Just a quick note - you can get a Japanese Prototype of Star Fox 2. Not sure if there are any others, but I know that it is here.
"NintenDON'T sue me please haha"
If you want the Japanese rom you can go search for it somewhere else. All the roms here(or at least I think they are) are in English. If you can't find the rom then ask the request board for it.
