I am not sure what I'm doing wrong. I'm just doing some simple CHR-ROM swapping and it works fine in FCEUX for example. But a tester confirmed it doesn't work running on PowerPak (=wrong gfx).
I am no expert in MMC3, whatsoever, but here's my code (see below). See anything obvious? Thanks in advance.
