I have no expertise in this field and this is what I got just from reading the article without doing any further research.
It seems that a consortium of giant tech companies got together to make a royalty-free video codec called AV1. This included getting legal agreements from a bunch of relevant patent holders that they wouldn’t pursue legal action against anyone implementing AV1.
However, due to the U.S. patent office’s current policy of issuing patents left and right and letting applicants sort out whether or not their patents are actually unique in court later, lawyers representing Dolby and a couple of other companies that hold some separate video-related patents have smelled money in the water and are trying to sort out whether or not their patents are unique in court.

Years ago I used to have Lakka on a bootable USB drive to turn an old, low-powered laptop into a dedicated emulation machine.
The specs are hard to read, but I believe the main processor is an AMD A6-1450 APU, designed for tablets and released some time in or after 2013. Not a powerful chip by modern standards, but IMO still useable depending on your expectations. It’s definitely capable of emulating SNES without breaking a sweat. Even PS1 shouldn’t be a problem at native resolution. N64, Saturn, and Dreamcast are probably where you’ll start seeing slowdown in some games, and anything more, like PS2 or GCN, is unlikely to be playable.
