2000 Capcom / Virgin Interactive / HotGen
Platform: Gameboy Color
How can you possibly squeeze a 32-bit PlayStation CD ROM game into a small Game Boy Color Cartridge? Well, HotGen would attempt to do just that with a conversion of Resident Evil in mid-1999 and to make it as close as possible with similar 3D perspectives using scaled sprites.
There were delays and a lot of struggles to cram everything in. There were of course a number of restrictions and tweaks made along the way, but HotGen had a pretty decent stab at it and had a title which was certainly pushing the 8-bit hardware.
Retained were the original game’s locations, viewpoints, puzzles, pre-rendered backgrounds and dialogue. Characters and enemies were software-scaled, with technical compromises required due to the GBC’s limited CPU power and storage. Speech was replaced with text windows, but the structure of the PlayStation original remained largely intact.
When we spoke to developer Nigel Speight as part of our book coverage in 2020, he had the following recollections about the development:
“If I remember correctly I would say the game was about 75-85% complete. Originally the game was supposed to be about 35% of the original PlayStation version and we were going to elongate the storyline to keep reusing the rooms. However, as time went along Virgin kept upping the cartridge size and wanting more of the original content in. If I remember correctly I’d created an editor that allowed the 3d to be aligned to the screens and objects placed etc and I think that the last build we made didn’t include the final amount of content me and the artist Martin Smith had created.”
The game had been shown at places like E3 in 1999, and had been planned for release by the Christmas of that year – though delays meant it slipped into early 2000. By February 2000, the game was nearing completion and was being tested. However, Capcom decided to cancel the title, feeling that the game wasn’t up to scratch.
Assistant programmer Pete Frith (back in 2020 when questioned by us) couldn’t recall the completion state, but felt it was more 98% finished, as there was a lot of communications between the team and QA testers at the end. He also recalls that the story they were told regarding the cancellation, was that the original creator of Resident Evil didn’t feel the GBC was worthy of his creation, and that he had personally instructed the cancellation. He also informed that the lead artist Martin Smith had sadly passed away.
Where Martin focused on the backgrounds, Simon Butler did the sprite work on the game. Mark Cooksey was then on hand to create all the music and sound effects, though many would not get properly integrated it seems.
Thankfully, in 2011 – two separate builds were preserved thanks to Kiff Storey and Bowker. One version was quite near to completion, but was missing intro titles and had debug screens on and was felt to be around 90% complete. A long-play online confirmed that the game wasn’t completable either for both characters.
In late 2025 however, Games That Weren’t have now preserved a final version of game at the point of cancellation and we have it here for you today to check out thanks to Pete Frith providing everything. Again, it isn’t 100% complete (perhaps now 98% – based on Pete’s estimates) – but there is more content and it *might* actually now be completable. Due to time constraints, we’ve not been able to sit and play through the title fully to confirm, as there might be scenes that glitch/bug out – if you find that it is, please do let us know!
Crucially, we know that the Tyrant seems to be present at the end (see below) and its possible to trigger the end sequence compared to the earlier builds. We have a hack further below that jumps you near the end, so that you can see this for yourself.
The debug data present in other builds has been removed in the final build, and there are a set of introduction credit screens present in this version. Also, hacking through the game – the end sequences are in place too, which gives promise that the game may be completable in its current final state. Just in case it isn’t, we’ve created a few hacks which allow the following to unlock some unseen content:
1) ResiEvilHack-EndingSelector: This allows you to just select either character and jump straight to the end sequences for both.
2) ResiEvilHack-TyrantSegments: This hack jumps near towards the end of the game, where the tyrant is now walking around the final outside scene if you select Chris Redfield. If you select Jill Valentine, it starts you in the lab with the tyrant moving around (though its just their silloette).
You can’t seem to kill the Tyrant with the knife with Chris (though you might be able to find a weapon nearby). However, if you play with Jill and navigate towards the outside helicopter pad – the tyrant is there, and you can use your gun to kill them – triggering the end sequence.
3) ResiEvilHack-SceneNMusicPlayer: This is quite a cool hack. Firstly, if you select either character – it will play through all the animated scenes for that player in sequence. It is likely there will be a few scenes here which were not used in the game or integrated. Then if you press “B” on the same selector screen, you will be able to play through all the SFX and pressing “SELECT” will cycle through all the tunes created by Mark Cooksey.
In a note found to the developers, Mark listed all the music and SFX as follows (with his original descriptions):

In addition to this, we have extracted out a set of assets used for the game – which may contain sprites/sequences not used in the final game. Also, the original WAV samples that Pete Frith created from his voice to make the speech on the title screen – including some versions that were not used :)
What else have we established so far?
- Zombie deaths are still not properly implemented it seems – they just collapse to their knees still. Wondering if that may have been a Nintendo request to tone it down?
- It seems all artwork was complete, even if the game was not 100%. Sprites could be 98% complete – especially as death sprites are missing.
- Hunter is present in sprites, but doesn’t seem to be used? We might be wrong. Zombie used in one scene where it bites Rebecca when it should be the Hunter. Zombie is often used as a placeholder.
- Wesker and Barry sprites are exactly the same.
- Some sprite colours are set wrong, Rebecca is blue in one section – colours not properly set for all characters in the scenes. It seems that there was a limit to character colours that could be set in one room . i.e. 3 characters. Problematic if the same scene has to be re-used with different characters with different colours. This may well have been something to fix at the end.
- Some cut scenes seem to be unfinished – they can be viewed in bits. Not all of them seem to be called yet in the game. Segments and animations missing, including the Tyrant coming out of the glass and moving towards Chris and Wesker dying. Music missing from Piano scene at this stage, not all SFX utilized.
If you spot anything else – please feel free to get in touch or leave something in the comments and we’ll update the page over time. For now, we hope you enjoy taking a look at what has been recovered and enjoy the findings so far. We have also included two bonus builds that we also located which will have some minor differences too.
With a huge thank you to Pete Frith for allowing us to preserve and for the assets and to Nigel Speight for his recollections.

Good to see my sprites again after all these years.
It wasn’t the most fun I’ve had on a project by a long shot, but it was interesting to say the least.
