Super Mario Land
Developer: Nintendo R&D1 Publisher: Nintendo Platform: Game Boy Released in JP: April 21, 1989 Released in US: July 31, 1989 Released in EU: September 28, 1990 This game has unused music. This game has revisional differences.

Super Mario Land is the first portable game in the Mario series, as well as that time Mario cheated on Princess Peach with Daisy.

Unused Music

To listen to all of the game's sound effects and tracks, you can edit memory addresses $DFE0 and $DFE8, respectively.

Ladder-Climbing Theme

The ladder-climbing track is much longer than it needs to be, running about 7.7 seconds even though only the first 2.2 are heard in normal play.

To listen to the track, you can edit address $DFE8 to 0x0A or alternatively, you can use a Game Genie code that plays the track in World 1-1 depending on which version you have:

Version	Code
Rev 0	0A7-B7F-F76
Rev 1	0A7-CEF-F76

Unused Hidden Block

The game reserved a tile in these two places in World 3-3 for a hidden block. But it cannot be triggered and therefore is unused.

Revisional Differences

The game received one revision, which included polished music and a bug fix. However, the 3DS Virtual Console version is the original Rev 0 version, which is odd because nearly every other Virtual Console game uses the latest released revision in each region.

Audio

All of the music was changed stereoscopically from version Rev 0 to Rev 1.

The death jingle and goal fanfare had a noise percussion track added in version Rev 1:

Death

Rev 0
Rev 1

Goal

Rev 0
Rev 1

Almost unnoticeable, in some tracks the first percussion sound was moved from stereo to right channel:

Sarasaland

Rev 0
Rev 1

Cave

Rev 0
Rev 1

Rev 1

For the autoscroller theme, the percussion was changed from alternating between both channels to always stereo:

Rev 0
Rev 1

Popping was removed from some tracks, which is particularly noticeable in the intro of the Chai Kingdom theme and the track that plays when you rescue Daisy at the end of the game:

Chai Kingdom

Rev 0
Rev 1

Oh Daisy

Rev 0
Rev 1

Audio IDs

There is a difference in how audio tracks are handled. Version Rev 0 will accept invalid audio IDs and attempt to play (glitched) soundtracks. Version Rev 1 doesn't play invalid IDs at all.

Screen Wraparound Glitch

There is a glitch that allows Mario to wrap around the screen on autoscrolling levels by holding Left while he is getting pushed offscreen. This was fixed in version Rev 1.

Misplaced Objects

There are misplaced enemies and platforms in some levels which suggests that the level layout was changed and due to the developers' oversight, the objects were not adjusted to match.

Falling Enemy

A Nokobon/Bombshell Koopa that is placed right above a pit in World 3-2. If you're quick enough, you can just barely see it as it falls to its doom.

Platforms

Falling platforms inside the ground.
