The debug mode is activated with a different command line parameter
depending on what version of the game you have.
v1.0 -> -next
Once in the game, press [ctrl] [tab] [enter] to activate.
v1.1+ -> -goobers
Once in the game, press [lshift] [alt] [backspace] to activate.
Once activated, these are the keys you can use:
[tab] [Q] - Quit
[tab] [W] - Warp to level xx
[tab] [E] - Exit to next level
[tab] [T] - Debug info in memory
[tab] [I] - Free items
[tab] [O] - Map of level (only works in beta versions of Wolf3D)
[tab] [S] - Slow motion
[tab] [F] - Position info
[tab] [G] - God mode (no damage)
[tab] [H] - Hurt yourself
[tab] [X] - Extra stuff (???)
[tab] [C] - Statistics
[tab] [V] - Add extra VBLs (Vertical Blanking Signal -- this will do nothing
for most users except maybe increase or decrease
the game speed.)
[tab] [B] - Change border color
[tab] [M] - Memory map
[tab] [N] - No clipping (walk through walls)
(This works only in Wolf3D v1.0 shareware. This mode can cause
really bad things to happen to the game, including corrupting
itself, which is why it was taken out.)
