Maybe Valve needs to stop pushing updates for things they certified working until they certify the update won’t break them.
Never understood why Steam forces updates, but this would be a very good reason for them to do a 180 on it and let customers choose the version they want instead of forcing an update to the latest.
It doesn’t need anyone to convince devs to implement it. I can do it whenever I run an emulator of old console games already, and devs of those games never implemented it.
If Sony wants to add it as a hardware feature they can.
As far as the patent, hopefully it’ll get denied but I doubt it. Once they have it it’ll cost someone time and money to challenge it, even though it should be a slam dunk that it is neither a new idea nor innovative and novel. This is how a lot of these egregious parents continue to stand - the cost of challenging them is high, especially if some blistering idiot of a judge ruled in a farcical manner.
