What about 320x200 and 320x240? I don't have a MS-DOS system currently setup to test it with, but I had done some testing in the past. It will sync to those resolutions, but it does framerate conversion for anything that is not 60hz. I remember also that it did lose sync during some of the sections …

Can you test it with PixPerAn at 70 and 75hz, probably at low resolution (640x480 or 800x600)? If it does skip frames you will see it immedieatly. So I tested it with PixPerAn at both 640x480 and 800x600 at 70 and 75Hz. It was dropping frames on all of them. I also tried it at native res (1600x1200 …

I still own it, if you would like me to I can hook it up and test whatever modes you would like me to. I've been using it in "Mame cabinet" running Lakka for a while, which converts everything to 60Hz anyway, but I can hook it up to something else for testing if that would be helpful.

Hey everyone, just wondering what the best sampling rate to use is for Tandy and CMS? I saw another thread where 27965 Hz was mentioned, but I could not determine if that was the optimal setting. Also, is there any advantage to using Nuked OPL for CMS, or is, as the name suggests, does it only do …

You could use a scanline generator much like this https://www.focusattack.com/scan-dl-vga-scanline-generator/. It should give you the effect you are looking for, though it is also going to reduce the overall brightness of the screen quite a bit.

There are a couple of FPGA boards out there with full C64 cores (MiST and Chameleon 64) but I don't know how accurate the SID implementation is. I have a MiST board and the C64 sounds fine to me, but I don't have a real C64 to compare it to.

How is refresh rate handled by this scaler? Does it let you output at the original refresh rate or does it force a frame rate conversion?

Well, PAL games don't run at 60fps, they run at 50. If you want it to play at 60 you'll need the NTSC version.

Are you playing a PAL release of the game? If so that would be why it is defaulting to 50 fps.

Not that I found. There were some files labelled Midi mapper in the Windows 3.1 install files, but I never tried Windows 3.1 on that machine. ESSCONFIG for DOS only seems to have MPU-401 settings for later chips, but not the 688.

I don't believe the ES688 has hardware MPU-401. I never could get an external midi synth to work with it outside of Windows.
