how do i start a ps3 game

i downloaded the latest rpcs3 emulator, ran it and it said 2 dll files are missing. i got them and i put them in same folder as emulator and then emulator launched

how do i start the game? the game that i want to play is:-
BLUS31397-[Tales of Xillia 2]

in the boot it says "boot elf/(s)elf file" and there is "boot game". should i first say boot elf and then boot game?

if yes then what is elf/(s)elf file and where is it? is it in the game folder or its like a bios file that i need to get?

i skipped the boot elf and i said boot game. i got the errors which are in the attached log.txt file

a popup saying "installing game data" showed and there was a green progress bar. when it finished another window opened with a black screen

please tell me how to start a game and what i did wrong
