Does anyone know of a really great rom hack for captain toad tracker that adds more levels to it? Just beat the original game and wanted to see if there's any good rom hacks I can play while I wait for the sequel.
I don't believe any exist. There does exist an expansion DLC for the Switch version, that adds new levels, if you own one of those. The Wii U version has a handful of exclusive levels as well, they were replaced by the Odyssey ones for the newer releases. But I don't think anything like what you're looking for exists on the 3DS.
