Games don't tend to have subtitles like you might get on a DVD or your anime downloads.
Game text then forming the basis of a major aspect of ROM hacking (text hacking, and as you might imagine also quite important for translation) and comes in thousands of different formats, though a few main overall approaches.
1) Normal text engine
2) Text as graphics
3) In the case of video then subtitles/captions there might well be a subtitle engine not too dissimilar to that seen in DVDs and anime downloads, they might be burned into the video itself, and regardless they need not be the same as the rest of the game uses. Some hackers will so a "soft" sub approach rather than edit a video where the unhacked base game does not have anything.
I cover text editing quite extensively in https://gbatemp.net/threads/gbatemp-rom-hacking-documentation-project-new-2016-edition-out.73394/ if you do want to go further there. Not sure what exists for unpacking PS4 isos and whatnot, nor whether there are existing tools to handle common compression types.
