ratchet and clank in game name edit

ive found a way to edit ur name in rooms like on socom. other people may know this but ill post how for people that dont. ok go2 nite pr and find text. then put ur name. then press select on the Address 0x00847D74. then copy it any paste it into ur nite pr browser. then jus edit ur name. i cant find any way to add symbols like the buttons but u can do that in the rm name. jus scroll down to ur rm name in the browser and edit the rm name. for symbols it strts on i think 80 to 9f. maybe more im not completely sure but yea.

too confusing..

im lost
