This is probably going to come up at some point, Night's Miracle Sonic mod isn't a Category because even in New Game+ the only time you get 50 rings is at the end of QQ2, and transforming will lose you time. Even if we go over to All Good Futures, the only other time we get 50 rings is in QQ1 Past.

So while it's a great add-on mod that players would certainly be otherwise interested in, it's not a category here because there's no speedrun difference compared to the main game.
