Resident Evil for GameBoy Color was cancelled at 90% of development. The ROM was later released to the public. Due to it’s incomplete nature, the game had a lot of glitches requiring hacks to continue at certain areas.

This patch fixes the most important issues so the game can be played from start to finish without hacking. However, there aren’t any programmed endings, so you’ll be stuck at the final room and there’s nothing that can be done about it.

This patch is only to be applied to the 1st cart ROM, not the 2nd.

Changes made to the game:

• Originally you couldn’t access the Plant 42 room because you couldn’t use the red book. Now there’s no red book. You only have to take the white book from the bookcase and the main door to the Plant 42 will open (the big door, not the one behind the bookcase in the small room).
• The door to the heliporter was opened by default. Now it is closed like it should be. It will open when you exit the Tyrant room.
• Removed the collision of the left wall in one of the lab’s rooms to be able to access to the morgue and one of the MO Readers. It was impossible to access that room without hacking.
