Well, there are a few ways to crack levels.

-Hack using hex, or whatever

-Use JCSBak- a program idntical to JCS except you can open it up wiothout a pass word. THen go in and change the pass or something like that. From what I've heard, editing it can unstable. Just use it to crack passwords then go to normal JCS.

-Use a little program called depas. A dos proggie, my good friend Slizer made it back in his JJ2 days.
