I change it in various game, but can't notice anything different, except in the test ROM that fails.
What games use the alternate MMC3 IRQ?
Other then Crystalis??
What games use the alternate MMC3 IRQ?
Code:
MMC3_alt.nes
; Tests alternate MMC3 behavior. Some MMC3 chips also have this behavior,
; though their markings appear identical to those that have normal
; MMC3 behavior. My copy of Crystalis in particular behaves this way,
; but not my copy of Super Mario Bros. 3, even though both have a chip
; marked MMC3B.
