The guy asked for cheats not your opinions on whether cheating is good or not. Some people are genuinely not as good as you at playing games. You could have just answered his question instead of patronizing him by saying 'use your brains' or try pacman (in some ways pacman is actually more difficult than HOMM4 -- you actually need to use your reflexes and don't have all the time in the world for thinking).
Since after two pages of debating, there has still not been anyone to help this poor sod by just answering his question, here are the cheats (if you haven't found them already):

For all of you that hate cheating so much go protest outside 3do. They obviously are the ones that put the cheats in the game in the first place.
For the person that posted about Doom. Excellent point. I remember quake 2 god mode and haveing an excellent time slaughtering.
And for any of you that play AofE 2. There is a code that gives to a little monkey. That is the sweatest cheat I've seen in a game.
If someone is having fun playing the game the way they want why should you care? And give me a break on that money argument. If someone wants to waste $50 that is their problem and not yours. More than likely the person that paid $50 for the game paid a lot more for the computer to play the game on. Go yell at the federal government for wasting our money before you yell at someone else for wasting their money.
