This build is the same as early access 3 but with the new cinematic audio modding features.
Open the hidden menu by pressing F3 at the Main Menu screen, then select "Generate audio modding template". The game will then create the required folders, and empty .json files for each cinematic in the game directory.After generating the template, none of the cinematics will have audio. Since they will load the empty .json files instead of the default audio.
The game will also generate a guide at "mods/audio/instructions_audio_mods.txt", which explains the system in greater detail.
From now on all of the cinematics will be unlocked while in the debug mode.And the memory menu also has a "debug flag" option. When enabled it forces all cinematic stages to wait for input before continuing, even transitions.
Note: I probably can't allow any comments linking to downloads for audio mods. Patreon might not be too happy with links to potentially copyright infringing material.
