The only problem using a software program to do it for you instead of editing the hex file for yourself is that you're not learning anything. Say down the road you get a game you want to cheat in as well and there is no program to do what you want? Then you'll actually have to learn how to do the hex code.
For me, for this game it took me damn near an hour to figure out where my Cr code is. I finally did it, without asking for help, but the problem is not ALL Cr hex codes start at the 00 column. Mine actually started on row 0000F260 column 0C so I had to start my edit there and in row 0000F270 the 07 81 AF 01 part started in column 00. So don't look at the pictures and go "That's where mine should start too because that's where his starts."
Only reason I didn't need help is because I spent 9 hours over the last 2 days messing around with hex editing for final fantasy 13 and I still don't have everything 100% working. There's still 1 last problem. Easily fixable though. Anywho, if I hadn't already been learning this stuff, I probably would have made my forum account here just to ask for help. But I didn't.
