File CRC32: B7862D15


GE vertex format: 0x12000122 (hardcoded in ELF?)
u16 texcoords, s8 normals, s16 positions
13bytes lenght
Example:
B40B F527  4F 63 0E 00  9F3F 9DD6 72F9
u16 texcoords:
U 0x0BB4
V 0x27F5
s8 normals:
NX 0x4F
NY 0x63
NZ 0x0E
s16 positions:
X 0x3F9F
Y 0xD69D
Z 0xF972

GE DRAW CMD and GE vertex addresses are 16-byte aligned, padding with zeros when necessary.


Step-by-step rendering with PPSSPP GE debugger:

Game conditions.
- Time attack game mode.
- Default race camera.
- Static vehicle position (not moving).
- Game paused.
