Well, yeah, because at that point they're hooked into the Windows Multimedia timer system. > 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.

I'm willing to go for 60Hz refresh, if the PC can make sure the emulation runs a 50Hz frame's worth of processing in that time. BTW: Currently, the plan is to use DirectX for everything, and to port things over to C++ slightly (for non-time-critical stuff). Oh, and I'm currently writing a new VL1772-02 emulator, that will have two modes - fast, and precision. Precision will have support for accurate timings - even down to emulating the spin-up of the disk, index pulses, and register-update latency - and everything that Fast has. Fast will have support for Read Track, and support for protected disks (which have physical side vs. address side, physical track vs address track issues). The plan is that you'll be able to do track-dumps of existing disks and put those directly onto the PC, and it'll handle it all quite happily (fingers crossed). Simon ps. Whoever's archiving... can you edit my MS email address out? I could do without the spam.. and unfortunately, jumper's down, Nessie's down, and Hotmail isn't sending out email...
