@noctis90210 ebootlegger’s post followed Zecos tweet about 6.02 “method”, perhaps he’s part of the secret group who figured it out, who knows.
Until it’s released, we can’t know more other than snippets being picked up describing it as a “game share” quirk. I think I also gleamed that it is requiring a PSN title (possibly just a paid for donor rather than requiring a specific title like the old PSP methods). Again not 100% sure there.
This method will not have homebrew, will not have hen, and so any “5.05 game collection” will not work.
M0rpheus entrypoint (I think) will work on all firmwares (until patched ofc) but will require a kernel exploit on the fw you use it on to be a complete usable chain (so 4.05/4.55/4.74/5.0X will be useful). It sounds like webMAF userland (similar to WebKit entry) with code exec, but not kernel.
