Calico
,→Features: -iwad, not -file derp
==Features==
Calico allows playing the Atari Jaguar version of Doom when provided with either a {{wp|ROM image}} (legally obtainable via use of a backup device), or the extracted [[IWAD]] file from inside it (these files should be named {{c|doom.jag}} or {{c|jagdoom.wad}}, respectively, in order to be autodetected - use of the {{c|-fileiwad}} [[command-line switch]] is also supported).
Calico utilizes [[render to texture]] via {{wp|OpenGL}} to provide a scalable window with optional hardware filtering and support for variable [[aspect ratio]]. The latter is particularly useful for authenticity's sake, since different television sets displayed the game's signal differently.
