Sandstone Engine build 797

Wheels: a car carries one wheel mesh, modelled for the right-hand side, and the left side is that mesh mirrored across the axle. Drawn unmirrored, the left dish faced into the arch and the wheel read as pressed in and dark. Both sides now roll forwards as well; the spin sign had been inverted from the start and stayed invisible while both sides were wrong together.

Audio: the PS2 stream layout is read correctly, feeder threads get partition-backed stacks, and SFX stop at their end flag instead of clicking. Interiors draw decals rather than alpha-testing them into black specks. The HUD waits until the player is actually seated before showing the speedometer and the radio.
