This is the Deathmatch Levels from the Gameboy Advance version of Doom ripped using Kaiser's excellent GBA Ripping tool. The maps inside were organized by me, and I aligned all the textures, fixed a bug, and optimized it.
Kaiser, his program is most of the work! Technically, I should be in this!
about 2 hours if you include my purging of ALL Unaligned textures and bugs
