supern64 emulator controls quit working

[ledhead0014]

I have a galaxy s3 and use a n64 emulator called supern64. While playing banjo kazooie, which I have been playing for a couple months, my controls just locked up all of a sudden. I can't move or anything. This goes on for about thirty seconds and then I can move again for about a minute then it happens again.

I would just download an new emu but I don't want to lose my progress on the game.

Any ideas on how I can fix this?

Also this is only happening with supern64 not with anything else on my phone.
