Description
Pokémon Tourmaline is a loose sequel to Pokémon Emerald. This game is intended to take place in an alternate timeline where the setting and events diverge from the official games. Most notably, some mechanics from later gens are absent, others have been reworked, and several new mechanics have been introduced (see below for more information).
Story
It has been several years since the battle between Groudon and Kyogre wreaked havoc on the Hoenn region. As more information about Pokémon’s origins becomes available, humanity’s understanding of the game grows. A recent surge of discoveries in the nearby Issho region has attracted researchers from all over the world, including May, who is now an assistant Pokémon professor. After receiving a Pokémon from her, the player sets out to investigate reports of new Pokémon species and types from all over the Issho region, as well as other strange phenomena. Meanwhile, a new threat is emerging in Issho, a mysterious crime syndicate that employs extremely powerful Pokémon.

Known Issues
- Emulator Speedup: Can cause unpredictable glitches. Use sparingly and save often.
- Double Battle Glitch: After a double battle (e.g., Twins), wild battles may behave like double battles, sending out two Pokémon. Catching Pokémon works normally, and fighting a single trainer fixes the issue. This glitch does not occur after double battles against two separate trainers.
- Pokédex Glitch: New regional forms may show incorrect sprites, displaying the base form instead.
- Status Bar Glitch: Enemy status bars may display incorrect colors for status conditions. This is a minor graphical issue and often resolves itself.
- Cinerous Town Glitch: The gate at the top of the map may use the wrong tileset. Entering and exiting a building temporarily fixes it.
- Doors: Some doors change color when entered. Proper animations will be added in a future update.
- Windows at Night: Sometimes display incorrect colors. Entering and exiting a building usually fixes it.
- Music Issues: Some Gen 4 tracks may not have enough sound channels, leading to partial playback. All tracks are still listenable.

I was really looking forward to this one but so far it’s been a huge disappointment. I’m at my fifth badge and so far: the story is extremey underhwelming (literally there’s so little happening it’s almost like any other gym-centered OG game), the advertised encounters with OG characters seldom happens (only May and Brendan and for like, seconds, you barely interact) and most frustratingly the developer seems to think making increasingly complicated puzzles and mazes will compensate for the lack of content. It doesn’t. It’s extremely annoying tho, to go from ice puzzle to forest maze to city maze to forest puzzle and so on. At this point I’m so tired from it I don’t even wanna play anymore, despite being so excited about it at first.
.
To make matters worse it’s impressive how bad the selection of pokemons are. Idk if the creator was trying to make it more challenging or something to select maybe the most mid, close to shitty, pokemons out there for the player to catch while literally everybody else: our rivals, gym leaders, random NPCs, antagonists and so on have good to great pokemon. I mean??? How does that make sense? Where are they catching them and why can’t we catch them too? There’s no reasonable in game explanation. And one of the antagonists even makes fun of us for it lmao wtf man
.
Finally, two things: the multiple game bugs makes it really hard to play too. As of right now (fifth badge in version 1.0.3) I cannot get/interact with any new dropped items because if I do the game freezes. I can’t use ANY repels or the game freezes. I cannot interact with certain things or guess what? that’s right, the game freezes! It’s maddening. Secondly, I’m really on the fence about this new “type”/status changes. At first I thought it was genius and just really interesting, but to be so for real with you, now it seems like another way to hinder the player (on top of the built-in inescapable level cap and the mid to shitty pokemons available to catch). That is because the opponents rarely ever get any of the new changed statuses while we (the players) almost always do get them. On top of that, some of them are so unbelievably over the top that it halves the HP of ur pokemon in one go, which is crazy. As if it wasn’t enough that sleep are now used twice as this new “frightened” status which although is supposedly a “may” stop your pokemon from attacking, it 95% of the time does. At this point just outright say you gotta heal it, like a sleeping pokemon, otherwise you won’t be able to attack at all. It’s frustrating, and honestly shows how unpolished the game is, ’cause beyond all the bugs, the very new changes advertised as something fun haven’t been properly adjusted to make a good gameplay, instead of an annoying one.
.
I’d like to finish with positives though: it’s a beautiful game, I really enjoyed the tilesets and choices for characters looks/outfits. The battles – ignoring what I’ve said above – are also reasonably challenging without being too hard (for normal level) and I do think the map is well designed as well. It has the makings of a great game, but it’s not quite there yet.
Well wonder trade exist for a reason i gyess
How to do berry blender quest without link?
It can’t clear this. (TxT)
1.0.4 has nwo been released.
Which emulator should i play this? At this moment i am playing on John gba but everytime my magnemite try to learn new move game freeze
Please update, 1.0.3 has been released and fixes a ton of game freezing bugs.
Updated 1.0.3 version with bug fixes available. Please update. The latets is on the discord.
I mean 1.0.2, my bad.
Having to fight a Rotom on like the third route when most of your encounters so far (Rattata, Spearow, Paras, Woobat) are weak to it or can’t really hit it at all, is just bad game-design, I’m sorry. Not in a mood to overlevel my Popplio or Geodude just to get to the first gym.
skill issue niqqa
Do update 1.0.0 is out.
There was an update yesterday for this
The game just had a full release
I’m stuck at the Quartz Cave after the second Gym, how do I go to Cobalt City?
There was a hot fix that was dropped yesterday. 🙂
There is a bug when hitting the evolving level not gaining any XP and can’t evolve
This game is great!! But the evolving bug is really annoying. Anyone know a fix?
I encountered a bug at the first gym where none of the thread routes lead to the gym leader. I tried every combo possible and it’s a neverending loop, as I couldn’t even get to the second trainer even. Maybe I’m just REALLY missing something, but it feels like the gym puzzle shouldn’t be nearly this difficult for a first gym, so I have to assume it’s a bug.
Ok I think I fixed it. That was weird. I had to exit the building, save and restart the game, went back in and now the top left thread that leads to second trainer doesn’t send me to the bottom anymore, but to the correct spot. Anyways, beat the gym leader, and hopefully this helps anyone that encounters this bug.
I am way pass that. There is a bug on Mindaro Forest tag battle. Your 4th and 5th pokemon will duplicate the 2nd and 3rd pokemon whenever after the tag battle. There is a bug on Vanillite after capture. Make sure to save then reset the game. A bug on Reseda forest when you cut a tree. Missing No. Will show, make sure to save from time to time.
Ur mom can tourmaline deez nuttz niqqaaa
Please update celebrations. Delete classic version, and add there new game. Static Yellow

This game is actually pretty nice.
I just wish I could play in hardcore mode without needing to spend an hour for my entire team to level-up ONCE, essentially requiring me to spend like 10 hours per route and hours before each and every mini boss fight, and there are tons.
I do love the game. Story is nice, characters are nice, MC designs are cool, moreso the girl tbh… And as an emerald sequel, it’s got that certain level of coolness and desire to play it. It’s not just the same old same old remake, vanilla+ extreme randomizer, difficulty, bloated 1000 dex emerald decomp pret crap. It’s more of a thoughtful, curated selection (: And even with it adding I believe sound type, it’s not too extreme. Idk what other types it’s added. Just that I think. It’s very well-implemented. And the new Eeveelutions are baller. Especially the one for the new Sound type, and also the Dragon and Poison eeveelutions! And new eeveelutions in romhacks are just so hit or miss so they’re either not in there at all, or the designs suck 9 times out of 10. This is that 1 out of 10 lol.
But the GRIND. It’s just so unnecessary man 😫😭
And it’s only one difficulty above easy/normal, with the only other difficulty being Insane or something (So 3 difficulty levels total)
Just… man. Ugh
I’m glad it’s still being worked on tho, as a game I picked up a few months ago. So many romhacks just fizzle out in these stages. When it finally reaches 1.0, that’ll be the best day ever. 😆
Just want to let you know pokemon Tourmaline get new update today. Hope you can update when you free. Stay healthy and thank you
updated it
Thank you so much
Game crashes whenever a Pokémon evolves
Everytime I white out I keep respawning in xanthos city, sometimes thw game crashes if you speed up to long, there is some encouters with missing no and bad eggs. kind of annoying but not enough to deter me from the game
I keep having this too and it is pissing me off <3
I Love This Game but this Game have So much Bug and Crash I am waiting for next Update and I am not play this game right now why because this Game Crash in my phone please Update and fix Bug and Crash
these starters are kinda butt so I quit
I’ve noticed a few bugs. The biggest one that’s has me stumped is the green tower puzzle. “Gather the stones”, not a problem. Except for the bottom right corner one literally can’t be moved to the place it needs to be moved too
Man I was really enjoying this, loved the designs, the Echo type and the new region! But every time I try to evolve a Pokemon, it freezes 🙁
Very fun hack, and enjoying it so far. I have been noticing the bugs that have been addressed. But I’d like to point one out in particular that a couple of the forms/fakemon/megas I’ve caught have bugged the game upon entering the dex entry screen, but thankfully I was able to save before it froze entirely. Not sure if that’s related to the emulator speed up stuff but something to point out.
I hope you will consider releasing more Pokémon ROMs with English versions more frequently. The community excitedly awaits each new release, and more frequent updates would offer enormous joy to fans like me. Thank you for your devotion and hard work in making these cherished games come to life for us.
Is there an exp share in game? Or is it old school
Is this a demo only? I got a message saying thanks for playing the demo.
Using Pizza boy, nidoran males evolution freezes the game.
Also tried on my boy, trainer battles freeze the game also # definitely use save states !
I have to agree with the other person that evolving causes the game to freeze with no means to continue. This will make it nearly impossible to play the game as I don’t want to grind endlessly just to defeat trainers. The starting selection of Pokémon is already not that great, which isn’t necessarily a bad thing as it forces you to work with new Pokémon, but the evolution issue really needs to be addressed as it seemingly isn’t just the emulator. The crashes are one thing but not evolving kinda defeats the purpose. Otherwise I do enjoy it a lot.
Continuously encountering bad eggs and it crashing the game:/
Do any cheats like rare candies exist in this rom I’ve noticed the ones for emerald do not work for this rom and grinding is going to make this a long boring game and not focus on story as much as I need to get my levels up thanks in advance
Yes!
I like that fakemons are available, but to clear something out i do like a pokemon game that is canon more than fakemons but i don’t wanna lost the chance to catch all fakemons as well, so my advice would be to put the fakemons in a different world.
For example,have you ever played silent hill?
In the mirror of silent hill you will enter the world of horrors where your worst nightmares come truth
(Basically a big scale Freddie krugger)so how about you put that in the FanArt Rom?
If i where you i would make a world like that with the fakemons and instead of the mirror i would put kanto ghost pc AND DIGIMONS TOO 😱
(No, seriously, would be a great idea to add digimons on the ghost pc or just one to see how the players react, digimons vs pokemons √=v<k yeah!)
Anyways, im gonna give it a try but remember, don't put the fakemons in the pokemon world, pokemon fans won't like that so keep them in the ghost pc and then enter the fakemon world from that portal
Nigga make your own hack then since you have so many bright ideas
