They shall be. Cheats shall be hidden in the game, with hard combinations of buttons, and extremely hard conditions, like "beat the game 200 times", so you waste a lot of effort trying to get them in vain, and then you get really mad, so you seek the cheats in Internet. (already suffered it with "Destroy All Humans!").
Anyway... Have you got P.E.C. to work, striderhien? Or striderhiryu beated you to it?
