About Super Mario All-Stars

This cartridge contains the 4 Super Mario NES games.

- Super Mario Bros.
- Super Mario Bros. - The Lost Levels (aka Super Mario Bros. 2 Japan)
- Super Mario Bros. 2 (aka Super Mario Bros. USA)
- Super Mario Bros. 3

The graphics and sounds are much better than the original NES versions and you can save after the end of each world (except for "The Lost Levels" where you can save after each level because of its difficulty). The gameplay and level design has not changed for most of the games but Lost Levels has been made easier reach the A to D worlds (there are 13 worlds total).
