About This ROM Hack
Super Mariomon is a full-scale crossover ROM hack that merges Pokémon gameplay with the Mario universe, featuring a completely original region: the Mushroom Kingdom.This is Too Many Productions’ most ambitious project to date, offering a fully custom region, original mechanics, extensive quality-of-life options, and a complete postgame, all wrapped in a lighthearted, fun-focused adventure.
Story Overview
Princess Peach is hosting a grand game for everyone in the Mushroom Kingdom!The rules are simple:
Whoever collects all 8 Power Stars scattered across the kingdom’s various worlds will be granted a wish.
However, Bowser is also competing—and he’s not playing fair.
Your journey is a mostly free-form adventure, focused less on high-stakes drama and more on exploration, humor, and creative encounters, as you race Bowser through the Mushroom Kingdom under the supervision of Professor E. Gadd.
