DOOM has received yet another port, this time for a platform that was particularly popular in Hungary and many other European countries. A functional Commodore 64 version now exists, even though a similar adaptation of Wolfenstein 3D was once considered impossible.

We can play DOOM on an e-cigarette, printer, oscilloscope, pregnancy test, ATM, and even inside DOOM itself, but can it run on a Commodore 64? Production of the old 8-bit powerhouse ended only one year after DOOM launched in 1993, and although the computer was capable of minor miracles for its era, it was hardly an ideal platform for first-person shooters. Engineer and programmer Steve McCrea has worked on numerous Metroid games and the VR port of Resident Evil 4, but his current project may be even more significant: he is creating DOOM for the Commodore 64.

This is far from a simple port, and technically it is not even genuine 3D. According to McCrea’s tweet, the game is based on code from The Keep, a first-person dungeon crawler he created for the Commodore VIC-20. The VIC-20 was the Commodore 64’s technically weaker predecessor, although it reached stores only one year before the Commodore 64 launched in 1982. McCrea explains that his C64 version of DOOM uses ray casting within a tiled grid. Unlike The Keep, which resembled Wolfenstein 3D and consisted largely of a flat grid-based maze, McCrea’s Commodore 64 version of DOOM includes variable floor and ceiling heights as well as elevators. It also features doors that can be opened and visible weapons, neither of which appeared in The Keep.

The latest work-in-progress video is genuinely impressive and already demonstrates variable lighting and a skybox. McCrea says he has completed the levels from E1M1 through E1M8, but he is currently seeking help with the music. This would be the perfect moment to contact a chiptune legend such as Chris Hülsbeck or perhaps Jeroen Tel.

Back when we released Wolf3D I begged Id to make a C-64 version and they said it wasn’t possible.

Now I’m crying. https://t.co/qGQV0C7WSh

Scott Miller, founder of Apogee Software, which published Wolfenstein 3D, was also deeply impressed by the project. “When we released Wolf3D, I begged id Software to make a Commodore 64 version, but they told me it was impossible. Now I could cry,” Miller wrote.
