  • 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
