Known glitches

No game-breaking glitches so far. There are a few graphical glitches which can lead to certain awkwardness/hilarity.

  • When meeting Steven in Sootopolis, he takes you on a magic walk-though-walls trip before finally dropping you off in the Cave of Origin. Again, completely graphical and doesn’t harm the progression of the game. Certainly looks funny though.
  • Sometimes Cyberdramon will pop out of a rock after you Rock Smash it. It’s catch rate is 0, so don’t waste pokeballs trying to catch it.
  • Poyomon will evolve into all sorts of wacky things when given DigiEggs. PGE won’t let me edit this for whatever reason so there’s nothing I can do.
  • I haven’t edited the postgame AT ALL. So don’t bother checking out the Battle Frontier unless you feel like entering Glitch City lol

Installation Instructions

  • Step 1: Find a clean Rom of Pokemon Emerald off Google. Look for the “Trash Man” version.
  • Step 2: go to RomPatcher (https://www.marcrobledo.com/RomPatcher.js/)
  • Step 3: Upload the vanilla Pokemon Emerald and the Digimon Emerald Project patch file.
  • Step 4: Hit “Apply Patch.” The patched rom will download automatically.
  • Step 5: Enjoy!


  • Save often. If you use VBA like I do, then you’re probably used to abusing the speed-up button. Go easy on that. Using it too much will make the game freeze, especially during battles.
  • Don’t go “Shiny hunting” because there are no shinies in the game. Sorry.
  • No need to go fishing more than once. Only one Digimon can be caught via fishing: Manbomon.
  • Breeding is not possible because the Day Care only takes one Digimon at a time.
  • While all Digimon are viable, some have higher stats than others. They generally run on “short-term gain, low investment” vs. “high investment, high payoff” archetypes. If you come across a horribly weak baby Digimon, chances are it will grow up to be a total monster if you put in the time.
  • The game is about 1.5 times harder than vanilla Emerald. I’ve playtested the game four times now and was able to beat it pretty easily, but then again I made the damn thing so of course I’d know all the best strategies.
    My advice is to use stategy. Grinding is not the answer. If you lose against a Gym Leader once, don’t go off and grind for five hours. Try a few more times and see if you can figure out his movepool. Using brute force will not work in this game because all Gym Leaders have an “ace” with full coverage. Use strategy instead.
  • This game is a bit easier than Digimon Nova Red (my previous romhack), if you’ve played that.
  • You crazy nuzlockers should probably keep the dex open so at least you know what you’re up against.


  • 5/25/2022: Version 2.0 – Definitive complete version. Dex is now at 352. HM moves are now deletable. A few bug fixes.
  • 5/8/2022: Version 1.1 – Every Digimon now has a signature move. Also a few minor bugs fixes.
  • 4/9/2022: Version 1.0.3 – Day care no longer allows breeding, fixed some Typing issues for attacks and a few mons (“Cool type,” lol). some catch rates have been improved, some Mons have been given better Abilities, etc. Minor fixes like that.
  • 3/27/2022: Version 1.0.2 – Patched a few bugs, all signature moves have custom animations now, item pickups are actually useful
  • 3/18/2022: Version 1.0.1 – Waterfall now obtainable (next to Juan in gym)
  • 3/16/2022 : Version 1.0 initial release




Any Cheat codes?

Don’t know! Maybe try some out and get back to me?

Why only 350 Digimon? Other hacks have a much more complete dex.

Quality over quantity, my friend. The other Digimon hacks online don’t take the same approach to their spriting. When it comes to Champions and up, most other Digimon romhacks simply compress the sprite until its small enough to fit into the 64×64 box. Their backsprites also tend to follow a similar procedure of simply enlarging an overworld sprite.
I totally respect the approach of other Digimon romhacks. But this is not the direction I chose to take with Emerald Project. Digimon Emerald Project is supposed to provide a clean, consistent experience in which every Digimon looks good. And despite my best efforts, there’s still about three or four sprites I failed pretty hard at lol

Why am I still playing as Brendan and May? Shouldn’t I be Tai or Sora?

The Digimon world is fundamentally different from the Pokemon world. In Digimon canon, Tamers do not go around capturing Digimon and keeping them on their person for friendly competition.
Therefore it would make no sense for Tai to go around capturing hundreds of Digimon and storing them in his PC on a quest to become the “Digimon League Champion.” That sounds more like the behaviour of the Digimon Emperor than anything (haha).
It’s helpful to think of Digimon Emerald Project as taking place in an alternate universe identical to the Pokemon world in every way, except this world is inhabited by Digimon instead of Pokemon. No other narrative or structural changes.

Can you add in ____mon in a future update?

Sure! If you want to provide the sprite and it’s up to quality, then I would be happy to add in more Digimon at other users’ request. If no compact sprite is available, I can still work my magic if the particular Digimon is in “high demand.”
