  • Compressed PS2 roms: anyone else have an issue with many games not working (boots, stalls when it actually has to load more than a menu or background), likely due to .CSO format? (the few .ISOs I have still work, including one where the .CSO doesn't)

    I can't seem to reverse them back into .ISOs w/o an error (though I've only tried the one thing that may have caused this in the first place) so I'm not sure if this is a corruption or software thing, is my best option here to re-rip (and use .CHD instead)? Linux, emu is v2.3.272

    • The fact you can't decompress the games suggests to me whatever program you used didn't operate correctly whether it's faulty programming or user error.

      You're already suspecting this, and I agree. These aren't lossy compression methods, so the file should decompress to original state, matching hashes, yada yada.

      I can't remember if my ps1 and 2 sets are CHD or CSO. I'll report back if I kept the specific tools I used. Usually do. I know the games work, been playing the compressed games for years now.

      I will say, speaking from experience, some of these solo dev github tools we use don't handle network drives correctly. Just in case you're using a NAS.

        I've looked through different (now closed) issue threads emulator-side and it might be an issue with some other (system) library change. Though yeah, tool I used seems to be old too (ciso, perhaps I should've found a newer tool but it is niche). I also can't verify .CSO roms via the gui, as it crashes PCSX2 too.

        For some info, Ratchet and Clank is one that blackscreens (when starting/loading game or even when letting it sit at the menu too long) a different one that seems to work fine is Ratchet Deadlocked (though I didn't go past the tutorial). Assuming Deadlocked is fine, it also doesn't decompress so (given that it coredumps too) it may just be broken in that tool even for a valid file.

        I also remember seeing this issue with The Sims 2 making me stop making new .CSO files, though I could've sworn my others (like RAC1) were still working at that time. Though maybe loading from save-states each time made me not see the initial loading issue.

        EDIT: Also sorry I just noticed the other pinned thread, I probably should've originally commented there

        • Alright so! I looked through my folders (I don't delete anything) and my memories came back to me. I had the exact same issue with ciso on Windows. Gave up, and used CHD instead. Both sets are in CHD, originally sourced as ISO from myrient (see sidebar of this community). The compression folder had both tools in it. I couldn't remember if I was conflating the memory of black screen on boot with RPCS3 before I figured out how to decrypt bluray ISO properly or not.

          So sorry can't help much, I can say CHD works at least.

          edit: oh and, it's okay the forum isn't busy enough for me to care yet.
