There is also other games that aren't rendering lighting correctly even Xbox intro. Halo 2 included also. https://github.com/mborgerson/xemu/issues/580

Looks like some more things might have lighting issues. https://github.com/mborgerson/xemu/issues/678

Connecting dots since there's a comment on #840 indicating that it partially solves the intro issue.

840, #720, and #832 all have varying effects on lighting/shadow behavior (depending on the mechanism used by the game) and generally this bug should be re-tested once those PRs are merged.
