SoC) computer with an ARM processor, which was designed to stimulate the teaching of computer science in UK schools. Several operating systems are in the process of being ported to the Raspberry Pi, including RISC OS, but the primary OS is Raspbian, a variant of the long-running Linux distribution, Debian. To run Chuckie Egg on a Pi, then, is not really a matter of porting the game, so much as waiting for Raspbian and/or the RISC OS port to be sufficiently developed to run the existing Linux and RISC OS ports of CE.

It didn't long take then, for forum member ukscone to attempt to bring CE to the Pi as described in this Chuckie Egg topic in the Raspberry Pi forums. He began with Raspbian Wheezy by trying to build two Linux ports of CE, described elsewhere on this page - ports from Mark Lomas and Paul Brook.

The resulting Mark Lomas' Native SDL Chuckie Egg binary for Raspbian Wheezy is probably as close to a clone of the original BBC Micro version as you'll find on Raspbian, without running an emulator. If that wasn't enough, it is joined by a build of the partial remake, Paul Brook's BBC Micro Chuckie Egg authentic clone binaries for Raspbian Wheezy.

The latter, at least, requires a firmware update to fix 8bpp palettised modes. Minimum version:
$ /opt/vc/bin/vcgencmd version
Jul  1 2012 12:48:16
Copyright (c) 2012 Broadcom
version 323014 (release)
To play simply, untar the archive, cd into the created dir and run either ./chuckie or ./aachuckie. Original keys are: a - Up   z - Down   , - Left   . - Right   Space - Jump.

Eventually, ukscone hopes in the future to get CE packaged and submitted to the Raspbian Repository.

Chuckie Egg for Flash Screenshot Neil Crutchlow's
Chuckie Egg -- 2006

This port of the BBC 32K release captures the spirit of the original very well and is played over the web - a browser with a Macromedia Flash plugin is required. Although it looks and feels great, it's not entirely accurate - the collision detection and physics engine are markedly different allowing Harry to jump up through platforms in a way that isn't possible in the original. The hens' movements, like virtually all CE ports, are also different to the original, though this is probably to be expected. There's no option to redefine the keys, so use the cursor keys to control Hen House Harry, and press Space to jump. There's also no high score table and the Hold and Abort keys have not been implemented - so your CE experience will be in one sitting! Small niggles aside, this is a very good choice for a quick CE blast especially for gamers who aren't on their own PC - as it doesn't require any local installation. Update: A recent update has seen the addition of a new section where you can now register to compare your score/level achievements with other users on a high score table, see how far you got prevously and level skip to get back there.

Scratch 1.4 / Flash

ChuckieEgg for Scratch 1.4 -- 2010

64-year-old Portguese Scratch coder Frederico has provided the first recreation of CE in Scratch, a basic web-based development environment aimed at young coders. A loose port, this game is understandably simplistic, and includes a very interesting change to the expected CE gameplay. There are no eggs or bird seed in sight, when you start the game! Instead, you guide your man around the platforms with the cursor keys and can press the c or m keys which will allow him to drop seed, at the cost of depleting your corn meter. The aim is to encourage the hens to eat the corn, and convert it into an egg which you can then collect. You need to pick up all 20 possible eggs without being hurt by the hens to complete the game. Overall, this is a nice, complete game which, although a far cry from the original, is notable for trying to adapt the game to work better in this target environment - traditional CE physics would just not be possible using Scratch. Interesting note: ffred's blue crest avatar is one of the symbols from the Portuguese flag, and is always placed somewhere on the first page of each of his projects in an inaccessible location. Like all projects published publicly on the Scratch website, the game is playable directly online through a browser Flash plugin and the Scratch (v1.4) source code is available for download under a CC BY-SA 3.0 licence.

Chuckie Egg for Scratch 1.4 -- 2011

An admiral effort from what appears to be a 13-year-old Scratch coder to recreate one of his parents' favourite games in this simple web-based development environment aimed at fledgling developers. This attempt is as basic as to be expected, though sticks closer to the original gameplay than the CE Scratch project from the previous year. Using the cursor keys, you must guide your man around the level and try and collect all 22 golden eggs. Unlike that last CE Scratch project, this version also allows you to jump using the Space bar. Although the graphics are as rudimentary as they come, special mention must be made of the graphic when you die - which has you laid out, looking like you've been crushed by a giant hot-dog! Like all projects published publicly on the Scratch website, the game is playable directly online through a browser Flash plugin and the Scratch (v1.4) source code is available for download under a CC BY-SA 3.0 licence.

Chocolate Factory, now Chuckie Egg 2 (a.k.a Choccy Egg) (defunct forum topic) -- 2008

A rare remake of Chuckie Egg 2. The bubbles have been omitted, just to get the game out the door, and the scoring system has been modified because the original system 'bugged' the author - there are no lives anymore, you just lose 100 points every time Harry is killed. If the score drops below zero, the game is over - the object is to complete just one egg and get it to dispatch with the highest score possible - where you'll receive a medal position 'rating'. The graphics are a mix of the originals, with some updated ones here and there. The game plays pretty well, though it feels like it could have benefited from a bit of spit and polish, before the final release. Definitely worth a play! Visit homepage to play online Java applet.

J2ME Chuckie Egg -- 2004

With the downloads currently disabled due to Elite Systems' recent J2ME licensed release, this site describes the development of an unofficial mobile version based on the BBC 32K version of Chuckie Egg. Having been given an exclusive preview, we can confirm that this game plays very closely to the original. The only flaws are the obvious ones relating to the variations in J2ME handsets - on devices with a smaller screen size than the Motorola V500 it was developed for, the screen can be cropped and modern handsets with more powerful processors run the game faster than required. On a Motorola V500 or equivalent device, though, this could have provided those Chuckie Egg fans who preferred the BBC 32K release a worthy alternative to the officially licensed port.
J2ME MIDP2.0 Chuckie Egg Screenshot Students from the University of Évora's
J2ME MIDP2.0 Chuckie Egg -- 2004
(original site is unavailable - it is archived by The Internet Archive Wayback Machine and the original software archives, hosted elsewhere, may also still be available: source tar-ball, graphics tar-ball, Nuno Morgadinho's university wiki (Portuguese) and Project details for Chuckie Egg J2ME)

A GPL'd J2ME implementation, this version uses MIDP 2.0. Originally written using the J2ME Wireless Toolkit and the Nokia Series 60 SDK simulator, without a compatible phone, it is fairly playable in software. The project was developed by a group of students as a school assignment but none of them have the time to continue working on the project so it has been orphaned. Patch contributions and further maintenance offers welcomed by (Tiago Fernandes, Cláudio Fernandes, Tiago Bilou and Nuno Morgadinho). If the original contact addresses do not work, Nuno Morgadinho has new contact details listed on his homepage. Most recently, 22 Nov. 2006, Tiago posted some further information on how to compile the code under Mac OS X.

There are no binaries available but the code itself compiles and we've tested it on a Nokia N70, where it fit the screen without modification. The first few times the game was started, it appeared to start the level well and looked good but, unfortunately, quickly locked up. However, after a few days with only occasional testing the game seemed to settle down and began to work reliably. On the whole, this application should work with any J2ME MIDP 2.0 compatible device but it might require some Java knowledge to create a working version for a particular setup - mainly to tweak the codebase to ensure the game works reliably with the specific hardware characteristics of that device.

A good proportion of the game itself is complete. Jumping on to higher platforms outlines some collision detection problems, making it very hard to retrieve the seed at the top of the platform stairway on level 1. Instead of leaping up the stepped platforms, Harry seems to jump through them and falls to the long platform below. On level 2 the number of hens is down to one and they're completely gone by level 3 which also exposes the lack of lifts which are customarily used to move around this and later levels. The levels themselves are fairly accurate to the original layouts but only the first four are implemented. After the completion of level 4, the game continues to loop round to this same level which, as there are no hens at all, means that the only danger to be concerned about are the gaps in the bottom platform - particularly across the shaft which normally holds the lift. The final glaring omission is the Mother Duck which is nowhere to be seen. That all said, with the GPL'd source code available, all of these issues could be resolved by a sufficiently talented Java programmer and it is also fairly simple to recompile the application with new graphics based on the original ports or any other theme. Note, however, that the language of the text within the game itself and the commented source code is Portuguese, not English - unlike the project's website. This is also the only version of CE available for many phones - for example, neither Bryan Mcphail's currently unavailable version or Elite System's official port worked as satisfactorily on the same Nokia N70's screen.

Tezxas running Chuckie Egg -- 1999

Tezxas is a Sinclair ZX Spectrum emulator for this pair of graphic calculators which claims compatibility with almost all games originally written for the ZX Spectrum. Though not a perfect emulator, it is supposed to run most games at a playable speed - slightly faster when using the greater capabilities of the TI-92 Plus - and has a surprisingly nice display, though the number of visible pixels is reduced, due to the calculators' screen limitations. A number of games are available for download and have been modified to ensure their best performance under Tezxas, including the SPECTRUM 48K release of Chuckie Egg.

Chuckie Egg DX -- 2001

The V0.33 beta release of this remake is supplied with The Chuckie Egg Professional's Resource Kit and can be played using the GameBoy Color driver within MESS (no BIOSes required). As a designated beta release, this remake does have a few rough edges - no in-game music, no pause function or high score table and occasionally, as in level 4, a hen will get stuck in one of the gaps. Based loosely on the BBC 32K release, this is overall a great release - although the sound effects are minimal, the graphics are superb - taking full advantage of the platform. Rather than attempting to squash the whole level on to the GBC's minimal screen display, this port scrolls around the level as Harry moves, which works surprisingly well - the only loss is the status bar at the top, which only becomes visible when Harry reaches the top of the level, or completes the screen. Most importantly, however, it captures the original gameplay brilliantly.

Probably based on the original SPECTRUM 48K release, this is a very loose and unfinished remake started because the author was offered help with the graphics. All Dragon BASIC 1.4 GBA compiler source code files and a precompiled ROM image are available for download. The level layout and ability to walk around is mostly complete but, as published to on 12th June, there are no hens or duck to be concerned about and the physics engine is fairly rudimentary. Striking colours, but as yet still missing enough features to be able to call it a complete game.

Chuckie Egg GP2X remake -- 2006

This remake is based on the original BBC 32K release and a .GPE executable is available for download. We haven't got a GP2X here at Bagshot Row but GP2X retro fans say that apart from a slight interruption in the sound and the lack of a high score table, this looks pretty faithful to the original. Rated 6 out of 10 at the time of writing, there are also more feedback comments at the gp2x File Archive.

Chuckie Egg SDL Port for PSP Screenshot Richard Rose, rosera aka agilemonkey's
Chuckie Egg SDL Port for PSP -- Feb 2010 (QuickJump Gaming Network forum discussion topic and The Dashhacks Network - PSP Hacks forum discussion topic)
(original site unavailable - download archived by QuickJump Gaming Network)

Requires custom firmware 5.xx. A one-player PSP conversion of Mark Lomas' hugely faithful source port of the BBC 32K Chuckie Egg release (although the illustrative screenshot used by's blog post describing this new port was actually from the ELECTRON release) for Sony's hand-held console, apparently created one weekend while Richard was watching rugby! This is a straight port of Mark's original code and is therefore exceptionally accurate to the original game. As far as we can tell, the only change is that the screen has been stretched to fit the resolution of the device and the controls have been updated to map to the PSP's buttons. We had quite a bit of intermittent slowdown when we played it, but that could have just been a quirk of the emulator setup.

Chuckie Egg -- Sept (0.5a Alpha) / Oct (1.0) 2014 ( forum discussion topic)

A brand-new mobile update of CE and potentially his last homebrew game for the PSP (also PlayStation Vita-compatible), Richie has stated that he tried not to modernise it in any way, by keeping to the original game design apart from the improved graphics. Whilst the physics engine is unsuprisingly different, this is a fresh new interpretation which looks delightful. We're especially big fans of the new sleek Mallard (now Father!) Duck, even if he is a bit flat and less rounded than we're used to! All the other sprites are similarly enhanced and whilst we're not enamoured with the brown-coloured platforms, it's pleasant to see different coloured hens from level 25 and the cage actually lifted when the mother duck is released - a neat touch. There's lots of minor differences to the original game here: the general look of the status bar and the fact that it now shows eggs collected, the slight changes in the level design - platforms not quite where you expect them (e.g. top left, level 4) & ladders unexpectedly broken (e.g. top right on level 2), odd physics where you can jump places you shouldn't be able to (e.g. across the first gap on level 3) & walk off lifts (also level 3) without immediately dying. There's even a difficulty option before you start the game, though this turns out to be a level select in another guise. It seems churlish to complain about much though - this is a fairly solid port which should appeal to the everyman CE player, even if it won't satisfy those who won't settle for less than a "perfect" CE physics engine. The new title screen graphic is very appealing, though we're not quite sure why it's the hen that appears to be running away! The only things that really aren't quite up to scratch is the minor carelessness of the mis-spelling of "Difficult" on the difficulty select screen along with the missing first and last characters from the copyright message on the title screen and, most glaringly of all, the sound effects which all sound even more basic and rudimentary than the original 8-bit versions. Even though the standard death tune from the BBC 32K version is in here, it's only used once at the end of a game - not every time you die, which seems a shame. If nothing else, the overall sound could be improved simply by borrowing the effects from Richard Rose's port above! Overall, a more than respectable port for PSP owners.

Chucky Egg 3D for Net Yaroze -- Apr 2002

An ambitious university coursework project, this is a Super Mario 64-style re-imagining of the BBC 32K release of Chuckie Egg in three dimensions coded for the Net Yaroze, a development kit for the PlayStation video game console. Provided by Sony to select UK universities, the Net Yaroze (DTL-H300x) package contained a special black-colored debugging PlayStation unit with documentation, software, and no regional lockout. The user provided a personal computer (IBM-PC or Macintosh in the UK) to write the computer code, compile it, and send the program to the PlayStation. Like most CE 3D projects, John's version is unfinished, though apparently it is complete enough that it should run on a PlayStation emulator. The included level is by the author's admission badly designed at the last moment, and the intended split-screen co-operative multiplayer was not finished. Everything else was progressing mostly according to the included design document, but the project eventually ran out of time. Published here along with source code.

Enterprise 128

Enterprise 128 Chuckie Egg Screenshot Enterprise 128 Chuckie Egg -- 19??

The Enterprise 128 computer was home to many unofficial Spectrum ports due to the hardware similarities between the two machines. There's no clues as to when or who converted Chuckie Egg, but the result is very similar to the original Spectrum release - the Enterprise is based around the same Z80 processor so, as would be expected, this is one of the few close conversions of the Spectrum release. In many ways it is identical, but there remain a few differences - the second set of keys are slightly different as the Enterprise 128 version supports a native joystick. Harry starts with six lives, instead of four and, most strikingly, the status bars of information at the top are all in blue, rather than mostly red with just the non-active players' scores in blue as in Nigel's Spectrum release. There is no little tune at the start of the game, or when Harry dies and the animated rectangles between levels are mainly red and blue, instead of many colours. This is almost certainly because the Enterprise's video mode has different attribution of colours to the Spectrum, and the missing music is based on a BEEP subroutine in the Spectrum ROM - which hasn't been simulated in this Enterprise port. There is also a pause just before the start of each life, which requires a key press to begin or continue the game, allowing you to take a little breather. The graphics are pretty much identical to the Spectrum release, even going so far as to suffer from the infamous Spectrum colour clashes when Harry or the birds climb or walk through ladders, eggs or seed. The sprites are also open to the same argument as the Spectrum - that they do not move as quickly or as fluidly as the BBC 32K version.

Harry's Hen House -- April 2009 (WIP)

Announced in Easter 2009, Harry's Hen House is a tribute to Chuckie Egg for the Atari 7800. Work is still in progress, but it's looking very good already. The background graphics have been converted to 160A mode (3 colours) though more levels are needed. Both the controls and Harry's jumping still need a bit of work and the latest posted version also needs a DLI to change the score/lives colours too. Looks well worth keeping an eye on, though.

Chuckie Egg -- 28 Dec 2010 (forum discussion topic)

From the coder of Chuckie Apple comes a port to the Usebox, a homebrew retro-minimalist open source video game console, less than three years old and built around only two chips. Available as a fully assembled unit or as a do-it-yourself kit, it is based on an AVR 8-bit general purpose microcontroller and features 4k RAM, 64k Program Memory ROM, 256 simultaneous colours arranged in a 3:3:2 R:G:B colour space and 4 channel 8-bit mono sound. Uniquely, the system uses an interrupt driven kernel and has no frame buffer. Functions like video sync generation, tile rendering, and music mixing are done real-time in the background so games like Chuckie Egg can easily be developed in C. The core of this version is a port of Mike Elson's Chuckie Egg for Windows, combined with the shell from Donkey Kong Uzebox. The RAM limit has resulted in the removal of the multi-player option, as well as the high score table and the sprite limit has necessitated less hens on screen.

Chuckie Egg 2013 -- 2013
Rob has returned to our favourite platformer for the 2013 #onegameamonth challenge and in March chose to update his own 2006 remake. Originally based on the SPECTRUM 48K release, this updated Windows release version comes with faithful updated sprites and all-new colourful backgrounds. It is also joined by brand new ports to both Android and HTML5. Our experience from downloading the Android version from the Play Store at launch is that the default controls were not immediately intuitive. After a bit of experimenting and making sure the device wasn't laid down on a flat surface(!), it didn't take long to pick up. Spectrum CE fans especially should get excited about this entirely free Android app which we suspect is going to rate higher than the official Android release did, even though there's no option to use the original graphics.

This appears to be a nice faithful port of the BBC 32K release by a Greek indie mobile developer, which is only a bit odd as he states that this was intended as a tribute to his favourite computer, the ZX Spectrum 48K. We haven't got a HP TouchPad, a Palm Pre 2 or Blackberry PlayBook but it looks great judging from the screenshots and YouTube video. Some of the comments on the Blackberry World entry seem to indicate that the controls are tricky on that particular version.

Actually a Manic Miner clone, this is worth mentioning because it contains a screen called The Hen-House for Miner Willy to navigate, based on level 1 of Chuckie Egg. Worth checking out, if only to see how Willy stacks up against our own Hen House Harry on this tribute screen! (Note: .z80 snapshot may not work with MESS)
