Worth to note that CReplay::NextFrame seems to be not related to replay per se, but to car physics. | This in turn skip CTimer::GetTimeSeconds((void)) in function CReplay::NextFrame((CDrivingControls *)).

| No mipmapping support || Emulator does ignore the mipmap layers, probably for performance reasons. It is processing only the level 0 texture base pointer specified in the TEX0 register. There are games writing garbage data into that memory area, when the mipmap level is different than zero. As a result, a garbled texture is shown instead of a correct one. || Ace Combat series, Ape Escape 2, EA Sports F1 series, Harry Potter series, ICO (psuedo volumetric rays), Jak and Daxter series, Nickelodeon Barnyard and Nicktoons Unite (very strange implementation), Ratchet and Clank series and more. | | No mipmapping support || Emulator does ignore the mipmap layers, probably for performance reasons.

It is used as a fake transparency effect in some games by merging the two display circuits. || Metal Gear Solid series (heavy used in the MGS2 on the water and reflection effects), Gran Turismo series (ghost cars), Raw Danger!
