Screen names
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[1].
Debug functions
Some debugging functions remain intact, and are mapped to buttons which do not exist on the released cabinet itself[1]:
- 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.
