Hi All, Regarding Simcoupe.
What I'd like to see implemented is the 'screen off' BIT on port 254. Programs that turn the screen off to switch modes, or use screen area as a workspace, look so messy when the screen *isn't* being turned off. Flashes of crap look terrible!! Wouldn't it be possible to point the emulators screen to some blank & black dummy screen when this bit is set? I don't think the extra 'speed up' is that important, just the prevention of messy mode changes Etc. Still on Simcoupe. Alan, you say the PIC's won't program correctly under Win32? Well, I don't know about NT but my Asteroids emulator uses a re-programmed PIC timer to force 60Hz refreshes when users' monitors are refreshing higher. It seems to work fine... If anyone's interested the source is available: http://members.tripod.com/~asteroids Also, I've seen some 80x86 code that'll throw the VGA into a 50Hz 320x240 Mode-X mode. Obviously you need a monitor that will sync too. It works on my system, with a dead cheap monitor and under Win 95 too. Would make Simcoupe very nice if it could refresh at the proper rate... Chris.
