Psychedelia, by Jeff Minter of Llamasoft, is not a game but a “light synthesizer” – a program that turns input (either from a person via a joystick or keyboard, or from a sound input) into graphical on-screen patterns. Psychedelia was first released in 1984 and was one of the first “light synthesizers” ever made; certainly ever to be made available commercially; and it was the seed that led to the Winamp visualisation plugin craze of the late 90s/early 2000s, and to the evolution of light synthesizers or “sound-to-light” technology in general.
Ported by Chris Clark of Salamander Software and first published in 1984, Metagalactic Llamas: Battle at the Edge of Time is a straightforward conversion of the VIC-20 original, but with a couple of tweaks here and there.
The 1984 Commodore 64 version of Metagalactic Llamas: Battle at the Edge of Time was converted by Aaron Liddiment for Llamasoft and is pretty much the same as the classic VIC-20 original, except with better graphics and arguably better sound.
