Super Mario Advance 4: Super Mario Bros. 3

Super Mario Advance 4: Super Mario Bros. 3 is pretty much exactly like Super Mario Bros. 3, except that now there are now four bars in your closet to store items. Its great because its for the Game Boy Advance.

Another cool feature is that if you have an E-Reader, you can scan Super Mario Advance 4: Super Mario Bros. 3 e-cards to get new suits, items, levels, and switches that modify the engine etc.

e-Reader features
The Mario Advance 4-e cards were planned to come in 4 series, but 3 and 4 were canceled before ever being printed, due to the poor sales of 1 and 2. Cards could be scanned into an e-Reader that was linked up with Mario Advance 4 and download levels, power-ups, switches and demo movies. Levels could be played from a unique world and a certain number of them could be saved. There were trophies of Mario items that could be found in these worlds, as well as rare red coins that could be accumulated to unlock new content. However, due to the premature termination of the series, one could not unlock all the features even with every red coin from every available level. The power-up cards would put things like Tanooki Suits, Super Mushrooms and P-Wings in the player's inventory. Many levels contained unique gameplay devices; one even let Mario attack with a boomerang like Link! Switch cards could be swiped to alter the game engine (i.e. one puts radishes in regular stages). Demo cards contained movies that controlled Mario in certain levels. When swiped, they could be used to watch superplays or show how to access secret locations in the game.
