* It changes the waitvsync code to wait for the beginning of the vertical blank. The previous code simply checked if it was in the vblank and only waited if it wasn't. This caused 2 problems. The first is that when using syncrefresh, if there was enough time, more than one frame can be rendered during a single vblank. This is why syncrefresh would have odd behavior such as the game speeding up or slowing during during less cpu intensive sequences. The second problem is that the retrace line could sometimes be seen because while the code checked to see if it was in the vblank, it did not check where in the vblank it was so it might be at the end of the vblank and by time the frame is rendered the monitor could be out of the vblank.
* It removes the waitvsync only if game speed is above 95% restriction. This restriction would only cause waitvsync to vacillate between on and off depending on game speed. If someone enables waitvsync and it is too slow, then it is.
* When syncrefresh and triplebuffer are used, MAME would run the waitvsync code anyway. The triplebuffer code takes care of this and having MAME wait for the retrace in the waitvsync code anyway is a waste of time and causes timing issues on some hardware. If triplebuffering is enabled, then there is no need to run the waitvsync code because triplebuffer already does.
