I've got a PAL Jasper with JTAG and am trying to get BlazBlue USA working.
The game is region locked to NTSC/U and NTSC/J. I've tried extracting the xex and region patching it to region free with xextool and reinjecting the patched xex into the ISO, then finally creating a GOD package with ISO2GOD. This didn't work (black screen).
I've also tried extracting all the files from the game and FTPing them to a folder on /Hdd1/ and launching the default.xex manually. This gets the initial 'Loading...' screen but then it hangs.
It does work apparently on NTSC systems. I don't really want to mess around with changing the region of my 360 just to get one game to work so that's not really an option.
Has anyone with a PAL 360 managed to get this to work?
