It seems much more capable then the other alternatives (Tsearch / Cheatengine) , Im not saying those are bad but

Now Ill jump to the questions:
I am currently playing a oldie rpg , Secret of mana 2 (Seiken densetsu 3), I have a little experience with memory editing but not a lot.
I can easily change some of the values (Gold, exp) but I'm wondering about how to start with some of the more complex factors in the game.
Would it be for say possible to edit the knights attack speed (Duran , ingame has a slower attack and slower recuperation from attacking compared to hawk the thief, or so It seems), How would I go about something like this?
Or something else Ive seen done in certain cheats for other games , say increasing the experience gained for killing a monster (Some of the cheats, just blatantly give you 9999999 experience on a kill however I find that to take some of the challenge from the game)
I don't know if I need a hold my hand through it explanation or just a few hints on how to go about it , but any help is appreciated.
Thanks again too for the great tool.
