I could be wrong, but that reminds me that there might be some item or something in Wolfenstein 3D that causes a border to appear.

There's also a cheat code for it, but I don't know if it's for the overscan border:

It's the overscan border. Not a very useful thing, IMHO. I seem to recall they used it to flicker the border when you picked up a bonus, but I'm not sure.

Agreed, but I thought it was worth mentioning as a counterexample to DosFreak's assumption that no VGA games use overscan borders.

Keen uses VGA too....I think...gotta go check.

At least some of the Keen games are EGA, and I don't think any of them are more than 16 colors.

Finally got some time to work on this one. Not enough to make the entire thing working but I've tried Qbix's suggestion. Anybody cares to test and comment this one? The border will only work in surface/fullfixed modes were you actually have an overscan area. This is not a replacement for my previous patch, I am still working on the full patch.

It worked only with fullscreen 640x480 / surface. But so strange.
Look at the screenshot below.

probably a 320x200 game then.

Yup, Crystal Caves is 320x200. But it worked with other resolutions as well. Did you set fullfixed=true?

fullfixed value does not exist in the latset cvs. 😀

Doh! Good timing. So, how do I get the effect of fullresolution=1024x768 and fullfixed=true with new implementation?

As far as I can tell, just say fullresolution=<what>x<ever>

This implies fullfixed now, it seems.

mm mortal kombat I ? dont have a screenshot sorry

That is correct.
fullfixed=false => fullresolution=original

Updated to current CVS (that patch still should work), tried fullresolution=1024x768, and got the expected -- small image in the middle of the screen surrounded by very thick (all the way to the edge) red border. Probably need to limit the width of that border to 100 pixels or so -- it gets too distracting.

I've uploaded new version to SF. This one has limitation that it works only with surface rendering. It also requires fullscreen mode to be bigger than the game video mode (it is actually ovescan), works just fine in window mode by extending window accordingly. Very cheap performance-wise, looks quite good, easy to maintain unlike the old version.
I am planning to extend it to other rendering modes. I don't want to reimplement blending ovescan inside the image, it was too hacky before, it's really ugly with new renderer. Maybe some stippling hack like the one I had in paletted modes but that's not a priority.

I hate to bring back an old thread from the dead, but how does one enable border colors in the current DOSBox? Is it even possible?

I'm afraid not.

I had thought about a patch that flashes the whole screen in that color (in the distant future).

I wouldn't consider that an optimal solution, as some games may use border colors as a persistent notification.

I've always felt that a piece was missing from DOSBox without this functionality, although I do realize it's hard to emulate cleanly.
