It's very simple! Type tieftrnr.bat and it runs!
When you run it, it gives you the keys you can use
and a description of the cheat.

type tiefcht.com  /U to unload it from memory since it's a TSR.

For more information type tiefcht.com.

BTW: Registration is $10,000 US for each cheat. Please
deposit it into my Swiss Checking account or send it to me
in small unmarked bills. Sorry no checks, pennies or credit cards
Please.
