ZSNES board

Yeah, I'm trying to run a movie. I tried the newest version of ZSNES and it resulted in a desync, as I expected.

Well, the good news is that DOS Box runs ZSNES 0.989c. Unfortuantely it runs it very slowly.

After the battle, the speed will return to normal. I have tried using ZSNES 1.36. Not only do I get the same speed effect,...
