I'm using a TLROM board. I applied infidelity's MMC3 patch from v9.1 to Teenage Mutant Ninja Turtles (U).nes and the resulting rom plays fine on my Everdrive N8 and in FECUX.
I split and pad it my normal way using famirom and solder the programmed eprom down using these directions:
PRG ROM:
Pin 1 Nothing!
Pin 2 Hole 24
Pin 24 Pin 16 (or another ground)
Pin 30 Hole 1
Pin 31 Hole 2
CHR ROM:
Pin 1 Nothing!
Pin 2 Hole 24
Pin 22 Hole 31
Pin 24 Hole 2
Pin 30 Hole 1
Pin 31 Nothing!
The resulting game starts but is graphically garbled and then freezes. Tieing A18 and A19 to high/low has no impact.

Anyone have any ideas?
