It would be nice to have a way to dump the cartridge firmware/rom and/or write it to an external device (such as MODE for example); some rare cartridges have yet to be dumped.
The "Dump Memory" option already supports this use case. From my notes the cartridge is at: Cartridge backup memory (address: 0x02000000, size: 0x01FFFFFF).
