I think we need a slightly better description of the problem you're trying to solve.
My interpretation of your original post is that you have a large number of files to compress, but many cores. You tried pbzip2 (Parallel BZIP2) and the resulting files couldn't be decompressed. Have you confirmed that the pbzip2 compressed files are decompressible by normal bzip2? The page for pbzip2 indicates that they should be compatible with bzip2 1.0.2 or newer. The problem could be that the game is using a bzip2 algorithm that isn't compatible with bzip2 1.0.2.
