AR2/Max or GS2/3 codes for japanese games
 

Anybody know a good website to get AR2/Max or GS2/3 codes for japanese games?
I know gamefaqs has some, but not for the games I want.
I also know Datel makes a jap version of AR2, but it's in japanese (katakana) so it's no good. I tried searching the codejunkies website, but couldn't find any jap ps2 codes.
Any help would be appreciated, thanks.
