Known problems:

 - The D3D blitter is not compatible with Voodoo
   cards, or any other card that limits textures
   to squares or has a maximum texture size of
   256x256 pixels.

 - Any keys defined as inputs for the emulated game
   will work as such, even when they are used for
   e.g savestate slots.

 - When using the D3D blitter, if part of the window
   is off the screen, the image disappears.

 - One some PC's the mode indicators can crash FBA.

 - When executing some special moves on CPS 2 games,
   graphics priorities are wrong.
