Posting up this save (it is from Gamefaq with a bit of progress from me) to help anyone playing this game out. Doing a few things to trigger trophies will unlock most of the trophies (ie, cancel 1 action to get 1000 cancelled actions and so fourth).

I've tested it and it works with Xploder, I ran into a few freezing problems but when you save over the file it works flawlessly (you need the free Asagi HD DLC).
Everything is unlocked, X-Dimension, Land of Carnage, etc. Recommended to play through the game once and then use this save to aid you in attaining more trophies and saving hundreds of hours.

This save is for the US VERSION of the game, I do not think it will work with Region swapping because each Disgaea 4 game has a separate trophy list. However you are free to test and report back here.

If you can make progress on the file for the titles or ship parts please repost any progress you can make. Or if we get someone who knows how to hex edit *fakeshadow* maybe they would be so kind to attempt to mod the save to give up all items/grades/symbols and/or modded stats.
