yes i did but i cant find how to increase lvl. I changed MyHP to 930 from 93 to win this fight but when i enter fight HP is again 93 even if player stats show 930 :|
don't change the lvl (you can't with this save editor, but it takes effect about your next lvl boost anyway)
find your character, should be 6 on the list
(replace 10 with whatever number you want, 10 is a decent boost, 100 will make you overpowered, so bear that in mind)
type 10 to MHP to add 10 Max hit points
type 10 to MMP to add 10 Max Magic points
type 10 to ATK to add 10 to your Attack (100 will make you one hit kill everyone)
type 10 to DEF to add 10 to your Defence
type 10 to MAT to add 10 to your magic attack
type 10 to MDF to add 10 to your magic defence
type 10 to AGI to add 10 to your Agility (improves either your chance to hit or dodge, I don't remember)
type 10 to LUK to add 10 to your Luck (not show how this is applies to the game, probably dodge)
MyHP and MyMP are your current HP/MP change them to match what you entered for MHP and MMP, to make them stay at the values you want
