as far as I can tell this hacked version actually runs quite a bit faster than 192mhz.
Because I have tried running V 2.0 (unhacked) at 192mhz with sound set to 16500, and then running the hacked Beta 7, and consistently get faster FPS in the hacked beta. usually by about 5 fps.
Also, the sound is more accurate in the hacked beta, at 192mhz in unhacked v 2.0, the sound is a bit too high pitched and fast, in hacked beta it is perfect as far as I can tell.
