When I visit the GitHub link, it says that your branch is even with tesnos' branch. Are all your modifications to the source code not on there or something? Just a bit confused.
Are you able to put information about nogc patch in the README?
As a lot of people are upgrading to a higher FW, not realising that they may be unable to use the gc on a lower firmware.
Regarding Persona 4 Golden, here's a tip for anyone wanting a challenge.
The P4G save editor is written in C#, therefore can be decompiled with Jetbrains dotPeek. All the offsets are listed within the reversed code.
Just posting to confirm that replacing P4G's eboot with either molecular shell or vitashell enables access to the decrypted savedata for backed up games (using Vitamin)
