DOOM: Squashware Edition is a rework of the Doom Shareware IWAD for embedded devices with restricted RAM and storage requirements. The goal is to open the door to more "It Runs Doom!" projects.
DOOF (Doom On One Floppy) is a subproject that uses it to build a version of shareware Doom that fits on one floppy disk (1.44 MB 3½" or 1.2 MB 5¼").
What you will notice:
- IWAD file size under 2MB
- Console Doom levels
- Restricted texture set
- Shorter sound effects
- Smaller font on the menu and intermission screen
- Simplified (for size) title screen and intermission screen
What you might be less likely to notice:
- Fewer animation frames and rotations on monsters
- Fewer animations on powerup animations and other items
- Shorter music tracks
Is a 2MB IWAD file still too large for you? The silent version removes all the sound effects and is under 1.5MB. Perfect for when running Doom on your hair dryer which doesn't have a speaker anyway.
Is a 1.5MB IWAD file still too large for you? The 1-level version removes all except the first level of the game, and is under 700KB. Perfect for when you just want to make a demo video of your port of Doom to run on a dead badger, and you're not really serious about actually playing the game all the way through.
