I have also modified my game to make all monsters infight and IDKFA not
to give keys, though this reqires manually editing your doom.exe file as
follows, which is the way I intend this patch to be used.

**FILE MODIFICATION**

Search for:39 CA 75 1D 39 EB 75 0C
Replace   : "  "  "  "  "  "  " 19
(infighting enabled - crucial for this modification as E3M1 is 
impossible otherwise)

Search for:B9 06 00 00 00 8D 42 44
Replace   : " 00  "  "  "  "  "  "     
(no keys in IDKFA mode)
