Well, surprise everyone!
I've been working on this hack ever since finishing Clone Tag Team 2 with the intention of surprising everybody with it once New Year's Day rolls around. And well, in Australia the clock just rolled over to 12.
New Super Mario Advance is a full remake of Super Mario Bros. 2 on the NES, with new and remixed levels. It's all there in the trailer. This hack mixes in classic Mario elements to the otherwise "unusual" gameplay of the USA's Super Mario Bros. 2; aka Doki Doki Panic!
This hack is also a remake of something else- my godawful first NSMB hack which I somehow thought was good enough to even show to the public let alone release. Now it's completely rejuvenated and actually kinda playable.

This is an .xdelta patch and can be applied with an .xdelta patcher. Of course, you'll need a clean US ROM of New Super Mario Bros. for Nintendo DS. Please enjoy, and Happy New Year to all you tempers!
