Tactics ogre PS1 Game shark codes?

I beat the game once now I just want to have a little fun with it. I successfully made a level 99 gunner equipped with a rifle. However the stats are all 0 including his HP. I also put in the max stats codes and checked over too many times. The only code that worked was the max luck code. The others suck as STR DEX VIT MEN HP and so on are all 0. Any help will be appreciated.
