>>36397183>save data directly from the cartridge and using it on a emulatoryes, because a PC emulator is designed to read GB ROM and save data and translate them to workable file formats for PC, so it can easily be translated back. The 3DS emulation does not work the same way, most likely, since it's using proprietary non-PC hardware and isn't designed to read real GB cartridges
>>36397194this is probably right, although what exactly you'd need to edit probably differs from a PC emulator save and the 3DS emulator save. I don't know that any documentation on that exists. And again, getting the hardware to inject files from a PC to an actual GB cart is a big hurdle.
