Great thank you ! I just got Usamune, it works fine. I watches this vidéo : where he says "by the way you can save at any moment by pressing start and load it by pressing all the c buttons at once" but this doesn't work for me do you think there is a way to change the buttons involved ?

Hello everyone. I would to train my speedrun on SM64 and i saw this guy : He seems to just push a button and restart before he missed his move. This is exactly what i need to pracice. Does anyone knows how to do that ? (or approximately the same) Maybe he explains that some times but my german is very poor... For information i play on an emulated game via project64. Thank you so much if you have the answer.
