Nope Maximum what can be achived - the first "Loading..." screen, where everything hangs.
No luck messing with 1.60 Jap Update either ...
Seems like a dead end.
For anyone who interested - almost every file in jap and US version is identcal - the biggest difference - START.DAT file, which contains some textures and texts. US Start.DAT has 15 more files then JAP one (when decompressed).
This is correct. The JAP Start.bin contains 450 and the US Start.bin 462 files. How do you repack them to complete .dat files? I use NISUnpack.jar to unpack it but I don't have any tools to put them back together. Here is my suggestion:
You use the japanese version of the game as the base version and replace every data in the every dat file with the english ones if possible. You should get a "more translated" version of the japanese game. It's not perfect but I think it whould be playable. The other way around with the english as base will not be possible.
How do I put the unpacked files together to .dat files?
The same question, that bothered me. I couldn't do it. If there could be a way, then with trial and error we could possibly create something.
I have tried using a japanese version as a base one, and replace only US Start.dat. Theoretically, as US Start.dat has more files, there shouldn't be a problem, but in practice we have a never-ending loading loop
For the japanese version of Disgaea 4 you have to download the Caravan release (because it runs on cfw 3.55). Do not use the Asia release (ofw 3.66). I can give you mediafire links for the japanese Version if you like?
If it's possible, keep us informed about what you're doing - I can jump in and help
Oh, I can say - I conquered black screen so far:
1) Grab Japanese version as a base - BJLS10095
2) Replace START.DAT (BJLS10095\PS3_GAME\USRDIR\data\START.DAT) with an US equivalent one (BLUS30727)
3) Game starts, reminds about update (ignore it, as it's 3.60), - game goes to loading screen, few minutes it loads something (external HDD blinks), after a few moments HDD stops to blink, but the "Loading..."
screen continues infinitely
It's the closest I could get, trying diffirent variations.
.DAT files can be unpacked via NISUnpacker, and further decrypted with NISDecomp.
Good luck, I'll try to play with asia version too.
