Can we add a category for the kiosk demo? It's gotten some attention, e.g. here: I'd also be up to running it.

For info on what the demo actually is, see here: https://tcrf.net/Mario_%26_Luigi:_Superstar_Saga/Kiosk_Demo

No. Simply put, there's no point in adding an extraneous category for a portion of the game that's already present in every category already. There's nothing wrong with doing runs yourself for fun, but we attempt to keep the leaderboards as simple and concise as possible.
