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.
