A night of fun and nostalgia - playing with Vice, Commodore emulator on Linux. Available as a package simply named "vice" in official Fedora repository, 5.8 MB in size, is a relatively quick download.
Some useful settings on modern screens would be to increase the size of the display by using Settings -> Vic-II Settings -> Double Size; or use Alt+D to turn on Full Screen mode altogether. To enable Full Screen mode, I had to switch Settings -> VIC-II setting -> Fullscreen settings -> Fullscreen device to VidMode instead of XRandR.
Then, going through the list of repositories of C64 games and programs listed earlier, searching for more online and adjusting the list. Hoping to find some of the old hits. Finding Elite, Le Mans, Infiltrator, Laser Squad, Usagi Yojimbo.
