Bowser’s cool uncle has kidnapped Daisy, and it is up to Mario to save her. After fighting his way through 4 worlds, he finds him chilling in his pool.

This is a hack of the PAL version of Super Mario Bros., regardless which patch you use, so make sure your emulator is set to PAL. It works fine in most emulators except Nestopia, and was extensively tested in FCEUX and Mesen. Graphical glitches occur in Nestopia, so it is not recommended to use it for this hack.

The hack has 4 worlds of 4 levels plus one secret level, so 17 levels total.

Changes in REV1 (15/02/2023):

• one Koopa in 1-2 was red but walked off ledges, fixed
• some pipes at the end of 4-2 which shouldn’t have been enterable now aren’t
• a platform in 4-1 was cut off, fixed (aesthetical only)
• accessing the secret area was tweaked

Changes in REV2 (11/05/2023):

• a bonus area which was omitted from the original release due to glitches has been fixed and reimplemented
• jumpspring despawn glitch in 2-1 fixed
• decreased chance of jumpspring despawning in 2-4
• slightly altered title screen

Original version released 29/10/2022.

Have fun with this hack and thank you for playing!
