So I recently got a hold of a reproduction of pokemon green. Turned out to just be a modified blue rom.... But after fiddling with the rom I dumped off the cartridge I found out my save was still intact even tho I didn't save using the emulator. If I try and save with an emulator it locks up, but it seems that my save file is saving in the rom itself and not to a sav file that would go in the ram because the cartridge I have doesn't have a save battery on it. Does anyone know how this is done? I would like to rewrite a actual Green rom to this cart but since is had not save battery it won't save unless its's modified to save to the rom.
