Re: PS3 Update 1.91 Request
I'm just a random user, but I think you should ask the romfinders on the "Request" Board.
Does anyone please have the 1.91 system update as required by
BLUS-30074 Guitar Hero III - Legends of Rock
It appears to be the only game that contains the 1.91 update and it's not listed here https://www.psdevwiki.com/ps3/System_Firmware as an available update.
