This is probably one of the stupidest questions ever asked here, but I have a useless Metroid Hunters First Hunt cartridge(a demo for the actual game). Going to GodMode9, I can see there's [C:] GAMECART, which contains my game's .nds and .trim.nds files which are on the cart. Can I delete them and put any rom I want?(In my case, a long lost game, the actual Metroid Prime Hunters). I am asking because I think the cartridge connections are actually what makes games work, so this wouldn't work. By the way, I don't really know if this is the best section to post this. Thank you.
