SegaSonic Cosmo Fighter/Hidden content
From Sonic Retro
- Back to: SegaSonic Cosmo Fighter.
Text strings can be found starting at 0x4F2 that would have displayed what screen the player is at in-game. They also indicate that the game's title may have been "Sonic Jet" during development:
SONIC JET : TEST MODE SONIC JET : WARNING SONIC JET : TITLE SONIC JET : DEMO SONIC JET : OPENING SONIC JET : GAME SONIC JET : ENDING
An orphaned initialisation routine starting at 0x390 can be called to display these strings during gameplay, but doing so can corrupt the graphics.
Some debugging functions remain intact, and are mapped to buttons which do not exist on the released cabinet itself:
- The flag at 0xFF800A allows the player to pause the game. This is mapped as P2 Button 1 in MAME.
- The flag at 0xFF8006 controls the game speed. In MAME, P1 Start decreases this value, while P2 Start increases it.
