DOOM has been run on a multitude of devices – if it has a screen, then DOOM has ran on it! With this being the case, why not have DOOM run on the trusty 8-bit micro, the Commodore 64?
As you can see from the video below, that is exactly what we have here – a DOOM tech demo going by the title of RAD-DOOM which enables gamers to play DOOM on their Commodore 64 via the RAD Expansion Unit by Frenetic.
The RAD Expansion Unit contains a Raspberry Pi that takes the role of a CPU replacement for the Commodore 64. The graphics are still rendered by the original VIC-II chip. All technical details of RAD-DOOM can be found in Frenetic’s GitHub repo.
The gameplay starts off with keyboard controls, with the 1351 mouse control enabled later on. The special settings menu is visible from time to time where graphics rendering options and screen presets are available.
It’s amazing (and darn awesome!) what is still possible on the 41 year old 8-bit computer! Long live the C64!
