Load the savegame file into a hex editor and change the offsets 87.990, 87.991 and 87.992 to FF. Now you have tons of money.

Okay, for Lord of the Realms 1, there is a money cheat that is a bug in the game. First off, SAVE UP MONEY!!! Don't waste money on anything! Just spend a little to sustain your fief. When you have saved up over 35,000 crowns, trade with a merchant. Then just buy ANYTHING YOU WANT, but you must spend OVER 35000 to get more money. Just do this, and you will be getting whatever you want from the merchant, and making money at the same time!
