a couple of the supported titles are pretty weird, but I'm at work now so maybe not so much. Doom ultimate and Doom II use dosbox in windows. I hope they're us

a couple of the supported titles are pretty weird, but I'm at work now so maybe not so much. Doom ultimate and Doom II use dosbox in windows. I hope they're using a linux version of dosbox instead of running dosbox on top of wine. That would be an emulator runnning on top of an api compatibility layer. Quake has an open source release and an official linux release (although it's probably pretty hard to get that running on modern distro)
