Hello i'm looking for the pinout for punchout or mtpo. i read somewhere it has a "funky" pinout.
I have a copy of mtpo that refuses to boot. I've only ever got a white screen, no gfx or sound ever. It's the only game I have I can't get to work.
I have seen the white screen before. Dirty cart contacts can be the problem or 72 pin connections. So i tried the usual fixes cleaned the game cart connector (numerous times) and i tried changing game alignment in the tray. I then tried taking the top off the nes and running the bare pcb.
I'm starting to think there may be something wrong with the cart? i had a dev cart with a broken trace(an PRG address line - fixed by running a wire) it would only boot to a white screen.
I looked the board over and would say it looks in pretty good condition. I don't see anything wrong with it. I got the cart, mmc2 and 128kb chip pinouts and am in the process of checking the board. I'm testing the traces from the chip to the egde pins.
Was hoping someone had some advice or ideas or had the pnrom pinouts. Maybe one of you guys have run into this problem before. Any help would be appreciated.
oh and what's the difference between pnrom and peeorom?
