Тhis is a private(?) LZ algorithm. You can read this thread: https://forum.xentax.com/viewtopic.php?f=10&t=9481

I remember reading through that entire thread when I was first researching this bugger of a title, had a hope perhaps the lads over at the Xentax forums had been wrong, and that the PMCQ algorithim was just a fork of LZO. I actually managed to talk to Ekey (a very talented developer who's quite experienced with developing various decompression suites for a variety of titles), but he unfortunately lost his source code for his Sleeping Dogs decompression tool. I'm not sure if you'd be able to answer this but do you know why xtool might be reporting lzo1x streams? Is this just as simple as being an error on xtool's part? Honestly might try again to adapt his original decompression function (which we still thankfully have the source code for) as an xtool plugin, but given my lack of success in previous attempts I doubt I'll make much progress.
