if you have the source to those programs, and are willing to (sometimes significantly) rewrite parts of them and recompile (see: wayland, for example)

The amazing part is that you don't need to do this in windows whether you have the source or not. I am a linux user, but for all their faults, Microsoft got their backwards compatibility stuff right. Something that the oss world, on average, needs to be convinced it's a desirable thing.

If it uses SDL (99% of the libre games), you don't have to rewrite anything.

> 99% of the libre games

i.e. much less than 1% of all existing games.

SDL was born from Icculus to run commercial games without issues on X/GL or whatever. So, it's actually a NOT in your clause. More like a 99% of the existing graphical games modulo some oddies with Ogre3D and friends.

At least in order to be playable under Linux. Said this, the 99% of the games from that era will run perfectly fine with OssPD->Pipewire (install OSSPD, just run the game) and 32bit SDL1 libraries.

Unreal engine uses SDL, so more than 1% of games.
