Final Fantasy Hacktics

To introduce my self im a tactis fan from swiss, sorry if my english is a little bad. I beat the game a few times and its been some yrs since i played it. So now i strted a new game on my pc using a emulaor and wanted to do a job points hack using cheat engine but for some reason i couldnt get it to work so i looked on you tube and came across this site. I almost peed my pants just by reading some of the posts... i would love to play the game with new characters and weapons with diffrent storyline or the same just something to spice it up harder monsters to beat. But looks like u guys do everything here imaginable. So my question is how do i do this???? i looked at some tutorials but i didnt understand it much... is this just for the playstation hacks or can it be played on a emulator??? is there a .bin file that i can download and play or how do i get these patches to work??? please help...sorry for the englis
