Didn't tested much since it appears to work fine, had to disable it for movies through.
Interesting note: while most games use frameskip to get 30fps, those two actually sleept through every second frame;p.

Edit: added conditionals to avoid repeating the code, also since PD games were soo easy, I did same for full games I had, althrough bit different, since I did it through assembly, also had to disable the 60fps on extend loading screens to avoid hangs(edit2: and some more screens like save screen which still randomly could hang;p/edit3: same thing, hopefully all "random" hangs fixed now;], edit4... but still made an edit just to simplify it;p).
