I could not find such an archive on the Internet, I decided to get confused and make it myself. Here are the saves after each mission, so if you messed up somewhere - do not despair, you can take the save from here and calmly move on.
ATTENTION! Saves work only on a pirated (downloaded) version of the game or on a PPSSPP emulator, so if you have a disk version, these saves will not work for you.
