get back old win3.1 frame?
Do you mean a Windows 3.1 theme for Wine? I've seen Window XP themes, but not Windows 3.1. Just looking around, the closest I found was
But this is a Windows Blinds theme and not msstyles, and there is no way to convert. A wba file (windows blinds) can be unzipped by 7-zip if you want to create your own windows msstyles and use those resources as a starting point, but that might take a while.
If you find one, let me know, I'll include it in my file systems so the user can easily turn it on with WineCfg.
actually old wine does support win31 theme/frame natively:
last wine release(20040309) with win31look:
Unfortunately Boxedwine can't run Wine that old, the oldest one would be Wine 1.4 because that is when they implemented the dib driver that can draw everything to a bitmap (fonts, lines, etc), then all I have to do it take that bitmap and give it to SDL. The best bet for a particular look would be to find a msstyle theme.
