Yeah but the problem is that the file you provided is out of the standard and has an additional index table not referenced anywhere.

The format of RPA is simple, there is the magic string "RPA-3.0" followed by the offset of the table and the key.
The index is completely and correctly read by the script (pickle.bms).

Then there is another index at offset 0x00271bf5 without any offset or other information for locating it, therefore I have no way to go forward.

Example of the first bytes with the duplicate "Made with Ren'Py":
Code:
52 50 41 2d 33 2e 30 20 30 30 30 30 30 30 30 30   RPA-3.0 00000000
30 30 32 37 31 65 33 35 20 34 32 34 32 34 32 34   00271e35 4242424
