Gaming Change PSP's region?

[synce]

I got the Japanese version of Tekken 6 playing on my PSP but all the text is in English with no option to change it. I faked the region to Japan but it didn't do shit, is there anything else I can do short of buying a Japanese PSP?

I was gonna say something about the Wii but really there's no excuse for my stupidity. Your solution worked and now if you'll excuse me I need to kill myself.
