There's already bunch of repos on the site. The tricky thing is what version it is or who made it. There's a lot of people making reproductions of translated Japanese games and rare game. Some of the producers make a good effort of placing their own branding on the carts to make it obvious that it's a reproduction, while others make 'em to look almost like the originals.
While translated repos I don't mind, the act of making a "reproduction game" and selling them is bootlegging and is illegal in most countries.
