It's very interesting but I can't seem to find anymore tech details other than you need an older firmware, because you need to run a full chain exploit (https://www.notebookcheck.net/A-modder-has-successfully-port...)

Also, can you do this and still be able to access the original OS? It be nice to run Linux on it, but I'd also need to access my PS5 library, so do I need two machines for this?
