Some more uninteresting (as in they all work perfectly) games tested:
Mangchi The Hammer Boy doesn't like dgVooodoo 2.55.1+, otherwise no problems. Minor graphic glitches with resolution forcing.

Room Zoom: Race for Impact doesn't like dgVoodoo 2.55.1+ either, but no other problems.

Kaan: Barbarian's Blade also seems to have a problem with dgVoodoo 2.55.1+, but otherwise has no problems.

Gift seems to share enough similarities with Kaan that I think it runs on the same engine, however it works fine in dgVoodoo2 2.55.1+ and shows black screen instead of FMVs when resolution forcing is on.
