What's new then in this version :

- Improve global emulation speed
- ISO file support but sound audio track are ignored
- Screen size 320x240 is now supported
(required for games such as R-Type)
- Add two new sound engines : mono (fast 22K or 44K) and
stereo (accurate 22K or 44K).
You may have to reset the game when you change between
mono and stereo, and save states may not work properly.
(few games are now fullspeed using audio mono 22K at 222Mhz)
- Zip rom files are now decompressed in memory (much faster !)
- Bug fix with D-pad (didn't work properly in previous versions)
