I don't think I'd need to edit the box itself because I'm replacing the P with a "il" diagraph. "P" should be a value of 51 and the "il" diagraph is 8A. Based on your findings, I'm still looking for that, unless its different. Also, I'm using a headered ROM.
Edit- Once I removed the header, I found it. The G and the P are seperate from each other which makes no sense. However, now its fixed.
As for the Magazine, its current name is Lustful Lali-Ho in current translations. I kept it as Magazine in the item name, although I might change it in the description. Unless you have a better suggestion.
