Default Game Killer/etc hack Dragon Quest 8

I suppose the title would say it all; I'm looking for a root only hack that can add not just gold, but experience points or skill points.

Forgive my English, but I was hoping to get something akin to the Final Fantasy 3 save game editor, but, obviously, for Dragon Quest 8. I had heard Game Killer was up to version 3, but the highest I've found is 2.6 and had difficulty using it (I'm rooted) to do anything but add gold.
