STORY:
While Mario was away fighting Bowser’s cool uncle and saving Daisy (in the events portrayed in Super Mario: The Daisyquest), Princess Peach was kidnapped by Bowser. Peach waited and waited for Mario to show up, but to no avail. She waited until the day her wedding with Bowser was scheduled for… but then she decided to take matters into her own hands, thus becoming the titular Runaway Bride!

Now she has to fight her way through the Bowser-occupied lands of Eastern Mushroom Kingdom with Bowser on her tail…

HACK INFO:
Changes to the original game include but aren’t limited to:

- 5+1 worlds for a total of 21 unique levels:
World 0 is only one level long - it represents the initial wedding scene.
Other worlds have 4 levels, arranged as follows:
- w-0 - “Castle Run” - escaping the wedding through a fortress on a short time limit
- w-1 - Normal level
- w-2 - Normal level
- w-3 - Normal level, ending with a “wedding trap” (a Bowser fight)
Targeted difficulty of the levels was somewhere between SMB1 and Lost Levels, and the hack gets harder as you progress through it. But, the starting number of lives was increased to 15 and there is at least one hidden 1-up in every level, so the difficulty is eased that way
- Custom powerups and powerup system
The ROYAL CROWN - gives the Princess an extra hit, ability to bust blocks, and ability to tame the power of the Power Bolt
The POWER BOLT - does different things depending on the current powerup state
The MAGIC LAMP - gives or takes away the ability of flight
The 1-UP
- Custom/customized enemies - Phanto, Bat, Bird, Bullet Parakoopa etc.
- Custom blocks
“R” block - gives a checkpoint. Has to be re-hit when respawned, otherwise the checkpoint goes away.
Spikes - downward facing spikes hurt you when hit on head, but can be walked on. Used mainly in levels with flying sections.
- Partially custom soundtrack
- Revamped scoring system
- Many tweaks and adjustments to make the game feel more polished
