Here is a hack which combines: Mario Bros., Super Mario Bros., Super Mario Bros. 2 JPN (The Lost Levels), Super Mario Bros. 2 USA, and Super Mario Bros. 3. Also added into this hack is the ability to use SRAM to save your games and to save your top score in Mario Bros. This game is using Mapper 005 (MMC5) and it uses 1MB/1024kb’s of PRG-ROM, & 1MB/1024kb’s of CHR-ROM. Except for Super Mario Bros, all the other Mario games are converted to MMC5 as well. Note: An MMC5-capable emulator is required, otherwise the graphics will be a garbled mess. To access Mario Bros, on the game select screen, hold A and press Up on Super Mario Bros.
