Nintendo's version of Tetris for the NES/Famicom. Unlike the Tengen version, this game only supports one player (by default).

TetrisGYM is a training ROM that provides a variety of trainers and modes to practice on.

While originally based on the NTSC version of the game, the patched ROM supports PAL and NTSC gameplay types.

TetrisGYM makes extensive modifications to the ROM and is based on a disassembly that descends from TAUS: https://github.com/ejona86/taus
