    Lightbulb Voodoo incompatibility

    It's well known (and documented on the official PSO PC support site even) that the 3dfx Voodoo series of video cards (starting from banshee, up to 5) crashes the game when you transport to Ragol. There's some ancient threads about it here. It's a shame since it looks good and shows promise with rendering correctly until that point.

    PCem recently gained Voodoo Banshee and Voodoo3 emulation (no wrappers - all LLE on the CPU), and can run the game up to the point of Pioneer 2 and reproduces the known crash issue. It happens no matter what driver you use (Official or 3rd party, Win98SE/Me/2000/XP, etc). I don't know the exact cause either. I'd assume texture memory (log says it fails at Direct3DTextureCreate), but 16mb should be enough for the low setting (and non-3dfx 16mb cards are supported by PSO, but are not currently emulated).

    I wonder if that emulation's enough to relentlessly debug towards the creation of a possible fix patch? Just curiosity speaking / thinking aloud... 3dfx's been deader than the Dreamcast and still sees use in many retro PC builds today for their overall compatibility range (when they're not scalped by collectors)

    Here's a PCem screenshot of the last thing you'll see.
