This is a step forward, but actually using DistroBox is confusing. I'm at the low end of an intermediate user here and don't see a direct way to get the .deb pkg.
Yep. I got it. The guide got me most of the way. Some things that I'm guessing are related to DX11 are still broken (mostly textures), but at least the game runs reliably now. Thanks for all the help!
