Yes this game stores saves inside jpg files concatenating actual compressed save data at the end:
> binwalk save_1.jpg DECIMAL HEXADECIMAL DESCRIPTION
0 0x0 JPEG image data, JFIF standard 1.01 9137 0x23B1 Zlib compressed data, default compression
Actually many old Frogware games do that. And I think I've seen such trick in other games too but very rarely.
%appdata%\Games is not "hoarded" by just this game. It's used by several Frogware games, at least these ones:
- Sherlock Holmes: The Awakened - Remastered
- Sherlock Holmes versus Jack the Ripper
- Sherlock Holmes: Nemesis - Remastered
- Dracula: Origin
Including localized folders for those games.
In later games they switched to %appdata%\Frogwares folder.
