Hacking EUR and JPN games

[neko_koneko]

I have a hacked 3.55 CFW PS3 slim with Multiman as a backup manager. I have some ISO folders with EBOOT files in them and I put my games in the PS3/GAMEZ folder like many tutorials say. First I used Atelier Rorona (which has folder name BLUSxxxxx) and that one worked. I also tried Boku no Natsuyasumi 3, a Japanese game(BCJS30010) and Katamari Forever a EUR game(BLES00658), and both did not show up when I started multiman. Just Atelier Rorona. How can I get Japanese and Europe games to show up in Multiman so that I can play them? By the way, I also have an Eternal Sonata disc in my ps3 when starting up multiman if that matters. I have tried both without and with the disc in my ps3 with no success. Any help on this will be greatly appreciated!
