Place the extracted Wolf3d folder into your GAME Folder in your PSP (ie. SONY PSP(I:)/PSP/GAME/).

Copy the following gamefiles from your disk or CD.

AUDIOHED.WL6
AUDIOT.WL6
GAMEMAPS.WL6
MAPHEAD.WL6
VGADICT.WL6
VGAGRAPH.WL6
VGAHEAD.WL6
VSWAP.WL6

Same goes for Spear of Destiny Files (SOD). Also, make sure you're using the original files from SOD and/or Wolfenstein 3D. Other files such as modified ones or ones from pspdoom probably won't work.

Now copy the above files to /GAME/Wolf_3D/Files/(*whatever folder the game is)/ directory. In other words, if you have the Full version WL6 (Wolfenstein Full game) files, they need to be in *Wolf_3D(F) folder.

If you happen to be using the floppy version of the game, copy the contents of the floppy patch into the Wof3d_(F) folder, overwriting the original.

Depending on your PSP, make sure you're in the right mode of kernel (3.xx kernel, 4.xx kernel) in order for Wolf3d to load up.

Take into account certain plug-in's interfere with Wolf3d and cause it to not load up. Also make sure no config file is in any folder, same goes for save files.
