Edit: Nevermind, I seem to have some other problem, I just verified this happens even with out GeDoSaTo installed. Though if any one has a clue and wants to chime in, it'd be appreciated.
So I'm having a problem, when I try to run FF8 (or FF7) with GeDoSaTo active, I get this message when the game actually starts (After clicking play on the launcher screen): "Failed to Create useful Direct3D device"
There is a black screen, a windows error box with that message, and the mouse is invisible. Hitting return or escape closes the screen out and returns to the launcher.
And to be clear, this is the Steam version. And I just updated to the latest GeDoSaTo.
