Despite having a powerful editor and being a game that's easy to edit, NSMB2 doesn't have very many hacks in the making.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.A demo is almost done, and is slated to be released sometime before the end of June. It will feature a completely redone world 1, with all levels replaced and tilesets that are ports from NSMBU. In the future, depending on the state of custom music, I may include some new music (preferably custom pieces if I can get my hands on some).------------------------------------------------------------Special thanks to SuperML for making an old version of the logo.
