Inspired by benryves DOOM stuff I decided to fool around with it myself. At first it was just supposed to be a simple texture loader, but things quickly changed. So far I can load all the WAD textures and I can load one level at a time, just the data though, I haven't tried to assemble the level yet( it scares me...). I fugure there's no real reason to load more than one WAD or level at a time and even now the bare-bones app takes up 80 megabytes of RAM.
And now for some simple screenshots. Everyone loves screenshots.
This is level 1 of DOOM 2. It looks right, except upside down.
Edit: The JPEG format raped my pictures, I swear it doesn't blur like that.
