The original Switch almost certainly can handle GameCube games.
VGChartz's Evan Norris: "In the end, Mario Kart World doesn't surpass its predecessor, Mario Kart 8 Deluxe. But that's like failing to surpass Resident Evil 4 or Half-Life 2; there's absolutely no shame in it. Judged on its own mechanics, systems, and merits, it's a brilliant racing game, a GotY contender, and one of the finest entries in the entire Mario Kart canon, not to mention another in a long line of exceptional launch titles from Nintendo. Is there room for improvement? Yes. The open world could be more organized, the 24-player Grand Prix races could be less chaotic, and the online customization options could be more flexible, but these are relatively minor issues in such a polished, daring, substantial, and joyful game that promises to provide reliable entertainment for years to come."
Rune Factory: Guardians of Azuma is not just one of the best offerings from the series, but in the genre as a whole.
In this case, it's quantity over quality.
Yeah I doubt there's a technical reasons why it's locked out of the origin switch I had GameCube emulation running fine on the Wii U
The Switch is an extremely capable console when it comes to playing GameCube games. The reality is that it's a paywall to push their newer hardware, which is lame.

If you support Nintendo’s behavior, this is what you’ll get. They’ve been problematic for a long time, but damn if they don’t make some great games. It’s hard as hell not to give in. I’m definitely gonna hold out this time. Sucks though, because I want to play that GameCube Fire Emblem game.
