Amiga

The Amiga home computer platform was fairly popular during the late 1980s and 90s, but it was widely considered that it was not possible to do a game like Doom on this platform due to technical restrictions of the standard Amiga graphic chipset, which was built to do scrolling sprite based games, not pixel-based rendering.

Ports
Quickly after the release of the source code, several people jumped on the bandwagon and ported Doom to the Amiga. This resulted in several different ports which competed for the Amiga userbase. In recent years, several more modern ports arrived on the system, derived from the PC versions. These new ports also include support for Retargetable Graphics, which allow standardized resolutions and true colour screens to be available through common SVGA adapters. The two most common API's used in Retargetable Graphics are Picasso96 and CyberGraphX.
