SegaSonic Cosmo Fighter
|SegaSonic Cosmo Fighter|
SegaSonic Cosmo Fighter was considered a holy grail among Sonic game collectors due to its obscurity and how few units remain in the wild. Luckily, a machine was found and the ROM was dumped in 2017. It's a ride machine for young kids where you fight Eggman.
There are some strings starting at 0x4F2, that would have displayed where the player is in the game. An old initialization routine at 0x390 can be called to display this text in-game, but it tends to corrupt graphics at times. Note that these appear to reference a working title, Sonic Jet.

Some debugging functions are in the game fully intact, but refer to controls that no longer exist on the machine. The flag at 0xFF800A allows the player to pause the game, mapped as P2 Button 1 in MAME. There's also a flag at 0xFF8006 which controls the game speed. P1 Start decreases this value while P2 Start increases it.
