Path of Radiance Supports

[Jodeatre]

So i've been replaying FE9 recently with the intent to carry the save into FE10. So whilst playing I decided to look into things a little deeper like trying to get as many A rank supports as possible I cant see a way to get all of them as there isn't enough maps/space to take characters along in the last 3rd of the game as an example if you wanted A rank support between Tanith and Reyson you have to take them both along for every map once they become available. This got me thinking into how many I could theoretically get in a single playthrough. It also made me wonder if there were any working AR codes or other ways to edit the support values. After spending 2 days searching and trying different things and trying to puzzle out the most efficient way I decided to attempt to hex edit the values but after not hex editing for a long time I've basically forgotten how to or even how to go about finding how or where the support values are stored for FE9, so I was wondering if anyone had any information or just tips to find where the correct bytes are in the save or if they aren't stored in the save where they are located. Oh and I am using the NTSC version if that makes any difference.
