HI here's my problem :

I play SMB on Steam, I went to Properties / Betas and selected the ogversion to speedrun it.

But when launching the game, it freezes at the 1st screen (the controller "plug this in for safety")

I tried to run it windowed / restarting my computer but it still doesn't work...

Does someone have an idea on how to fix this / have another beta of the game that allows us to pause buffer, to see if I can make it run ?
