Ok, thanks Ade I'll set it again and hopefully the bug will be gone, one thing I noticed is that in the opening of kof96 the fps is about 55/60 without overclock, I think it has increased, will change the path and test again.

I've changed the path but still get the bug especially if I minimize and return, volumen changing sometimes doesn't crash... But as I said this version seems to be faster with less slowdowns and more fps. Thanks Ade. Forgot to answer about the hotkeys, the hotkeys are written on the gngeorc txt file, so is the same as all the other keys, I think. I have to check because I remember I set them up on your gui directly, but maybe they get printten on gngeorc as we change the configurations on the gui and I have set them since you introduced the feature.
