penny-arcade forum has the scoop from Nintendo Power’s latest issue. It looks pretty clear that this is going to have some of the greatest elements of the original SMB as well as a few things incorporated from SMW and SM64.
MAY 7 CANNOT COME FAST ENOUGH.

Well it’s getting real close now to the year’s most anticipated game*! Super Princess Peach, the Super Mario Bros. style side scroller for the Nintendo DS, is hitting stores in a little over 2 weeks now on Febrary 27th.

Check out the official site which has pretty much no information and a weird little flash magazine maker program.

* According to aDam

After being announced nearly a year ago very little has been heard of about this game. Check out IGN’s page for some old screenshots and a video. This 2D side scroller for the Nintendo DS is a classic Super Mario Bros. style game featuring Princess Peach Toadstool as the hero.

Finally in the October 2005 issue of Nintendo Power we get some news about this game. It will feature over 40 levels. The dual screen will be keep constant track of Peach’s mood which is affected by power ups transitioning it over 4 different emotions. No word on how these emotions will actually affect game play.

A look at a screenshot included in the magazine shows that there has been a graphics overhaul since the first images seen last year. Most notable are the improved graphics on the emotion window, which is now on the bottom instead of the top, and the main window can be seen to have differences in the health metre, points and stuff.

The game is slated for an October 20th release date in Japan. No date has been set for a domestic release yet.

N-Philes has a great feature about game Hacks that have been found for SSBM. The most interesting is you can play with any character(The Hand and Sandbag) in the game. Over 60 boards to fight on and 6 player action. Of course you can only use 4 controllers but you can do 4 humans vs. 2 computers.

The codes(they require action replay) can be found here for version 1.0 of the game they also have 1.1 and 1.2 available.

They also have an interesting feature on Animal Crossing.
