Action Replay coding

First, my apologies if this is posted in the wrong place!
My quandary is this: How could I go about encrypting a decrypted action replay code?
I will admit this isn’t a GC issue, but I found a discussion on this topic in your forums. I’m trying to get a gameboy advance emu action replay code to work.

My issue is that only encrypted codes work on the game, and I need to change some of the code. The decrypted code is this: 0222DDD4 00000108
The last 4 digits are item specific. The code changes the item in the first slot of your inventory. 0108 is a herb. I need it changed to 0139, a key item that glitched from my game so I can’t continue without the cheat.

The problem is that only the 0108 is given with the encrypted version: 5B54C947 51F9D3BE. And I don’t know what portion of the encrypted version is the 0108 or how to change it to 0139.

So, I need to find out how to encrypt 0222DDD4 00000139
So that the emu AR will accept it.

Any help? Thanks a ton!
