I have unlocked all of the achievements on these save files, not sure if they will load and pop, or if you have to do something but just be aware!
Budokai 1 Save has:
-All unlocked characters
-Story mode complete
-All tourneys open
-Some money (I think, not sure)
Budokai 3 Save has:
-All unlocked characters
-Most moves unlocked or bought
-Lots of money to spend
-All tourneys unlocked
Saves aren't much, but I figured why not upload something, I've gotten a lot and haven't really given anything back heh. Just rehash/resign and enjoy!
