I haven’t kept up, since the exclusives I wanted to play worked on the low firmware and new ones stopped coming out and later ones like Ghost of Tsushima ended up coming to PC.

Last I remember is higher ones than mine requiring a usb stick.

I guess higher firmware requiring bluray now isn’t any more strange than the RCM jig method on older Nintendo Switches. Now that was an excellent solid jailbreak experience being able to install custom firmware.
