I used a Retrode to dump the game to PC. The game will not load in an emulator or on a flash cart, I only get a black screen. I've also tried writing the game to an EPROM on a custom PCB, but that also only results in a black screen.
The cart PCB uses resistor networks, and depending what footprints you populate you can set the cart as LoROM or HiROM. The footprints that are populated on this PCB are for LoROM. When I load the ROM in an emulator, it gives me the following information.

I read that the SNES internal header was used as part of the approval process, but not actually used by the system to run the game. So that's why I thought writing the game to an EPROM would work, but I still only get a blank screen. I was under the impression that emulators and flash carts rely on this header in order to know how to run the game, so I was assuming it wasn't running because of a bad header, but from the above info it looks like the emulators are reading the header correctly. So I don't know why it's not working.bsnes wrote:game
