1. Teenage Mutant Ninja Turtles 3: game will freeze in second level
    In level 2, this game sets the scanline counter to 0 and expects the interrupt to be triggered on every scanline. This is not a conventional MMC3 mapper behaviour because normally if game does so, the interrupt will be triggered only on the next scanline. Here is a patched version of game that fixes that behaviour

  2. Karnov: Game has wrong graphics during scroll
    This game was physically released as mapper #206, which is MMC3's precedessor, that has no mirroring control register. Publicly available ROM has assigned MMC3, which is wrong. Special routine was added to set MMC3's mirroring register to correct value

  3. Tetris 2: Totally wrong graphics
    Game declares only 2 CHR banks but tries to use banks 2,3. CHR-data was mirrored once so all CHR banks 0,1,2,3 can be now accessed safelly.
