Yep. The PS4 and Xbone are both very close to off-the-shelf AMD APU’s as far as I remember; you could buy very similar processors for desktop use. Emulation would require a ton more power than the original chips, and the original chips are so close to desktop processors that it’s more efficient and feasible to reverse-engineer the proprietary API’s those console chips use.
No public sources yet, but there are positive whispers from anonymous people in the electronics supply industry. Companies that make boards, chips, screens, that kinda stuff. That plus the fact that the original Switch launched in 2017 is enough for me to believe the new one is on the way.
Oh jeez, did some brief research and that is awful. The person in charge of Retroarch seems to be a greedy asshole, doesn’t properly credit other people’s code, and there’s direct IRC-logged evidence of abusive behavior towards emulator devs. Yikes. No wonder there are competing projects.
Time for me to never touch it again. I hear LaunchBox is a fine alternative but on my Switch I might just grab ARM builds of individual emulators; it would save time over the whole RA interface anyways.
