- Used for mmmbanc, needs SH3 serial support.
Remaining Video issues
- measure h/v video timing
- mmpork startup screen flicker - the FOR USE IN JAPAN screen doesn't appear on the real PCB until after the graphics are fully loaded, it still displays 'please wait' until that point.
- 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?
