In Dark War, I type Dipstick to enable the cheats but no matter how many times I type a code whether with \ ,CTRL or any variation, none of the cheats work, only the dipstick command. I need help with this.

I've tried the cheats again. the appear to work but either some of them don't or their functions are not at all obvious e.g. FUN, Engine Killing Gibs (the best one next to warp levels).
