Super MarioMon is a GBA ROM Hack by Kobazco based on Pokemon Emerald in English. It was last updated on April 14, 2026, and is now available to download.

Description

Super MarioMon is a wild and creative fusion of the Super Mario universe and classic Pokémon gameplay. Play with iconic characters like Mario, Luigi, Bowser, and more—reimagined as catchable Mariomon. Explore quirky, remixed regions, take on chaotic battles, and chase the dream of becoming a Mariomon Master. It’s Mario meets Pokémon with a heavy dose of unpredictability and fun.

It is important to remember that Super MarioMon is a fan-made passion project, lovingly crafted by a dedicated team of creators. Thanks to Alpharad’s sponsorship, Kobazo and the crew were able to take their wild vision and make it real.

Gameplay

“Super MarioMon” throws platforming out the window and replaces it with chaotic turn-based strategy. Mario characters become battlers, each with distinct stats, types, and abilities. Traverse nostalgic Mario worlds—but instead of stomping enemies, you’ll be crafting battle plans, exploiting type matchups, and juggling crazy item combos.

The game blends Mario’s charm with Pokémon’s strategic combat, and the result is gloriously unpredictable. As seen in Alpharad’s streams, anything can happen—random events, wild item effects, and sheer dumb luck all play a part. It’s tactical madness with a Mushroom Kingdom twist.
