Speculation - Observations

> Redfaction and GTA 3's IOP is good.
> Redfaction defaults at newprog.
> Mipmapping is imperfect, the simpsons hate it.
> Clamping works best on Jak x
> Mipmapping works best on War of the Monsters
> A 0x200 delay restores the EE-VU0 sync.

Diagnosis

Grey screen > GIF
Freeze with repeating audio > looping IOP or EE
Freeze with no continuing audio > VU0 timing
Crash > VIF1 timing, VU1 cache policy, or segfault
SPS > VU timing/rounding/clamping
Incorrect physics = soft floats, clamping, or flags
Black screen > EE receiving incorrect data from VU/IOP/DMA channels
