Are there different iNES mapper numbers that are assigned to the alternate MMC3 behaviors? I have some code that works fine in Nestopia (irq can be triggered 1 scanline later) which would be the later mmc3 behavior.
However, on powerpak and nintendulator irqs one scanline later are getting missed, which would be the earlier mmc3 behavior.
Is there a way I just choose a different iNES mapper to get the later mmc3 behavior, or should I just put in a spacial case in my code to handle the missing IRQ?
