- added a new option in the pce.ini file
´[misc] screen_resolution´ to display the current
screen resolution of the PC-Engine under the FPS counter
- moved the ´fullscreen´ option from the ratio menu to
the zoom menu, like that it´s now possible to select
fullscreen stretch while preserving the aspect ratio,
this can be useful for exemple for those who have
a 16:9 wide monitor
- fixed the slow down problem when the Supergrafx emulation
was enabled
