We cope with that with an hack in the Blitter but there must be a register to do the trick Revisions: 05-05-2002 David Haywood(Haze) - improved Wec Le Mans steering 05-01-2002 Hiromitsu Shioya(Shica) - fixed Hot Chase volume and sound interrupt xx-xx-2003 Acho A. Tang [Wec Le Mans 24] - generalized blitter to support Wec Le Mans - emulated custom alpha blending chip used for protection - fixed game color and sound volume - added shadows and sprite-to-sprite priority - added curbs effect - modified zoom equation to close tile gaps - fixed a few tile glitches - converted driver to use RGB direct - cloud transition(needs verification from board owners) - fixed sound banking - source clean-up TODO: - check dust color on title screen(I don't think it should be black) - check brake light(LED) support - check occational off-pitch music and samples(sound interrupt related?) * Sprite, road and sky drawings do not support 32-bit color depth. Certain sprites with incorrect z-value still pop in front of closer billboards and some appear a few pixels off the ground. They could be the game's intrinsic flaws.

It is possible the video hardware performs additional sorting. The color code in the original sprite encoding has special meanings on the other hand.
