I mean, for what it is, it's a good frontend and many emulators run quite fast on Wii U, but for whatever reason, it's unstable. Maybe it's the Wii U itself, maybe there are RAM leaks, I don't know. I'm not ungrateful for the work that has been put into RA after all these years, don't get me wrong. It's just a damn shame that it's seemed to have died an ignominious death, and it's why I'm very cynical of the Switch homebrew scene. All the devs jumped ship and went over to there instead.
I've been avoiding the Switch homebrew scene intentionally, because of what it cost what little there was left of the Wii U scene. Pure bullshit.
