Send Nintendo an email and ask them if they R fine with all their games for download here. They R not.
Forums and sites claiming U can legally have a ROM if U got the original R lying, U can not.
Forums and sites claiming U can DL a game U don't own, but gotta delete it with in 24 hours, they R lying too, U can't.
They just made that up back in 97 or something, when ROMsites got off the ground, just to try and make it look more legal.
There's no such things as a legal ROM, unless the copyright owners says they have become freeware. Until then, the game is copyright protected for 75 years and thus illegal. Seeing as how all Nintendo games R ESA protected, none of them is legal, and they never will be, until Nintendo says they R.
