I analyzed it with a Hex editor, but it's hard.

I found an unknown programming language on the Hex editor.
Many files are inaccessible.
I don't know if unpacking is possible with bms script.

That's just the contents of the Make file as the header suggests and is the entire contents, if you need help extracting files from an archive you'll need to most that as basically all you did was extract one file manually.
