I figure you may know about LZ compression. It's very fast and reliable, however there are many implementations of it (and thus brings my question to light...)

I've seen a special implementation of this compression in Konami games, more specifically the Beatmania series for the Playstation. I want to know if anyone has familiarity with this format, and I would also like to know how this LZ variant works, if you've seen it before.

I have the SLPM files for the involved games, however I realize that distributing those is illegal. But I have a compressed and uncompressed data table for comparrison:

If you could provide any source code as to how to get from the compressed version to the decompressed version, I'd *very* greatly appreciate it.

Thanks for the consideration.
