Rune Factory 4 Special mbundle file

Post by Appectedies »

Hello, I am having some trouble with the "sf30_mbundle" script and Rune Factory 4 Special.

I was able to use it to extract the contents of two other mbundle files from the same game, however when I tried to unpack the main bundle it gives me nothing but 1kb dummy files. I'm not sure if the main mbundle being over 4gb is the problem or not, but that is my best guess. I was using the 4gb version of the program.

Here is the offending file:

This format is a mess because it's a sort of collection of resources rather than an archive of files, the result is ever a mess.
If you have been able to reach a coverage ("coverage file 0 XX%") of above 90% that's ok.
Just focus only on the files that are big enough to have interesting content.

Thanks for the information, though it's a shame because it's at 0% coverage.

I managed to extract the main file with watto game extractor, the only issue is I have no idea how to put it back into an .mbundle file format afterwards.

Good news, apparently it doesn't need to be rebundled for the game to read it. Loose files seem to take priority.
