This is probably a list of already known issues, but there are issues in the 8088MPH demo (available here: http://www.pouet.net/prod.php?which=65371 with a technical explanation here: https://trixter.oldskool.org/2015/04/07 ... emulators/).
The part of the demo where it shows a technique for sprites, PCem skips it completely.
In the raster bar part of the demo, the resolution constantly changes. All resolution changes seem to cause an issue in PCem where it will resize the screen drawing area to only be the native resolution with no scaling. A possible suggestion could be to check for these resolution changes and automatically scale it.
The final part of the demo where the MOD plays through the PC speaker completely crashes the system.
There may be other issues which I missed. The configuration is attached.
My system:
Debian stable
6600K @ 4.2GHz

Re: Problems with 8088MPH
I tested 8088MPH already, Generic XT has skipped when showing 8088 Miles scene.
IBM PC has showing that but windows size is changing each frames.
Final part crashes too.

Re: Problems with 8088MPH
8088MPH requires exact timing which PCem just can't do. This is unlikely to be fixed any time soon.
Re: Problems with 8088MPH
Well, https://pcem-emulator.co.uk/phpBB3/view ... f=2&t=2923 has the same issue as the 8088mph credits - it´s about the prefetch queue, not cycle exactness. The credits of 8088mph work in DOSBox, however.
