Editing roster tool for NCAA Basketball 10 (PS3)

Hi fellas. We can't change players class (freshman, sophomore...) in the game, that's sucks for dynasty. Since there is no NCAA Basketball 11. Anyone can help my to create an editing roster tool for PS3? I already extract roster file in data1.big. There is 2 files : nba_ng_db.db and nba_ng_db-meta.xml. I can send those 2 files by email if someone want to help me. Regards.

I upload the 2 files here : http://rapidshare.com/files/444955371/nba_ng_db.rar
I think that nba_ng_db-meta.xml must be decompress before. Someone good for doing that?

unfortunately, I dont think I can help you out here....it would require finding the 1 value for all the players.....especially since I dont have the game to compare to. Sorry.

So is it possible to just unlock the possility to change class of players by changing something in these files?

no, not really, it would have to be found along with all ratings and other variables
