Maybe it will be useful to someone.
I created a small script for the Cheat Engine program, this script opens the entire game gallery. Tested on game versions 1.9.6 and 1.9.7.
Activate the script when you are in the game's main menu. After that, open the CG menu and you will see that all menu items are open and you can view any scenes.
Note. The script does not change your save game. After disabling the script, all CG menu items will return to their previous state.
