It's not specified but is the 3D All Stars version of the game on Switch valid for Emu submissions? Specifically wondering about 70 and 120 star. I assumed it had its own leaderboard but the only categories on that page require running all 3 games in a row.

3D All Stars runs are in the category extensions

Ah I see, thank you! I would have never thought to look there for it, that's very strange.
