it's actually a really impressive port, plays well considering the lack of… everything on the Gameboy color https://www.gamesthatwerent.com/2025/12/resident-evil/
I played a good bit but I think the game is unbeatable. After the Yawn 2 boss fight there should be a cutscene (that is in the older build, but the boss fight isn't) that gives you a passcode, but that never happens. You just fight the snake, nothing happens, that's it
the game looks to be beatable! someone in the comments helped me out, there's an invisible hole in the floor you can find if you'll look around long enough and it triggers the cutscene that gives you the code!
I hope someone makes a mod that fixes the cutscenes and stuff, the first part of this one is just missing but probably still in the rom
also Bawkbasoup is streaming it now if you're interested https://www.twitch.tv/bawkbasoup
