Hi guy's, I'm new to the forum but have been visiting it for a little while.
Looks like you have very nice nes knowledge community here.
I decided to join because I'm getting interested in making my own nes carts and have some questions I couldn’t find answer. I did some search here but I get so many results I can't find the answer.
Now, the question. I have eprom writer en some new 27C256 eproms and I want to use them on a TKROM board. I found wiring info for mapper 4 and pinout for 27c256 eprom. But how do I rewire the 28 pin eprom to match the mapper 4 wiring since 27c256 doesn't have 30 and 31 pins?
Is it possible at all to use 27c256 on TKROM or do I need another type of eproms?
