Basically RHIDE works with standard VGA modes and with VESA modes. There are 
problems with some video boards because of bugs in the VESA implementation, 
mainly in the routines that save/restore the video mode, looks like these 
functions are used only by few programs like RHIDE and hence they aren't very 
well tested.

About the crash got by RushFan357: Are you using the Allegro mouse?
