I’d say they must mean PC - It runs fine for me with Yuzu on a good gaming PC using OpenGLSL. It’s locked to 30fps though unless there’s some setting I don’t know about.
It’s so far unplayable for me on the SteamDeck because of the requirement for OpenGLSL - it works, but it runs at about 10fps. Using Vulkan seems to be closer to 30fps on SteamDeck, so I imagine when this is fixed it will be playable on the SD, but that is not the case right now. I’m using the latest pinEApple build.
