I'm working on a little hobbyproject, porting mapper 3 to MMC1. But I'm missing something concerning CHR-swapping (or some bugs I've caused?). I've patched the mapper 3 CHR-swapping to MMC1, but to get the correct bank, I need to swap to a banknumber way off where it should be.
When it swaps, the target is located in bank 10, but I need to swap to bank 20 (I've only got 16 banks) and then it's correct. I don't get it (Tested in Mesen).
Anyone got any hints on what I should check? The MMC1 control register should be ok.
