A special version of this title was packed in with some Super Nintedo's, the game featured all of the original Mario games featured on the original cart as well as "Super Mario World." Also the game featured a red title screen as opposed to the normal blue one.
This compilation features the release of the original Japanese version of "Super Mario Bros. 2" ("Super Mario Bros. - Lost Levels") for the first time in America.
The Super Mario 2 game wasn't intended to be a Mario game at all. It originates from the Japanese game "Doki Doki Panic", which was reworked by Nintendo (they changed some sprites and screens) and released in USA as "Super Mario Bros. 2". In Japan, there is another SMB2 - which is called "Super Mario Bros. - Lost Levels" in this cartridge, which is a REALLY hard version of SMB1.
