I played the Steam version of the game (I don't know if it will work on a pirated version) with the Ultimate BATDR and Smooth Bendy 2 mod (saving should work without mods).
All items collected (upgrades, pipe upgrades, audio recordings, notes, memories and books
Joey (crazy ending available)), difficulty level "Hard". Here is a guide to the slots:

Wilson's Lab - All items collected (point of no return!!!).

Hideout. Foyer - Slot for activating the crazy ending.
All items collected, except for one audio recording and one memory (they
are at the point of no return, and since you can't leave it, you can't activate the ending).

Town - Slot for the Familiar Faces achievement. Before going
to the Town, I activated the trigger at the point of no return so that Mitli would appear.

This slot contains a mission with a box for Betty.

Laboratory. Tunnels - Saved before the point of no return,
to avoid a bug that prevented you from going up the stairs to the Vault.

Installation instructions:

1) press Win + R

2) enter appdata and press OK

3) go to the LocalLow folder

4) go to the Joey Drew Studios folder

5) then to the Bendy and the Dark Revival folder, then to data

6) copy the save and paste the folder

7) when the sign appears, press "Replace files in the destination folder"

That's it, you're done. You can check and play.
