#+title: DOOM on Emacs

This is [[https://github.com/id-Software/DOOM][DOOM]] running inside Emacs via a native module. The port is based on [[https://github.com/ozkl/doomgeneric][doomgeneric]] such that only a handful of functions like DG_DrawFrame need to be [[file:doomgeneric/doomgeneric_emacs.c][implemented in C]] with some [[file:doom.el][Elisp code as glue]]. It uses the native Canvas API which is not yet part of the Emacs source tree, and currently available for download as [[https://github.com/minad/emacs-canvas-patch][patch]]. See further canvas links below.

  • Running DOOM

In order to run DOOM, you first need to apply the Canvas patch to the Emacs source and recompile Emacs. Then execute ./run.sh to compile the module and start DOOM on Emacs. You will need a WAD file which contains the game data. The file doom1.wad is freely available.
