I have three different Doom applications installed on my Q, wanted to share...
-Versions-
DoomCE (almost fullscreen, slow to turn, buttons not to my liking)
DoomSPV (fullscreen, fast play, buttons not to my liking)
CellDoom (not fullscreen, fast play, like the buttons)

-Minimal Install-
I have (only) these files setup on my Storage Card as follows :
\Storage Card\Program Files\Doom\CellDoom.exe
\Storage Card\Program Files\Doom\doom1.wad
\Storage Card\Program Files\Doom\DoomSPV.exe
\Storage Card\Program Files\Doom\wmdoom.exe
\Storage Card\Program Files\Doom\DoomSPV\doom1.wad
The additional DoomSPV folder and doom1.wad are there because thats where DoomSPV.exe looks for the WAD file. I could have placed celldoom.exe and wmdoom.exe into the DoomSPV folder if I wanted so as to only need one copy of the WAD file (but I have plenty of space on my card).
Most of the downloads include other files when you unzip or install, the files I have listed above are the only ones required.
