Alas, the live service, bane of the patient gamer.

I picked up the original Super Mario Maker on WiiU for cheap a few years ago but haven't really played it much (who knew that professional level designers are better at designing fun levels than internet randos?), but apparently its servers are being shut down on 8th April. (This has apparently been announced for a while but I only discovered it from recent articles about players trying to beat every level!)

Does anyone know if there's any way to mass-download levels before the servers go offline? Is it just a case of manually downloading all the top levels one by one? Should I just play it intensely for two weeks assuming it'll then be reduced to the default levels regardless? Are there third-party tools to download levels on Cemu instead?
