I recently modded one of my SFC with the super CIC mod and in game reset. Everything seemed to work fine including Starfox2 and mario kart so I was a little surprised when I tried SMRPG and nothing. ????
I tested RPG in an stock SNES and SFC with no issues so the game is fine, though I cleaned it anyway. Starting simple I tried just the SCIC I had been using before and it worked fine, tried another IGR/SCIC board and again worked fine?So with the wiring confirmed I decided to swap the SCIC chip from one that worked and RPG started like normal so the board is fine too. I put the non-working chip in the previously working SCIC board and nothing, ok it's the pic.
I figured it was the programming so I flashed it again, and nothing, tried many times the chip programming and verifying fine each time, still no luck. I confirmed the hex file I was using by re-flashing a working chip, so that wasn't the issue either. Finally I tried flashing the IGR code to the non-working SCIC chip and it seems to function properly there, so I'm using it as the IGR for now.
I can't really say for sure what the issue is but it is confirmed to be this specific IC as all others I have tried seem to work fine. I figure it's the less crucial operation of the IGR is why it will function there. Luckily I installed headers and sockets so testing was simple and it only took about 5 minutes to figure it out.
Just thought it was a strange issue and wanted to share with others that may be having issues that the actual PIC may be the problem, and more importantly make stuff you can take apart, headers and sockets are cheap and make troubleshooting so much easier.
