Hey there, didn't know if anyone knew yet, but you can get the US DLC for Dissdia Duodecim 012 working.
First off, YOU MUST BE RUNNING 6.35 (6.20 Non-Permanent or Permanent works too) Pro-B4 OR 6.20 TN-D Permanent AND you must be using the USA version of Duodecim.
I use 6.20 Permanent (just upgraded recently from PSP 2000 CFW 5.50 Prometheus-4)

Installation instructions here. ^ Install this first before you go further in this post.
Secondly, Go into the Recovery Menu, and under the Advanced option, turn NoDRM Engine OFF.
Third, insert this plugin into seplugins, and enable in it game.txt ms0:/seplugins/nploader.prx 1

You'll have to find the DLC pack yourself, but once you have it, extract the ULUS10566.rar somewhere you'll remember
Stick the ULUS10566 folder into your PSP\GAME, and get rid of any existing DLC you may have. Run the game, enjoy your DLC.
