I have my ps4 on version 5.05 with al-azif cached on it. When I put in my game disc (Retail disc of Rainbow Skies) it says "Playstation 4 Format Disc" and tells me to update to 5.50. I would rather not update.
Is there any way to play the retail disk without updating? Is there a spoofer pkg or...
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
