I mean, I've been running NES, SNES and GameBoy games on emulators (in Linux, natch) for decades now. Hell, I played through FF5 for the first time a few years back. Edit to add: I also run DOS games like Ultima Underworld, Master of Orion 2, etc in DOSBox; things are already pretty good, but I will point out two other examples to argue for releasing of source: Jagged Alliance 2 and NeverWinter Nights. Both games released for Linux, but only JA2 had a source release eventually, and it still runs, because having source gives you that. Meanwhile, I still can't go back and replay NWN.
