I've already tried DXGL and dgVoodoo without success (they stop the flickering but one produces a crash when you enter a dungeon and the other makes the dungeon wall textures disappear); windowing programs don't hook the game either (DXwin and d3dWindower)-- I'm starting to think it may have SOMETHING to do with video. Whenever I record footage of the game using BANDICAM or FRAPS the flickering in the recorded footage is machine-gun rapid-fire unlike when the game is running normally where the flickering is subtle and random but consistent (both ways render it unplayable anyway).
why would recording software make the game's flickering go into overdrive? I don't even have any video codecs installed whatsoever. And of course I already tried launching the game without ANY video recording software installed and it still did it's flicker stuff.
So weird. The whole thing is extra stressful because I'm supposed to finish translating the game and I don't feel like doing so because the game is frankly unplayable.
