Got this save from my friend and thought I should share it as it is quite good and I couldn't find any other DWG3 save in the Forums.
This is a Platinum save, so you will get the following difficult trophies without having to grind or play the really hard missions. Online trophies will not unlock, and you must use a fresh save to get these trophies. The History missions must be completed on your own as well. There is no password.
Due to large instances of people being banned, the PARAM.SFO file has been removed. Use your own!
Trophies that will unlock (go to the gallery or complete 1 mission for these):
Leader of Humanity: Completely finish either of the story missions 'Those Who Understand' or 'Those Who Fight.'
Reformer of Humanity: Clear all story missions.
True Dynasty Warrior Gundam: Clear all missions.
Sound Collector: Complete the sound gallery.
Character Collector: Complete the character gallery.
Purebred Innovator: Friendship level of all characters reaches level 5.
Legendary Master Ace: Shoot down 100,000 enemies.
Order of the Nebula: Exceed 200 plays.
Movie Collector: Complete the movie gallery.
Bounty Hunter: Obtain more than 10,000 G.
