Also stumbled over another bug: If you set an alias to 640x480 to 641x480 the tool will instead display a resolution of 0 x 0. If you set it to 642x480 it will work.

Received the cables today and tested the 109xi, works like a charm. Unfortunately the 640x480 resolution still stays a hassle. Only get a clear picture with 800 width and that is not automatically applying due to a bug in VCS I guess (posted in the other thread). Furthermore I think that about 2 …

I should've read more closely what you posted, my bad. Regardless of your output resolution, have you ever just set the resolution to 640x400 manually? Ignore what VCS auto detects it at. And horizontal size to 800. Which version are you using? Is it automatically applying in your case? Check out …

Thank you, will test! I am not having any issue by the mode in itself. In this case I mostly would like to have a distinguishable difference between the normal Textmode and the 320x200 resolution. So that it can be scaled automatically and you don't need to manually switch the method of scaling each …

You could edit the CRTC registers directly to change the refresh rate to 69hz by adding a few extra scanlines of vblank or vsync into the video mode. But I am not sure if that will fix the root problem you describe. If you do want to try this out, check out the Tweak 1.6b tool, it allows an …

Before I was mentioning that the settings are not correctly applied. I stumbled over this again and I think I was able to narrow it down quite a bit. So if you are capturing something on exactly 800 Horizontal size, this size is not applied. 799 and 801 work. 800 is the Size used for 640x480 I …

There is no such thing as legit abandonware. It's just a term for items where someone thinks that it's unlikely that the owner cares enough to sue you. But that doesnt make it legal. So I am pretty sure that this link will be deleted as well.

For physical copies of old games, its Ebay, Ebay Kleinanzeigen (German version of Craigslist), and Facebook collectors group.

I will come to my issue at the bottom, but first up want to summarize, so that the thread can also help other people with different sets of problems: DOS has two display modes which show as 720x400, which is the Textmode, and 320x200, which is interpreted as 320x200 There is the "MODE"-Way to change …

I also had the issue in windows and even 800x600 (though to a lesser degree) but yeah, as I wrote in my original post I'm using a 160xi, though it doesn't really matter as long as it has ADSP though I have others too, 109xi should work just fine. the 200Rxi is an older series iirc but yeah I get …

The Datapath has a known bug in that at 640x480 @ 59.94Hz it will not display the bottom 2-3 lines correctly. The solution that worked for me was to set the refresh rate to 75Hz in Windows. Obviously that will not work in pure DOS but I am sure there is some solution which allows you to change the …

the adsp makes it so the datapath card locks onto the signal correctly, while it's possible to shift the image on some of the extron interfaces that's not really necessary, you can just position it correctly in VCS using the interface. Ah, alright. But can you tell me which model you use? For …

Checked other messages in this thread again, and seems like I am not the only one: I don't remember if I ever posted my solution in here but it's rather straightforward. I just use an Extron RGB interface with "ADSP" in the capture chain, that fixes the sync issue. https://www.extron.com/article/ …

Thanks, yeah, that sounds in theory what I did, just with some additional steps. I just tried 640x400, but that is cropping off a whole lot. And decimating it makes it look a whole lot worse for me. That said, I think my result with just downscaling from 720x400 to 320x200 and then upscaled via OBS …

And another, but different datapath related issue: What is your solution in setting the phase for higher resolutions? You cannot really move it completely out of the way, it seems like with will always leave some smudge. In this video I am showing the problem: https://youtu.be/_OEAfKZShmQ

Can anyone who is using a Datapath VisionRGB check whether or not 640x480 gives you a complete picture? I was just setting up profiles and noted that no matter what, 640x480 is always missing a few pixels at the bottom. You can move the screen up, but it doesnt give you the missing pixels. It's …

One other thing I noticed: You can set a shortkey for activating different resolution inputs. As I don't see a way to split between a profile for 320x200 and 720x400 I wanted to do that via hotkey. However it seems like the hotkey does not work. The profile with the hotkey (as only condition) never …
