Super Mario Advance 4. The Japanese edition you didn't know about

If you remember the "E-Reader". Super Mario Advance 4 implemented the usage of this device greatly, but what we didn't know was that the JPN edition had special cards that could turn the game into the Ultimate SMB game you have ever witness. Watch this video from the link to see what I'm talking about....picture using the Cape from Super Mario World in Super Mario Bros. 3....or able to lift things like Super Mario Bros. 2 in Super Mario 3.
