A program that lets you directly edit memory space or hex code... useful for cheating in games that someone else hasn't written a cheat program
or character editor
yet. Presumably also useful for cracking registration on shareware, and that sort of thing.
More useful is the pagan version, that lets you modify hexes you have placed on someone or that someone has placed on you. Think about it.. someone places a hex on you that makes it so that you never find money on the ground. You edit it, and suddenly, you ALWAYS find money on the ground. Pretty spiff, wot?
