I have two copies of Star Fox 64 in my hands, and the collection wizard states the code on the game is "NUS-NFPE-USA", but both of these say "NUS-NFXE-USA".

The "Not For Resale" version has this code, according to the collection wizard, but these two copies seem like normal copies to me. Error or am I missing something?

*Edit: I must be missing something, my OoT cartridges also don't seem to match up with the codes on the wizard.
