Note:
I haven't yet figured out how to port the codes from the PAL version, all of these were found by me. If anyone wants to port the rest of the PAL codes, there's already a PAL unlimited stars code that should make this easy, but the methods described in the tutorial aren't working for me, or I am doing it wrong.
