Tested and working on netemu. Frame rate is fully fixed! Background is mostly there...just no HUD right now.
And sorry about triple posting. I literally cannot edit my posts after 15 mins.
EDIT: HUD/character select is missing in Alpha 1, so that one is still unplayable. HUD is actually present in the rest of the games (Street Fighter Alpha 2, 2 Gold, and 3). Just missing some background stuff in those, but they should all be fully playable now.
Y'all should do more testing though since I don't fully know the game that well.
