LDR: class std::out_of_range thrown: invalid vector<T> subscript

The game might look for files that aren't required to run the game (for example, stuff used in debug environments) and not find them and still be able to run properly.
If the file isn't there, it's probably not needed.
This can or cannot be the case though.

Try not loading libfs at all, and start with libsre, libspurs_jq, libresc and librtc.
It does crash with an access violation, that happens with a hand full of games at the moment.
