Re: Old Packard Bell Machines
I think dns2k/dns2kv2 is the guy from from the RetroROMs forum who made a lot of patches that "add" stuff, but often with very poor emulation. I genuinely wonder how he got the PowerMate V to work anyway, considering I tried to add it once, and I couldn't get PCI graphics cards to display ...

Re: Dynamic recompiler and UNIX
I suspect this is your feature messing with operation, because to quote from another place: SCO UNIX with dynamic recompiler turned on - it (binary) gives error "Deleting deleted block" and closes down. I suspect it uses a jump to 0:0 to do something and fatals the emulator because of that...

Re: slowdowns in XT and IBM AT 286 emulation
- Fenix77: If the games run from a floppy, it could be the floppy emulation that slows it down. 86Box has more accurate floppy timings than PCem. But if it is the floppy slowing down the game, then the same should happen on real hardware.

Re: [BUG] System shock crash on launch on specific cases
Well, most sane operating system (not talking DOS here), trap the first page of RAM, so something jumping to 0:0 will raise an exception anyway, causing the OS to give an error message. I'm quite sure that's more desirable behavior than the emulator fataling.

Re: [WIP] Improving SB Mixer emulation
If the driver measures the time, and then determines the amount of memory to read based on it, and the measured time is off by one, I can see it reading more memory than needed. This would also explain why the extra sample has seemingly random contents, as it would simply be what follows the DMA-wri...

Re: [WIP] Improving SB Mixer emulation
The extra sample is probably due to an error with PCem's timers, as it sounds a lot like what I'm seeing when measuring the emulated floppy drive's RPM with FLOPRPM - with the code done right, it alternates between the correct RPM and slightly slower RPM which implies that sometimes, extra timer pul...

Destruction Derby for DOS slows down a lot under Windows 9x
This is on a Pentium 75, Award 430VX PCI, recompiler enabled. It happens starting from this commit: https://bitbucket.org/pcem_emulator/pce ... ba296c099e , before that commit, it was fast.

But 180k floppies are compatible with 360k drives - they only differ in the number of sides - 180k has 1 side, 360k has 2 sides. Everything else is identical.

Re: A&A palette bug
I remember that on the MAME forum, someone once wrote a (S)VGA sequencer test, that on real hardware, would under some conditions, sequence the colors off by one. I tested it in PCem, and it didn't do that. If this game sets up the sequencer mode that way, it could explain why this happens.
