24 bit monster HP patch

can you give me a clue as to what you use to do this? this stuff confuses the heck out of me wanting to put the data in moreso trying to find the hex program to do this.

Any HEX editor will do the work. Some have features that others don't have but they all edit hexadecimal data in the end. I use either HxD, WindHex or XVI32. I would suggest you one of the first two to start.

To use it properly, you can follow a tutorial...there is plenty on the web (like this one). Open your editor, then load a ROM (FF3us ROM in this case). You will have a clear distinction between the address (left) and the data (right). There is 16 bytes per row in the editor. You can now navigate the ROM and go to the good address. If you want to understand binary and Hex data, you can check this tutorial.
