Some games do check if SRAM is present (e.g. Demon's Crest) eventhough they do not have it. Always use only the components that are needed for each game. I have made a few Mickey & Donald 3 carts and all of them were working fine. This might be the issue as I'm using components that the cart do...

I don't have an answer, but I can give some warnings: Likely: Sometimes translations/hacks don't work on the real system, when they were unable to test on a real system during development. Older SNES emulators are notoriously forgiving about things that completely choke a real SNES. Unlikely: Somet...

I don't a very helpful message but I wanted to ask, why do you say 'wasting EPROMS'? Are you not able to erase them? If you don't have an EPROM eraser, you can set them outside in direct sunlight for a week or two and they should erase. It's because, at least for me, it's very hard to desolder them...

Hi there, I know this is a very specific question, but it's driving me crazy; well I had some MURAMASA PCB boards with some games that I don't play, so I decided to replace its EEPROMs for something different. So everything went fine until I tried to make the translated version of Mickey to Donald M...

Or whatever, I guess most photographers would die for making a shot like that once in their lifetime : ) hahah i didn't se...
