/*
1. Notice: This rate can currently not be calculated with any accuracy at all when idle skipping
is on (the suggested tick rate in that case is much to high in proportion to the actual FPS)
2. When dual core is enabled the CommandProcessor allow some elasticity in the FPS/VPS rate. This
is especially noticable in Zelda TP who's FPS/VPS for me varies between 0.25 and 0.6 as a
result of this.
3. PAL 50Hz games: Are 'patched' so that they still run at the correct speed. So if the NTSC 60Hz
version has a FPS/VPS of 0.5 the 50Hz game will run at 0.6.
