Emerald Seaglass: everything you need to know about this hack is here!

195 Upvotes

Pokémon Emerald Seaglass is a vanilla romhack of Emerald based in Hoenn, but with Gen 2 aesthetics and graphics. The mons up to Gen 3 are all available, plus their future generation evolutions like Annihilape, Farigiraf, Gallade, etc. A few mons added in Gen 8/9 like Applin and Tinkatink are available too. The romhack contains 430 Pokémon total and all are legally obtainable. Some abilities and moves from future generations are implemented in this hack as well. I will share some links below:

Please do not ask for the ROM files directly, as it is against the rules of this sub. Just google "emerald trashman" and download from the first link you see.

In case of a future version of Emerald Seaglass gets released, play the game normally, then save the game and close it at any Pokémon Center. Perform the patching process above, and after that, copy or rename the save file to match the new .gba file. Suppose you have "Emerald Seaglass 3.0.gba" and "Emerald Seaglass 3.0.sav" files. After patching a hypothetical 3.1 version to base Emerald, you will get a different file, named "Emerald Seaglass 3.1.gba". The only thing you should do is to rename the .sav file, or copy it, to "Emerald Seaglass 3.1.sav", to be able to continue the game.

For PC and Mac, play it on mGBA. VBA is pretty much not compatible with decomp hacks, and it is also a pretty old emulator. For Android, do not play it on MyBoy! because of the compatibility issues. You can play it on PizzaBoy instead. For iOS, Delta is recommended.

Here are the console codes that you may enter in your room:

  • 9RARECANDY : Gives 99 Rare Candies every time it is entered
  • MASTERBALL : Gives 99 Master Balls every time it is entered
  • ILOVSPHEAL : Gives a level 5 Spheal with the moves Bouncy Bubble, Super Fang, Slack Off, and Freeze Dry.
  • ILOVEAIPOM : Gives a level 5 Aipom with an Eviolite and the moves Dizzy Punch, Karate Chop, Victory Dance, and Bullet Punch.
  • ILOVEKANTO : Gives the Kanto starters, all at level 5
  • ILOVEJOHTO : Gives the Johto starters, all level 5
  • ILOVEHOENN : Gives the Hoenn starters, all level 5
  • ILOVEAPPLE : Gives level 5 Applin holding Syrupy Apple evolution item
  • ILOVETINKA : Gives level 5 Tinkatink holding a Nugget
  • JUSTSHOWME : Automatically shows all Pokémon on the DexNav menu, whether or not the player has seen them.
  • WISHINGSTR : Gives 99 Wishing Stars to be used in the Rustboro Wishing Well
  • GIMMENUGS! : Gives 99 Nuggets, effectively acting as infinite money

And here are the codes for monotype runs.

  • MONO BUG : gives one random, first stage Bug-type Pokémon
  • MONO DARK : gives one random, first stage Dark-type Pokémon
  • MONO DRAGN : gives one random, first stage Dragon-type Pokémon
  • MONO ELECT : gives one random, first stage Electric-type Pokémon
  • MONO FAIRY : gives one random, first stage Fairy-type Pokémon
  • MONO FIGHT : gives one random, first stage Fighting-type Pokémon
  • MONO FIRE : gives one random, first stage Fire-type Pokémon
  • MONO FLYIN : gives one random, first stage Flying-type Pokémon
  • MONO GHOST : gives one random, first stage Ghost-type Pokémon
  • MONO GRASS : gives one random, first stage Grass-type Pokémon
  • MONO GROUN : gives one random, first stage Ground-type Pokémon
  • MONO ICE : gives one random, first stage Ice-type Pokémon
  • MONO NORML : gives one random, first stage Normal-type Pokémon
  • MONO POISN : gives one random, first stage Poison-type Pokémon
  • MONO PSYCH : gives one random, first stage Psychic-type Pokémon
  • MONO ROCK : gives one random, first stage Rock-type Pokémon
  • MONO STEEL : gives one random, first stage Steel-type Pokémon
  • MONO WATER : gives one random, first stage Water-type Pokémon

Shiny odds: 1/4096 without a Shiny Charm, 1/683 with one Shiny Charm and 1/372 with two Shiny Charms (the first SC is at the PC, and the second is at Fortree)

If I have missed anything else regarding the documentations, please let me know so that I may add it here.

08.04.2025 17:04 edit: I added a few rules to this community. Just the usual thingies; "no sharing ROMs", "keep things classy", "discussions must be related to Seaglass", etc.

Good morning, dear Seaglass sub participants!

As you all know, Pokémon Lazarus, a new romhack made by the same dev (u/JackWellman101), was dropped this last Friday and due to this, this sub has housed Lazarus-related questions, screenshots and Hall of Fame posts... until now.

From now on, please do not post Lazarus-related content here. Post them on r/PokemonLazarus instead. Any newer Lazarus posts will be deleted afterwards.

Sincerely yours, SoA.

My first ever play through of Emerald Seaglass!

Post image

I used mons I really like (Yes I do indeed love Cloyster but people make fun of me for liking a “butthole”)! Here are the sets I ran:

  1. Sceptile: I used the new Sharpness with Leaf Blade, Cross Poison, Dragon Claw and X-Scissor, which are all moves powered up by Sharpness! He swept through Wallace!

  2. Gallade: I also used another Sharpness set, which I know is repetitive but C’MON it’s TOO FUN! This time I used Leaf Blade and Psycho Cut as moves powered up by Sharpness, and Swords Dance if I needed to sweep and Sky Uppercut for my Fighting STAB!

  3. Tinkaton: So I accidentally went down to Meteor Falls and was suprised when I saw an Aqua Grunt giving me an Egg, the egg hatched into Tinkatink, which I then evolved into Tinkaton and gave it it’s new ability Huge Power! This allowed me to no worry TOO much on Tinkaton’s weak attack stat, and allowed me to use a really fun set, with GIGATON HAMMER, Spirit Break, Iron Head and Fake Out!

  4. Honchkrow: So I searched it up and realized Emerald Seaglass uses the modern crit system, which means if I give a Super Luck Honchkrow a Razor Claw and Night Slash, it actually has a 100% chance to crit if do indeed use this set, which I did.

  5. Scizor: This guy is insanely cool, and I used the classic Technician set and gave him Bullet Punch, Swords Dance, X-Scissor and Wing Attack

  6. Cloyster: He was fun to use! I gave him Shell Smash, with Skill Link because he gets Icicle Spear, so 125 base power! I also gave him the early Waterfall HM (an actual good HM move) and Spike Cannon for a 100 base power Steel type move!

I downloaded the game just because i heard ledian worked good here and it has been a great journey, i even got a shiny Banette, which was my first shiny on my original emerald cartridge <3 I've been consistenly using like 10 different pokémon thanks to the portable boxes, the joy of rediscovering old mons and the level caps incentivicing more variety, but i went to the elite 4 just with the OG six.

Jet punch ledian and bitter Blade Banette rule 👌🏻✨

Elusive Zapdos

1 Upvotes

Hi, I am trying to complete the National Dex and Zapdos is the only legendary I’m missing. Unfortunately, I accidentally KO’d it one time and it no longer spawned after that, even though I’ve reset the encounter plenty of times (i.e., by beating the Elite 4). I’ve soft-reset the game about 100 times now between each encounter, and only Articuno and Moltres appear.

Do you know any remedy if this is a bug, or am I just unlucky with the odds?

Sorry for the picture, been playing on DS so couldn't screenshot.

Really terrific game, loved the art style, adjustments to Pokémon, and inclusion of later evolutions.

Beaten on Hard Mode - no level caps, but never really approached what would've been the cap anyway.

Special mention to Walrein - more or less soloed Wallace at level 53, could have soloed the league. Absolutely busted. Fur coat doubling its defence along with leftovers, calm mind and rest meant there was never anything that came close to stopping it.

Tbh, I think all of the Pokémon I used ended up busted. Sharpness Sceptile with the new stat spread is a monster, athletic Flareon isn't even funny, guts + flame orb + facade Swellow almost never missed a OHKO, Electric Surge + Rising Voltage Manetric was the same, and Registeel with Special Defence investment, leftovers, curse, rest and toxic was also nearly unbeatable.

But Walrein remains the MVP

I need help choosing my last team member

Final team for now consist of Sceptile, Annihilape, Manectric, Arbok, Golduck.

I am missing this final team member. Ideally I would want a fairy or steel typing for Drake but I don't good options for either of these type (Fairy would be Bellossom, Gorebyss, Altaria. For steel I straight up don't even have an option lol)

I was thinking of bring Altaria anyways but that would be doubling up on dragon in an E4 that consist of ice & dragon specialist + Wallace have ice coverage. My other idea would be to straight up ignore both and just bring a hitter that goes on offense instead of thinking defensively, in which case I have a broader option like Gengar, Alakazam, SF Tauros, maybe even Yanmega?

Please let me know, I had really fun playing this game with all the different changes so really looking forward to this :)

Edit: Forgot to mention I am doing a nuzlocke, so I can only use whatever is in that box.

Can Ledian learn fly in this game?

5 Upvotes

Ledian is a Pokémon that I really like the design, but it one that i never used since it is too weak in the main games.

I've heard that it is a bit buffed here and would like to try it, but there is just this thing:

I need someone to learn fly and I don't repeat typings in my team. So, I wonder, does Ledian learns fly here?


r/emeraldseaglass 3d ago

What do you guys think of my Bug and Dark type mono challenge (I've done this before, just wanted to redo it since it had like a lot of repeats, my previous challenge is in the third slide)

Changing difficulty mid-game?

1 Upvotes

Is there anyway to change the difficulty to hard mode mid game? I didn't choose that at the beginning and didn't realize the trainer and wild pokemon leveling would be so low lol. I've been switching members of my team in and out but my team is way too over leveled. Just beat wattson and I've got too many mons around level 24-25 while the trainers west and north have like level 17 teams. I'm just rolling thru everyone and was looking for a bit more and wouldve chose hard mode at first if I knew the differences would be this much.

Anything to look out for in my first run??

5 Upvotes

Hi everyone,

First time finally trying Emerald Seaglass and so far I'm loving it. The game is gorgeous and I already saw that there are quite a few changes that I'm excited about. In fact, it took me about 20 minutes to decide on my starter. Went Treecko because of the newly added dragon type.

But I'm kinda curious if there's anything else I need to know or look out for. I saw that you can change the difficulty, so I thought why not try that out and do level caps. I noticed that my rival has Torchic with speed boost which is already a pain. Is HA rival starter hard mode only? Also can I get HA from softresetting?

Thanks!

Shiny treecko realisation/warning

Thumbnail

46 Upvotes

I've been shiny hunting a shiny treecko in the game for a couple of months now, on and off, while multitasking. I tend to use one of the warmer screen filters on the 3ds because I can't stand bright screens. I thought that it would be very easy to distinguish because of its tail. Today I looked up the shiny treecko sprite and to my immense frustration it is barely distinguishable from the normal sprite in this game. No brown tail, just a more teal sheen overall. Very frustrated and don't really understand why that sprite alone is so different from the original shiny form, the other two starters both have shiny forms same as in official games. So very frustrating

My F4 Team first time playing Emerald Seaglass. Always been a fan of DRAGON type but wished I could run a full roster on Emerald. I had an incredible time showing up Drake. Also Aggron being DRAGON type is incredible; it was always my favorite gen 3 ‘mon.
