Experience the amazing SID chip music and sprite graphics of the Commodore 64 in Gamertro by Lethargy, one of the standout C64 demos released at Function 2020 in Budapest, Hungary (September 18–20, 2020).

This demo showcases the legendary sound and visual capabilities of the C64, blending chiptune-style music with smooth sprite effects that highlight why the Commodore 64 remains a demo scene favorite even decades later.

I’m running Gamertro on my Ultimate 64, Gideon’s FPGA-based hardware recreation of the classic C64. It delivers full compatibility while making it easier than ever to enjoy these iconic demos on modern setups.

If you love the Commodore 64, the demo scene, or retro computing in general, this is one demo you don’t want to miss!
