Some Issues :

All Ports:
- Recode netplay feature, once core is not random anymore.

SDL Port:
- Low performance due to differences in surface sizes (internal and
  SDL), make both the same size.
- OpenGL code is awful, uncomprehensible, stupid and awful again.
  We must fix it.
- Support overscan in games like DQ5.

Windows Port:
- OpenGL, or Direct3D support would be nice (we have the source for
  OpenGL but it needs to be integrated into the main tree, any takers?)
- Windows port should be converted to Direct3D from DirectDraw 7.0.
- Windows sound code needs to be rewritten to reflect the SDL port.

Compatibility
- Game not working - Guikuden 1, Cu-On-Pa (and loads more)
- Graphics Glitches - Killer Instinct (black background), FF3 (Range Time Over
      and other sprite trouble), Tactic Ogre (Menus), Energy
      Breaker (mode7 world map), Super Aleste (incorrect opt in stage 5),
      Top Gear 3000 (DSP-4), lots of others...
- Special Chips - DSP1 (95% done), DSP3 (50% done), DSP4 (95% done)
      SA-1 (95% done), SPC7110 (Needs some core fixes and decompression)
      SFX1/2 (done?), Seta 11 (0% done),
      Seta 18 (0% done), BS-X (50% done).

Timing engine
- Convert counter to 32-bit. (assigned to pagefault).
- Fix 65816 timing and take into consideration cycle differences in
  8/16-bit mode, branches etc.

Graphics Engine
- Fix some windowing/subscreen sprite problems that are still present in
  the new graphics engine. Probably pagefault will have to do this.
