Here. The file of your interest would be \NPEB00020\USRDIR\flog_ps3.fpg But I do not know its internal format, so I cannot help with that. If you want to extract pkg yourself, try searching for "pkg" "extract".
Xbox 360 version sprite files by JacintaB19 at 4:37 PM EDT on June 18, 2020
Are .MSF files the music files or the sound effect files?
As for the sprites, the PS3 version's ones couldn't be ripped. I have some sprite data files ripped from the Xbox 360 version if you'd want to take a look at them. I don't know about the Xbox 360 version's sprite format either.
Yes they are. You need vgmstream to listen to them or convert them to PCM WAV
It includes the music, SFX and dialogue.
