TODO:

- Super Hi Impact freaks out during play.

- When the Porsche spins in Narc, the wheels are missing for a single frame (may be an original bug).

- Terminator 2 freezes while playing the movies after destroying skynet. Currently we have a hack in which prevents the freeze, but we really should eventually figure it out for real.
