@ -161,14 +161,13 @@ Remaining Video issues
- is the use of the 'scroll' registers 100% correct? (related to above?)
- Sometimes the 'sprites' in mushisam lag by a frame vs the 'backgrounds' is this a timing problem, does the real game do it?
Speedups
- Blitter is already tightly optimized
- Need SH3 recompiler?
Blitter Timing
- Correct slowdown emulation and flags (depends on blit mode, and speed of RAM) - could do with the recompiler or alt idle skips on the busy flag wait loops
- End of Blit IRQ? (one game has a valid irq routine that looks like it was used for profiling, but nothing depends on it)
Common game codes:
- During boot hold P1 Right+A+B+C and P2 Left+A+B+C - Forcibly initialise non-volatile data (EEPROM or NAND settings area)
- During boot hold P1 A and P2 A - Reset random numbers generator at each game start. Probably was used during testing or/and competition events.
