I applied the patch to Diasgaea 4 Fuuka and Desco-hen Hajimemashita (by mistake) and its working, but with buggy text in some places. And if you go to the senate a bug will ocuur with black screen and missing textures.
It's possible that the expansion mostly modifies data files I guess.. and I'm pretty sure you will be missing a whole lot of textures by doing this hahah. Very interesting though.
4* If you want English cutscenes and Main Menu, you may overwrite your's Japanese "ANM.DAT", ANM_HI.DAT", "BG.DAT", "BU.DAT", "Dis3_0.dat" with US version equivalents (if you happen to also have an US version of the game)
When I try this, the game hangs on that first loading screen with the spinning prinny before the title screen. Default patch method. It works fine if I keep the Japanese files, though.
Selected directory: D:\D4JP\Disgaea 4 (JP)\BLJS10095
PS3_DISC.SFB has the right CRC: DF47E366, seems like you are using right version, continue...
EBOOT patching is on, proceeding to patch...(Backup will be made)
Found vanilla japanese eboot, patching..
Patching EBOOT failed, reverting changes...
START.dat patching on, proceeding to patch...
Unpacking failed...exiting
Another suggestion, try placing a game somewhere, so the path won't have spaces.
Like D:\D4JP\BLJS10095. It may be spacing problem, although I corrected it ages ago, but maybe somehow it's back..
EDIT: Tested and it seems to work fine for me with spaces... Oh, maybe you haven't unrared patch and used it out-of-the-box? You should unrar patch somewhere, prefferably on the same disk as your backup.
Try and report back
