Emerald Enhanced is currently a BETA game.
At any point, anything could break for any number of reasons. If you're not okay with this, then this may not be the game for you.
Also keep in mind that Emerald Enhanced is meant to be very challenging from the beginning.

Main Features:

The EMERALD ENHANCED dex:
We have a total of 684 pokemon in the game. This is thanks to Egg's pokemon expansion repo.
There are far too many pokemon to list here, so I have created a spreadsheet, which can be viewed here:
EE 6.0 Dex

Expanded Options

• Theme choices, light or dark for the user interface.
• Text Speed choices.
• Random route/battle music.
• Animation speed of HP and EXP bars.

Prestige Mode!
Every time you become champion and then start a new game, your level cap goes up by 25, to a max of 250.

Real Estate and Bank!
As of EE v 7.800, you can now open a bank account at the Frontier Bank, found in Mauville City. It can hold up to ¥2,000,000,000 pokedollars!
In addition to the bank, you can now buy, sell, rent, and move into one (or all) of 12 properties throughout Hoenn!
Note that you need to progress the Nobles faction to gain access to Real Estate!
You can find these properties in:

• Dewford Town
• Fallarbor Town
• Lilycove City
• Mauville City
• Oldale Town
• Route 119 (northwest)
• Rustboro City
• Slateport City
• Snowy Shore
• Sootopolis City
• Verdanturf Town
• Mossdeep City

Just look for the differently-colored signs!


More Starters!:
We now have 7 starters options, up from 3.
The options are:

• Duskull
• Aron
• Rhyhorn
• Skitty
• Sandile
• Nidoran (male)
• Tynamo

They have been adjusted to work as well as a starter would in a vanilla game, or better in some cases. This gives more variance to the
new game experience, since you'll probably be using New Game +


5 Modes of play:

• Normal mode scales your EXP and Winnings to the number of gyms you have beaten. It goes up by 25% per badge (12.5 in prestige mode).
• Easy mode is 4x base experience, for people who want to get through the game quickly, and aren't confident enough for harder modes.
• Challenge mode is a harder variant of my game, with custom rules.
• Hardcore mode uses special rules. No pokecenters, Marts can be used but it's more expensive.
  You gain less money and gain the default vanilla exp value. Fainted mons disappear from your party.
• Frontier mode takes you directly into the frontier. Choose a starter team with which to challenge the frontier, and earn BP to purchase new frontier pokemon to expand your roster.

DexNav!
This is a feature from gen6+ that makes it easier to find strong pokemon with hidden abilities or better IV's.
You can obtain DexNav after getting 6 badges and entering any town that has a gym.


Follower System:
Followers will help you in battles against the E4, Title Defense, and max tier gym leaders when they are following you.
The current followers are all of the befriendable NPC's and Minnie.
You can dismiss them anytime, talk with them to do so.
Each follower has a passive bonus that helps you on your adventures so that there's more value to unlocking and using them! (new!)
Followers can sometimes get a bit misaligned, to fix it open the Start Menu and press dpad left. This should reset their location to behind you.

Poké Ball Changer:
You can change the Poké Ball your Pokémon is currently held in by talking to the Ball Changer NPC.
She's located in the Lilycove Department Store on the 5th Floor.
To change Balls you need to pay 10.000 Pokédollars and have at least one of the corresponding balls.
This is also a Ball shop, so you can say No to changing the ball, and see the inventory of the shop.

Autoscaling Trainers & Wild Encounters:
On your first playthrough, everything is scaled to the number of badges you own.
On consecutive New Game Plus runs, the enemy mons will scale to the levels of your party.

Boss wild encounters!
You have a 1 in 128 chance to encounter a boss wild pokemon. They can easily be noticed as their names are bright red.
These pokemon have 31 in every IV and have their hidden ability. They get +6 to both defenses when the battle starts.

IV Perfecting:
You can get an egg with perfect IV's and desired nature by utilizing the Genetic Code Mapping System.

• You can consign up to 31 of a certain species to increase your Genetic Code Value(GCV).
• You can use the GCV to generate an Egg of your saved species. The species you generate will have IV's equal to the GCV in each stat.
• When you generate the pokemon, you will get to choose a nature.
• The generated pokemon will be an Egg that you have to hatch with the moves and ability of the first mon you consigned.

Visit the Training Center in Lilycove to get started. It's the left-most computer in the left room.

Achievements!
We implemented a fully custom Achievements system. You can access this screen from your Journal.
There are achievements for many things, including but not limited to: Each alternate ending of the main questlines, Scoring significant amounts of overkill damage, Exploration, and more!


GOLD Achievements!
There are a few achievements shown with Golden names and icons that will reward you a Master Ball when unlocked. Go after these hard achievements for those delicious master balls!

Achievement Powers!
These player-accessible abilities are passive effects you can have active, at the cost of Achievement Power, which you get by unlocking achievements. On top of giving collectors more to collect, this gives additional value to sticking around and playing through the game multiple times. You can get powers like increased movement speed, capture rate, prize money, and so on! Access this feature from the Journal.

Factions
There are 7 factions in the game that all NPC trainers are a part of. The Hoenn league and evil teams are not in this system. Each faction represents a group of ideals held by the member trainer classes.
There are Daily quests available for each faction, you only have to speak to any member trainer to obtain them. This will increase your faction standing. In addition, there are quests unique to each faction
that will unlock or otherwise give you access to a specific mechanic or feature. Presently, there is only Alchemy, obtained by doing quests and obtaining standing with the Outcasts faction.
A complete list of factions and their ideals can be found here: Factions Document

Re-Fighting the Elite Four:
When you fight the Elite Four again, you will get teleported to an alternate Champion room after you've cleared the E4. While you're in here,
you walk to the middle, like how you walk to your throne in US/UM. At which point a random challenger will approach you and challenge
you for your title. There are currently 8 possible challengers, and more will be added over time until I reach 16. This is how the
game stays once you've met the requirements.

Life Skills
There are 3 life skills in the game:

Mining:
Mining lets you mine ores. You can find things like shard ores to craft into evolution stones, metal ores to sell for money, Fossil ores to obtain fossils.
Refinable ores can be processed in the small mining cavern town near Fallarbor. You need 4 badges to start.

Botany:
Botany will let you harvest plants in various ways, such as cutting trees, or grass.
You are able to craft the things you find using recipes to create your own versions of various battle items.
You can get started with this skill by visiting the Slakoth Banana Farm near the Safari Zone entrance!

Alchemy:
Alchemy is an end-game system where you create very powerful effects that impact gameplay in a significant way, some craftable effects include:
-Damage Boost
-Defense Boost
-Regeneration in Battle
There are some other effects too, please explore these and enjoy tailoring your own experience!


Other notable features:

• The player performs HM functions without any badges or items. You can just swim, or pull out a tree, or smash a rock, or whatever.
• Persistent weather. When a weather move is used in battle, the weather will persist in the overworld until a map change takes place. Great for weather teams.
• Completely custom jukebox. Use L + R in the start menu to activate, R to skip tracks sequentially. The currently playing track number is
  displayed in the top left corner of the screen when the start menu is open.
• Remote access to the PC available when you complete a certain quest.
• EXP Drive item that stores some exp earned in battle to be given to a specific mon later. Or toggle earning exp in battle.
• Imprinter item, which works similarly to the EV Reduce berries. The consumable imprints you get reduce EVs to zero, rather than increments of 10.
• Waystone item, which replaces the HM Fly functionality. The waystone gives you more locations you can teleport to, including each of the 7 Frontier facilities.
• The entire frontier has been overhauled to include many new generation pokemon and strategies. Your skill will be challenged greatly.
• Contests now reward items from tables upon winning, rather than giving the same thing over and over again. Currently it's just balls, but this will be changed in the future!

New Game +
New game + becomes available starting from the first time you visit the Hall Of Fame.

• Only Pokemon in your PC Boxes are retained, including held items.
• Unique key items are retained.(Imprinter, EXP Drive, Remote PC, Forecaster, and the bike to allow both in the inventory at once).
• Dex progress is retained.
• When you start New Game+ you get to choose between Normal, Challenge and Hardcore modes.
• Upon starting a new game, enemies scale based on your average party level instead.

Here's what it looks like:



About Emulation Compatibility:
My game is a custom compiled version of emerald with major core code changes. My game will only work properly on emulators that are
accurate to real GBA hardware, or the actual hardware with supported flashcarts.

The only emulator I can confirm has 100% compatibility is mGBA version 0.7.3 or above. Note that some of these versions can be unstable, I recommend using the latest when possible.

Unofficially supported emulators (reported by players, unconfirmed by me)
* My Boy! Paid

Hardware Compatibility:

• Real GBA, GBA SP (Flashcart. Must have support for SRAM, flash 1mbit save file, RTC)
• Real NDS/DS Lite (Flashcart. See above)
• 3DS (Virtual Console, mGBA port, special flash carts)
• Nintendo Switch port of the mGBA emulator. You need cfw on your switch to use this.
• Presumably, if you can figure out how to inject it, Nintendo Switch Virtual Console as well.

Other emulators can work, but with limited compatibility. The most common issue is black screen freezes when transitioning to and from battle, and between maps.

These are not issues I can fix. Emulation accuracy is key here, and mGBA is the most accurate emulator available.

Discord

Please keep in mind that I only update this PokeCommunity post with information when I make major changes and release major revisions of the game.
If you want access to the bleeding-edge builds, you can join the discord and be informed every time I upload a new patch. I also discuss reasoning behind
my decisions, as well as take feedback there. I do watch this post to reply to anyone that might have commented, but I prefer if people join the discord.
Thanks for reading about my game!

If you would like to participate in polls for new features, access walkthroughs, and pick the brains of our expert pokemon players, please join the discord and say hi!

Get the game here:

The game is distributed in a patch found in this google drive folder: Emerald Enhanced
I have included the flips patcher for Windows systems in the same drive folder.

HELP WANTED

Currently, All of the scripting in the game is done by me, and it's the most difficult part of decomp development.
I'm looking for Scripters to help me with this part of the game. As you can see above, the game's content is quite 'complete'. All new scripting would be bug fixes and modifications the advanced systems I already have in place.

We are severely lacking in the Artist category. As you can see above, aside from the in-game UI theme,
there's not very much custom art. I'd like to be able to make the game stand out. You would be doing things
like re-skinning existing map tiles, and modifying existing overworld sprites. You may also be doing some
back-sprites for new followers and partners added.

Looking for Writers to flesh out questline dialogue and add some life to the characters throughout our world.

Please join the discord and ping a Community Assistant to let them know why you're there. Keep in mind that we have over 3000 people in the discord, so it may take a little while for me or staff to get back with you.
Thanks for your time!

This looks great hope it gets completed soon good luck

Thanks. I'ts an ongoing project, I don't think there will be a point I can call it done. As new games come out, so do new features that I might want to add to my hack, you know?

Hello!

First of all, I have to say that this hack looks very promising and I love both the design and the added features.

It appealed to me so much that I downloaded the game and began to document myself playing through in Nuzlocke mode. Everything went fine until I went up to 102 and began to battle the trainers. The game freezes in every single one of them, usually midway through the first turn.

At first I thought it might just be a minor bug with one or two trainers, but after avoiding all of them and proceeding to route 104, I encountered the exact same problem.

I had been looking forward to playing this game and am very bummed out that my hours of training have gone to waste.

If there is any way to fix this bug, I would much appreciate you let me know. (I am playing the game on a Macbook Air using mGBA v0.6.3)

Thank you in advance.

Could you give us an early option to max out our IVs and methods to EV train our Pokémon? It would be nice to have this in more improvement hacks as a quality of life change.

There are several emulators that have trouble with my hack, and like to freeze. I only officially support mGBA. I have been having a little trouble tracing this issue, but I suspect that it's a result of the idle loop optimization I included. The Optimization fixes a lot of animation hitches, and vastly improves maximum emulation speed (using the speed up function of emulators)

When you download the new patch, your save file should still be compatible. I'd also not recommend a nuzlocke. I admire your bravery, but I haven't even been able to progress through the game without getting wiped out a few times normally, let alone with the added challenge of a nuzlocke. The general point of my hack is to provide an augmented, more challenging vanilla experience, which is also what the nuzlocke challenge started out as, doing both may provide a tad... infuriating.

Generally, IV's are just luck of the draw. I wanted to include a way to view EVs/IVs but my knowledge of the underlying C code is not such that I would be able to easily implement this. For now, all I can recommend is saving and softresetting to get a good starter, and catching a few of the pokemon you want to use, to find the best one you can.

This does look very interesting. Will yiubbe adding More side quests?

Probably. I'll be adding things as ideas hit me or are requested/suggested. I do have the ev/iv checker and training center added now, which was mentioned or asked for by people here. Feel free to join my discord if you'd like up to date patch notes and to make suggestions for the hack.

How do I patch with Beat? I tried patching Emerald with it and I keep getting an error.

You have to patch a version 1.0 ROM of the game with my patch for it to work. How you get a version 1.0 rom is up to you, unfortunately.

Hello. Is there anyway to download this game? Would like to try playing this game. Thanks .

You have to have a version 1.0 Pokemon Emerald ROM. Patch your ROM with the Emerald Enhanced.bps file found in the downloads section, and play it that way. I would love to just give a direct ROM download, but nintendo and PokeCommunity don't like that, so I can't.

Do the new Pokemon have their correct cries?

No, and, jusdging by you asking that specific question, I'm guessing you either tried it yourself, or have heard talks of it. The only way to put the original cries in requires a much more in depth series of hacks to make it work out, and I'm not an expert. Sorry.

Just out of curiosity why does this use a .bps patch and not a traditional .ups or .ips? I also still can't seem to find a 1.0 emerald rom...which I'm guessing isn't the TrashMan version?

I don't recall the full technical reason why the ips/ups patches don't work, but the issue with those, generally speaking, is that they work on comparing differences between roms with the same codebase.

My romhack is not so much a rom hack as it is a fully compiled custom rom, so there is no longer a common codebase between my ROM and the original Emerald Version rom. BPS Patches work on any files of the same size, regardless of codebase.

Well, I started playing your hack and i do like what you've done so far but my biggest concern would have to be the color of the foe's HP bar. It's very hard for me to actually figure out how much He it has after a battle because the purple (or dark blue) blends into the custom health bar you made. Also, while picking my starter, I could walk into grass without picking my starter while Birch was being chased.

Yeah, it's because I removed the ledge that was normally there to block you and force you to walk into the grass. I took a lot of these out. Most people know to go to the bag, anyways. and if they don't, well, you get sent back home anyway. xD
If you're using a dark or night mode on your display, try reducing the strength of it, The Contrast for the HP bar isn't huge, but it's been fine for me. I'll look into adjusting it, anyways, since you pointed it out.
I recommend joining my discord to catch my latest features and planned features. I usually talk about them there. It's also a good place to post feedback.

How do you choose which difficulty mode to play at the start? The screenshot doesnt really show and I tried interacting with all things in the van

Just by walking out of it, the menu should pop up.

This game looks incredible. Only reason I haven’t picked it up is because there isn’t a way to control the IVs your Pokemon receive. I’m not saying you have to add a perfector, even though that is the preferred method, but updated breeding mechanics work as well. Maybe give the player the option to have an IV perfector? The challenge is deciding which Pokémon you want to use, including their movesets, not grinding for hours trying to get lucky with a system that spits out IVs randomly.

Sorry to barge in but does your ROM not work with the Cry Editor tool? It seem fairly simple to use, there's even a video tutorial on it on Anthroyd's channel (can't post links yet)

I mean, this is kinda how pokemon games have always been. I do have ways of instantly maxing out IV's, but that's incredibly unbalanced. Also, most attempts at influencing ivs results in a bad checksum on the pokemon, turning it into a bad egg regardless of what it is. Only programmatically setting them to 31 has worked for me so far.

Honestly, iv's only give you 30 or so points total to a stat give or take 10 depending on base values
You can accomplish more with EV's and nature, which can be influenced via Synchronize.

It would probably be a good option. If I was Binary hacking. I'm not, I'm using the decompilation project, which means each time i make changes, I compile a brand new ROM. Editors like this are not an option, cause I'd have to re-apply the changes every time I compiled, which is dozens to hundreds of times a night, when adding or testing features. Additionally, the reason cries can't readily be edited is because I'm using slots that were reserved for old unowns from gold and silver, but were never implemented since they didn't make them forwards compatible. These slots are all hard codedto have the same cry, and that's the cry they currently have.
