K I know this shouldnt belong here but I dont know where else to ask this at. But I recently just got a n64 cuz i never had one when i was younger. I was a playstation kid. But I was wondering what exactly is it called for those game cartridges that are blank. They got like a certain amount of room so you can upload roms onto them. I know they got them for the gba. Can someone point me in the right direction cuz I've been searching for a while. Thanks in advance.
