    Got a bunch of old .Z compressed CD-ROM images I made for pcsx reARMed and would like to test them on PC.

    Unfortunately pcsx reARMed on RetroArch can't recognize them.

    So i do a 'file' and they say they're zlib data.

    So I tried pigz/unpigz (a zlib compressor/decompressor) and for all my game images it yields
    unpigz: warning: test.Z: trailing junk was ignored​

    and creates a file 2352 bytes long.

    └──╼ od -h test |tail -4
    0004400 0000 0000 0000 0000 0000 351f 481b 5370
    0004420 2e74 0000 0000 0000 0000 0000 0000 0000
    0004440 0000 0042 0021 0056 0094 00a1 0000 0000
    0004460​

    For all the images I tested.

    Any of you remember / know how to uncompress these?

    Well, they are obviously compressed... so you'll literally have to uncompress them.

    They're compressed with PocketISO.
    PocketISO can also decompress them.

    Extracting the pocketiso .z file yields an iso (.bin) but no .cue and pcsx won't load.
