Despite having a powerful editor and being a game that's easy to edit, NSMB2 doesn't have very many hacks in the making.
New Super Mario Redux is a ROM hack of New Super Mario Bros. 2 that aims to replaces all of the levels (eventually including the DLC packs). Particular emphasis is put on the quality of the levels; I work slowly and I test each level numerous times to make sure they're fun to play and free of technical problems.
