CSO support?

Post by kruuth » August 31st, 2017, 5:25 am

Is there any plan to include CSO(Compressed ISO) support to PSIO? It's would make storing games a lot easier.

I didn't even know that was a format. The problem with compression is, they need an algorithm to decompress the data on the fly to stream what's needed or to either decompress them and store the raw data somewhere. We don't have that type of working room and it would probably slow down the load procedure in order for a few hundred megs of room.

CSO was a commonly used ISO image variant used in the PlayStation Portable scene. Nice for the most part on storing games but some titles, most notably Square-Enix titles, would suffer the most.

Oh, I thought that was the EBOOT format. Never heard of CSO.

EBOOT.PBP I believe was Sony's official "ISO" file that had the Sony specific key encrypted to PSN bought games. When you dumped a UMD via the various homebrew methods, you'd get the ISO format which then could be further compressed to CSO via a program called UMDgen. Pretty cool shit really. I love those HEN's (Homebrew ENablers) the PSP scene had. I was able to put all my UMD games on my PSPgo :D
