The Commodore VIC-20? It can’t run Doom, but it likes to pretend.
This surprisingly ambitious little clone by “Kweepa” has eight levels, four enemies, five weapons, a whopping TWENTY sound effects, and a whole lotta eye strain. You’ll need a 35kb RAM expansion (THIRTY FIVE WHOLE KILOBYTES? Sweet jesus!) to run this on the actual hardware.
Grab it here!
