BlastoUt is a simple command line tool which can extract the files from the various Blasto.dat files found on various Blasto PlayStation game discs. I haven't tested it with the demos that are floating around but I don't see why it shouldn't work unless they changed the pak format mid format


Download the zip below, extract the files, then in a command prompt run BlastoUt giving it the vol and where to extract the files to. It will then list the files contained within, where they start and their size.

After listing the contents, it will then proceed to extract the files. If the destination directory or any sub directories do not exist, they will be created.

The download contains the source and binary of BlastoUt.exe. Unlike most other things on this site, the program is written in C# and therefore requires .Net Framework 2.0. If you have an anyway decent/recent computer, you probably have it. Windows 7 and 8 include it automatically. If it doesn't run, that'll be what you need.

Just to head off any questions, I have no interest in making one myself. However, the source code implicitly documents the very simple dat file structure (except for the separating line between directories) so creating new dat files is just a matter of reversing the exploding process. You or anyone else is free to use any parts of the code which may help them create such a tool, but again I will not be.
