When I converted Mario 3 to mmc5, I also converted the original mmc3 irq's to mmc5. On real hardware, there is a very noticeable jump of the irq scanline, everytime a DPCM note is played. The irq will fluctuate/jump about 2 scanlines. I'm not sure if I'm missing something regarding $4010 and my mmc5 irqs. Thanks for reading.
