So I've been trying to run a few emulators in Devuan.
So far the only one I've got to work at all is Zsnes, which works perfectly so long as you leave the renderer (D) rather than any derivative that has an (O) in it.
I also can't apt install glxgears or glxinfo, nor run them obviously, so I don't know exactly what the path forward is here.
Civ 2 plays perfectly in Wine, and Zsnes I've got running full screen with hq4x filter, so Super Mario World & All Stars is beautiful! I'm really just missing Mario Kart 64 and Urban Terror, and maybe down the road Dolphin the Wii emulator if I find time on a box with better hardware.
But I can already do the most important games perfectly in Devuan. Thanks Team!
