Utility description

This program allows you to open an NES rom and type a game genie code. The change is PERMANENT, so be sure to make a backup before you start adding cheat codes. The program converts it to a hex address and puts a value into it. The codes become permanent as soon as you type them in, no need to save. Be careful of typos on 6 letter codes, the 8 letter codes have a compare value, so it will write the value to the correct bank on mcb1 and mcb3 games
