Infos

Doom clone derived from original ID Software sources and enhanced (SDL support, bugs correction...). Doom is the sequel of Wolfenstein. It is working quite well on 8bpp framebuffers; for 16bpp one, a bug has to be corrected in i.MX framebuffer (ongoing).
PrBoom is integrated in Buildroot on latest SVN snapshots. It needs SDL, SDL_mixer & SDL_net. Video was taken on the new LCD. Runs at full speed in 320x240 with only ~40% CPU usage in 8bpp mode.

Install

• Launch Buildroot configuration:

 $ make menuconfig

Package Selection for the target  --->
    Games  --->
        [*] OpenTyrian

Activate OpenTyrian package (it will autoselect SDL and SDL_net). Then, exit and save your config. Re-Build your rootfs:

$ make

and reflash it

Launching

• If you have a 320x240 display:

 # /usr/games/prboom -width 320 -height 240 -nosound &

• If you want some sound be sure that ALSA is running, with OSS emulation loaded.
• To change screen depth (default 8 bits), ex:

-vidmode 16bit

Troubleshots

• If SDL is complaining because it can't find any mouse (Unable to init SDL: Unable to open mouse) then, before launching the game, do:

 # export SDL_NOMOUSE=1
