As subject anyone know if it's possible to reflash a bootleg cartridge to be a different game? Guilty Gear / Knights Valour bootlegs can still be picked up pretty cheaply from aliexpress but not Dolphin Blue, Mega Slug 6 etc. I'm wondering if it's just a case of reflashing some tsop flash memory...
