I have my original one still, I absolutely loved it. I could never afford a DSTWO when I was younger, but I did grab one of those DSTWO clones that appeared on AliExpress a year or so ago.
So far, I cannot seem to achieve this. If I run GW mode on my SysNAND, it wipes boot9strap. I do recommend having EmuNAND though for this purpose, meaning you don't have to screw up anything.
only ps5 updated to latest firmware can go on psn, jailbroken ones just don't use psn or they risk getting flagged or banned, altho spouting profanity in online play alredy does that
