wintermute has emerged from these boxes the port of Doom for Nintendo DS and a string of updates to perfect the result. This new version fixes a problem mainly freeze (which occurs when the volume of sound effects SFX was modified) and adds a keyboard when editing the name of backups.
Obviously you will need the original WAD files episodes of Doom (Doom, Doom II, Plutonia, TNT, etc.). Which you want to play, to be placed in the directory of homebrew.
