using the LGP extractor, it notices that the files are compressed and asks you if you want them decompressed. Say yes.
The PSX file are compressed too, I don't have a decompessor for LZS in my code and the offset is different by a few bytes.
Saaay, how's your mad programming skills? I could use help filling out some opcodes. I also have a newer revision on my HD that correctly parses some of the conditionals and the JMPxxx commands point to the correct address. I just reset SVN so I should be able to upload an update soon.
