The decoding was done through the English release, but for some reason, not all files can be decoded successfully, and some garbage data gets left inside each file (that can be removed without any consequence). Incidentally enough, the ORIGINAL Japanese release has been decoded successfully without any issue, even though that was not the release used.
GARbro
Visual Novels resource browser.
Requires .NET Framework v4.6 or newer (https://www.microsoft.com/net)
Operation
Browse through the file system to a file of interest. If you think it's an archive, try to 'enter' inside by pressing 'Enter' on it. If GARbro recognizes format its contents will be displayed just like regular file system. Some archives are encrypted, so you will be asked for credentials or a supposed game title. If game is not listed among presented options then most likely archive could not be opened by current GARbro version.
Files could be extracted from archives by pressing 'F4', with all images and audio converted to common formats in the process, of course if game format itself is recognized.
When displaying file system contents GARbro assigns types to files based on their names extension (so it's not always correct). If types are misapplied, it could be changed by selecting files and assigning type manually via context menu 'Assign file type'.
