I don't know about all the other math you have there, but I was able to make the code work with Nolan to spawn a brave sword with 0 uses just by adding the 80 to both parts of the code from the gecko database. So 04884ECC 80B60060 turned to 04884F4C 80B600E0.
This code also made it so Nolan made every item in the first slot blessed. 04884F50 27100080
I know I wanted all laguz to have SS rank, and figured it would be easier to share it for others since it took me a long time to keep going back and forth to add 80. I also included the new item codes for the items I wanted to use.
