After checking the traces I came to this result:
Code: Select all
74'161 __ __ VCC |01\/16| VCC WRAM /CE |02 15| NC PRG D4 |03 14| PRG A15 PRG D5 |04 13| PRG A16 PRG D6 |05 12| PRG A17 PRG D7 |06 11| PRG A18 GND |07 10| GND GND |08 09| WRAM /WE ------
I wired things up like I thought it would be with the bootleg but the game's not booting.
Connecting it like normal MMC3 I can dump the game fine and everything is equal when comparing both files (except iNES header, of course).
I tried wiring PRG A15-A18 ONLY to the '161 as well as MMC3 as well. Neither worked.
What am I missing or even doing wrong? Thanks in advance!
