Saves are for the lazy, i.e. all side missions have been completed (for gold) before the start of the storyline (the first mission has been completed to save), which can only be completed at this stage, in more detail what has been completed and what else needs to be completed for 100% (not counting plots) is written in a text file in the archive.

Save only for the American version of the game (and the Russian version, which is also based on it)

The same will work for the PSP emulator (PPSSPP)
