I have posted a thread talking about this before but because speedrun.com was under maintenance, it got deleted (i'm assuming) this video is me comparing what should happen and what's happening to me and this video, is of me trying to do the spindash later but with no success of doing the skip (if i spindash sooner than i did in this video, i will end up failing like in the first video) i have tried a lot of ways of getting tails to open the door but with no success, i even have a save state of me doing it correctly, so i don't know why i can't do it again

I need to know what GBA emulators are valid for speedrunning
