The true final installment to this series? You can say that, but not without the E1S touch. Something very unique is done for this truly last installment to the NEW series. This hack is complete with new graphics, some from the games, and some are original. Test your way through another set of new levels, repeated stages, default SMB3 level with slight modifications, and the map screens resemble the 1 path aspect of the modern Mario games. Enjoy folks!
Update: December 13, 2014, this new patch corrects the end castle of World 6.
