    Work it out using ucon64. Should be easy enough. Find out cartridge type, size, etc and then find an appropriate donor.

    I've had major problems in the past getting this ROMs properly headered, although for use on a real cart it shouldn't be that difficult. From memory, I just fired it up in ZSNES and looked at the info in there.

    Looks like they are both LoROM games with no SRAM, so U1 mask rom and U2 cic, the 4MBIT one would probably need to be expanded with Lunar Expand to 8MBIT, burn the games, test them in a socketed LoROM cart one by one and if they work just solder them into a donor cart each

    Ah I remember now. The problems I was having was trying to get them to run on my Super UFO 8, which needs a proper header/checksum. If anyone manages to get them to run on the Super UFO I'd love to know how!

    Sorry, I should have been more specific: I could find a donor cart pretty easily. I just wanted to know if there were any special chips used for diagnostic purposes. Looks like there is not. Thanks!

    Missed it thanks.
    So SNES Burn-in Test Cartridge does need SRAM.
    I haven't made one myself but would be interesting to see if it would still run with no SRAM

    Pretty sure it doesn't need SRAM, at least the one I made didn't need it.
