Gens/GS II Compatibility List
From Sega Retro
This is a preliminary compatibility list for Gens/GS II.
NOTE: Only commercially-released games should be added to this list. A separate list may be created later for hacks, homebrew games, and/or bootlegs.
For each game, the following information should be listed:
- Game name, region, and CRC32. (Region may be JUE for region-free ROMs.)
- Save type, e.g. SRAM, FeRAM, or a type of EEPROM. (Use N/A for none.)
- Does the game work on Gens 2.14, Gens/GS r7, and the latest Gens/GS II? For Gens/GS II, a `git describe` tag should be included.
- Any issues specific to an emulator should be listed in the emulator column.
- Any additional notes about the game.
