Tetris GB Recomp is a native Windows port of Tetris for the Game Boy, made by mstan by statically recompiling the game's SM83 code into C, with the Game Boy video and sound emulated around it.

The author believes it is fully playable, including the A-Type and B-Type games. It is a small, early project with few extras.

The author says AI tools were used heavily in making it.

The download contains no game data. It needs Tetris (World) V1.0, dumped from your own cartridge.

## How to set it up

1. Download the Windows zip and extract it.
2. Run `Tetris.exe` and point it at your Tetris ROM.
