On one hand, hacking/speed-running/homebrew and other gaming niches should make it so older games like Mario N64 remains popular longer... On the other, I doubt niches make much of a difference for Nintendo's bottom line, and considering their track record, I assume they would kill all sorts of hacks around their platforms, if they could.

So, fuzzing tests [1] seem to be in order for Nintendo games... :-)
