Hello guys,
I'm trying my first NES reproduction tonight and I would like some advices on how to do the rewiring.
I am using EPROMS AM27C040 with the following shematics:
I am trying to do a Bubble Bobble Part 2 from a Teenage Mutant Ninja Turtles 2. I desoldered the CHR and PRG Roms from the TNMT2 PCB and I am getting ready to try and solder my newly programmed EPROM on it.
My question is how do I know which pins from the EPROMs need to be rewired? I found lots of different schematic similar to the one of my AM27C040 but I'm not sure which one I have to use. Is the same pinout used for all PRG and CHR rom for every different mappers? Where can I find that information?
Thank you for your time.
