[Solved] ParaParaParadise (Arcade) *.gcz (Texture Files)

[pm41224]

I'm looking to extract assets from ParaParaParadise's .gcz files that lay within the program CD's files. Is it possible? I'll provide sample files if need be.

Here's the first few bytes of at least one of the files, with the first 50 bytes highlighted:

BUMP: Here's a few sample files. Their size will vary wildly.

Im not able to extract anything but this viewer does show there are several textures within your .GCZ

This is what the Hex view looks like.

Maybe its just missing its header ?

Looking at the .gcz files in the hex editor, it's clear that there is no header in the .gcz files, at least in the first two or three bytes. The headers in all of the .gcz files are wildly varied but "GC" is always at the fifth byte. I'll provide an example header just to give you an idea of what I'm talking about:

EDIT: In case you can't see the picture, the first few bytes are highlighted in the hex editor to show what the "header" (or lack thereof) looks like.

QUICK BUMP: I'm suspecting that these may be compressed files within compressed files.

EDIT: I also suspect that this may be one of those "obfuscated archive" cases like I've read about on this site.

The file is LZSS compressed. The picture is 16BPP format.

Put plugin to Noesis\plugins\python folder.
