Re: Dynamic recompiler

The Windows desktop is massively affected by the somewhat crap cache emulation. I would expect performance in actual applications to be a bit more modest.

This might be a cache issue. I can't test right now, but can you set cache to 'Infinite' and see if that makes a difference?

Re: Dynamic recompiler

I can't reproduce this, but it looks like you've hit some obscure bug of some kind. In any case, your machine can not emulate a 233 MMX at full speed, so I suggest you select something a bit more modest! Just as a final quick test, what does the status window (Misc -> Status) show for 'effective clo...

Re: Question about the audio

Not without rewriting the entire audio system, which will result in breaking anything which requires synchronisation between CPU and audio device. Even if this was done, you'd likely still end up with slowdown when playing MIDI, which varied with the speed of the emulator. Not worth it. In any case,...

Re: Question about the audio

No, because the audio emulation deliberately runs in sync with the emulated CPU. Hence it runs out of data when the CPU drops below 100%. The obvious workaround is to slow the emulated system so that it doesn't drop below 100%! It's a bit more like a SNES emulator or something rather than a traditio...

Re: Joystick Emulation

The joystick emulation is associated with the emulated machine, rather than the sound card.

If Windows has recognised your controller, then the joystick emulation should Just Work. Is the controller is showing up in Control Panel okay? (on your host machine, not the emulated machine)

Re: sound stutters on win95 and win98

CPU emulation is well over 90% of host CPU run time in most cases. Probably a few percent will be lost to sound + video through timer callbacks, but the main issue is that the CPU emulation simply isn't very quick.

Re: sound stutters on win95 and win98

What is the speed % displayed on the title bar? If this drops below 100% then sound will stutter, and you should reduce the speed of the CPU you're emulating. Given your host machine I can tell you that you have no chance of emulating a PMMX/233 at full speed.
