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

Good job, you ran the game as intended to! And you didn't do anything wrong.
Though it would be nice if you could upload the full log somewhere else.
The game runs pretty far considering how good the emulator is. You might want to wait a couple more years to actually play the game, until the emulator is developed further and is able to run the game.
