If you’ve spent any time in the GBA ROM hack scene, you’ve probably already heard people talking about Super Mariomon. It’s a Pokémon Emerald hack that swaps the entire Hoenn cast for Mario characters Goombas, Koopas, Piranha Plants, the works turned into catchable, battle-ready “Mariomon.” The version most people are searching for right now is the Alpharad’s Version, a community favorite build that’s been passed around Discord servers and ROM hack forums for its solid balancing and clean QoL fixes.
This page is your one stop spot to grab the ROM, the patch file and the older builds, plus a no-nonsense guide on how to actually get it running. No fluff, no five-paragraph backstory before the download button just what you need.
⚠️Quick heads-up before you download: Super Mariomon is a fan made ROM hack built on top of Pokémon Emerald. You'll need a legally dumped copy of the original Pokémon Emerald ROM that you own to apply the patch. We don't host or distribute copyrighted Nintendo/Game Freak ROMs only the .bps patch file, which is fan made content. Patching and playing ROM hacks exists in a legal gray area depending on where you live, so use your own judgment here.
What Makes the Alpharad’s Version So Popular?
A few things keep this build at the top of people’s download lists:
- Balanced difficulty – trainer battles actually feel like a challenge without being unfair.
- Smooth performance – runs clean on basically any GBA emulator, even on older Android phones.
- Active patch support – bugs reported by the community tend to get fixed in later versions instead of being ignored.
- Full Mario roster – it’s not just Goombas and Koopas, there are some genuinely creative fakemon designs pulled from deeper Mario lore.
If you’ve played other Pokémon Mario crossover hacks before, this one tends to come up as one of the more “finished feeling” builds rather than a rushed beta.

That’s it if you’re grabbing the pre patched full ROM. If you’d rather patch it yourself, keep reading.
Patch Files What’s the Difference?
You’ll usually see two download options on hack sites like this: a full ROM and a patch file (.bps). Here’s the actual difference, in plain terms:
- Full ROM Already has the hack applied. Download it, open it, play. Easiest option.
- Patch File (.bps) A small file containing only the changes made to the original game. You apply it yourself onto a clean Pokémon Emerald ROM using a patching tool.
Why would you bother with the patch route when the full ROM is right there? A couple of reasons people prefer it:
- It’s the more “legit” way to do ROM hacking, since you’re applying a fan patch to your own legally owned base ROM instead of downloading a pre modified copy.
- Patch files are tiny (a few MB) compared to full ROMs, so they’re faster to grab and easier to Redownload if something goes wrong.

How to Patch and Play Super Mariomon
This part trips up a lot of first timers so here’s the breakdown step by step.
Step 1: Get the Required Files
You’ll need three things before you start:
- Pokémon Emerald (USA) ROM – your clean, unmodified base ROM
- Super Mariomon .bps Patch – the patch file from this page
- A patching tool:
- Windows/Mac/Linux: Lunar IPS or Floating IPS (Flips)
- Android: UniPatcher (free on the Play Store)
Step 2: Patch the ROM
On Windows/Mac/Linux (using Lunar IPS or Flips):
- Download and open Lunar IPS or Flips.
- Click Apply Patch.
- Select SuperMariomon.bps as the patch file.
- Select your Pokémon Emerald (USA).gba as the base ROM.
- Save the output with a new file name (e.g., SuperMariomonPatched.gba) don’t overwrite your clean ROM, in case you need it later.
On Android (using UniPatcher):
- Install UniPatcher from the Play Store.
- Open the app and select your .bps patch file.
- Choose your Pokémon Emerald (USA).gba as the base ROM.
- Tap Apply Patch and save the new file.
Step 3: Play the Game
- Open your GBA emulator of choice.
- Load the patched ROM file.
- Start a new game and you’re in.
If the patch fails or the emulator shows a checksum/CRC error, double check you’re using the correct region Pokémon Emerald ROM (USA), not the European or Japanese release this is the #1 reason patches fail.
Best GBA Emulators to Run Super Mariomon
Any solid GBA emulator will run this hack fine since it’s not pushing any crazy hardware limits. These are the ones the community generally recommends:
On PC (Windows/Mac/Linux):
- mGBA fast, accurate, actively maintained and our top pick
- VBA-M older but still reliable, lots of save state options
On Android:
- My Boy! smooth performance, great save state support, small price tag
- John GBA Lite solid free alternative
On iOS:
- Delta the go to sideloaded emulator for iPhone right now
- Provenance another solid option if Delta isn’t working for you
mGBA tends to be the safest pick across the board if you want one emulator that “just works” without fiddling with settings.
Features That Make Super Mariomon Worth Playing
- Full Mario-to-Mon conversion – every catchable creature is reskinned and reworked around a Mario Bros. theme, not just a sprite swap.
- Custom maps – routes and towns are redesigned to fit the Mushroom Kingdom vibe instead of reusing Hoenn’s exact layout.
- New rival and trainer characters – familiar Mario faces show up as gym leaders, rivals, and trainers throughout the story.
- Reworked move pools and types – some Mariomon get unique movesets that play differently from their original Pokémon counterparts.
- Quality of life tweaks – faster text speed, improved item management, and other small fixes that make the grind less tedious than vanilla Emerald.
Gameplay Overview
If you’ve played Pokémon Emerald, you already know the gameplay loop here turn based battles, gym style progression, catching and training your team, exploring routes and towns. The twist is everything’s reskinned and rebalanced around the Mario universe. You’ll be tossing out a Goomba instead of a Zigzagoon, battling a Piranha Plant gym leader instead of Roxanne, and building a team around movesets that don’t always match what you’d expect from the original game. It scratches the same itch as classic Pokémon but with enough changes to keep it from feeling like a rerun.
Tips for Beginners
- Back up your clean ROM before patching. If anything goes wrong, you don’t want to redownload the base file from scratch.
- Use save states early on. GBA emulators let you save anywhere, anytime use it before tough trainer fights so you’re not replaying 20 minutes of dialogue.
- Check movesets before assuming they match the original Pokémon. Some Mariomon hit way harder or weaker than their Hoenn counterparts, so don’t go in blind.
- Turn on fast text/battle animations in the options menu if your emulator supports it it cuts down grinding time a lot.
- Keep the patch file even after you’ve played, in case you need to re-patch on a new device later.
FAQs
