Changes

For a long time (before the availability of Cobra and Mamba) the only playable format for PS3 backups (relying on little more than "peek and poke" CFW-provided syscalls to mount the game's folder over the currently inserted disc) but also the least accurate one, with significant compatibility issues (varying on whether the backup is stored on an internal or external drive, whether an original game disc is currently inserted, various optional hacks such as "BDMirror" moving the files to the root of the external drive on demand, ...)

Currently [[Save_disk_space_for_ISOs#External_links|there is no ISO or any compressed file support for RPCS3]] but you can use [https://github.com/RPCS3/rpcs3/issues/4021#issuecomment-1650682400 this tool] for playing your ISO dumps with RPCS3.
