how do i start a ps3 game

no clue what you said

i checked. game folder is called BLUS31397-[Tales of Xillia 2]. in it there is folder called PS3_GAME, another folder called PS3_UPDATE and file called PS3_DISC.SFB. there is no .self or .elf file anywhere

how exactly do i start a game?

do i directly say boot game?

OR

i say boot ellf/self then i say boot game?

OR

i say boot elf/self only?
