1. Write lf2.net(write 2 not in numpad) and all characters will be unlocked!
2. In C:\Program Files\LittleFighter2\LF2_v1.9c\data
Rename firzen_ball.dat to john_biscuit.dat and john_biscuit.dat to firzen_ball.dat This will transform Firzen Cannon to an Energy Disk, so you can get one Disk for just 5mp with Firzen compared to 50mp for John. Changing the Cannon to a Julian Soul Bomb is not recommended because when one Bomb explodes, all of them do so too and that would cause great damage to you and your teammates as well as your enemies.
