So I've seen some players portaling under themselves (with the corefall strat) after incinerating all cores, which puts them out of bounds. I missed one core, so I portaled under myself to grab it and put it into incinerator. Does this invalidate my inbounds run?

Some short question: is PC emulator allowed? Will it be qualified if I play on emulator? If sm64 not, can rom hacks be done on emulator?
