This is largely a “quality of life improvement” type of ROM hack, and does not alter the main storyline. It retains all the features the original Emerald has, but adds several things to the mix to make it more fulfilling and fun to play. Remember those days when myths like going to the Moon after a certain number of rocket launches/weeks were a thing? Several things like that will be accounted for, but with some changes/twists to how they are done. There is a moderate increase in difficulty (not really big, just aimed more towards veteran players), but there are rewards to compensate.
Only a select few newer-generation features have been added, as I wanted to keep this hack’s gameplay as faithful to the pre-2007 scene as possible while still adding a few of the newer games’ improvements in function. However, I might add in a few newer-generation Pokémon as special appearances/events sometime in the distant future. Apparently, expanding the PokéDex could cause the game to require its own exclusive saves only, but I think that will be OK as long as one does not plan on using this hack’s saves with the regular Emerald (or vice-versa, I think). You may want to also keep in mind that if I happen to release an expanded-Dex version at some point, it may not be compatible with a save file from the regular version of this hack. Regardless, I will not stop updating the regular one and will still release it as well if that is the case. I would also try to find a way to make the original saves compatible with the new one.
Δ The PRNG glitch has been fixed by re-incorporating Emerald’s unused PRNG system
May need someone to check this one, just to fully confirm that it has been implemented properly
Δ All 386 Gen 1-3 Pokémon available
A New Evo Stone that evolves Trade-Evo Pokémon
More Roaming Legendaries, events, different sprites, etc.
Some events based on Day/Night/etc and/or game completion status
Pokémon from different PokéDex sections have their own battle music (based on region/availability in-game)
(i.e. Encounter a wild Pidgey somewhere, it will play Kanto’s Wild Battle theme; while Sentret has an exclusive Johto Wild Battle remix)
Most events/Legendaries have signature themes too (i.e. Suicune and its Crystal battle theme), though related ones share themes
A special Event-Shiny somewhere
Check the Game Corner prizes in Mauville City for a few surprises
Mirage Island can now be reached in a much better (and honestly much more sane) way than in the original R/S/E
Available on Sunday mornings after capturing 180+ National Dex Pokémon (The National Dex always includes Hoenn Pokémon as well)
Δ Special Event Tickets are available via unlocking Mystery Gift and finding the MG Receptionist upstairs in all Pokémon Centers
Obtaining the Nintendo Event Tickets in this hack uses the real Mystery Gift scripts that legitimately unlock them! 🙂
Mystery Gift is unlocked the same way as normal: Fill out the questionnaire in a PokéMart with “LINK TOGETHER WITH ALL”
How to obtain them this time:
Eon Ticket: Become the Hoenn League Champion
AuroraTicket: Defeat Steven at least once
MysticTicket: Raikou, Entei and Suicune all defeated/fled from or captured (Like w/Crystal Version’s Ho-oh, but more lenient)
Old Sea Map: Get 180+ National Dex captures
Δ Day & Night System (Early-Morning, Morning, Day, Afternoon, Twilight, Evening)
Affects battles too, and will eventually affect music on maps in a future update
Δ Graphics have been altered in many different areas/aspects (nothing too fancy, but it is an improvement IMO)
(i.e. Meteor Falls looks very different now, many menus are new colors, trees/caves different texture, etc).
New Battle Backgrounds based off of HG/SS’s and recolored to match CosmicEmerald’s altered environments
The tiled indoor trainer battle style and the Champion one were designed by me using Paint
Edited Rayquaza’s backsprite so that its lower ‘fin’ points backwards instead of oddly forward
New (but still similar) Title Screen!
You may find that certain maps look quite a lot different than they were previously
Δ Upgraded B/W Repel System (lets you choose whether to use another and which kind)
Δ TMs are reusable
Δ All Pokéballs (except Safari Balls) are reusable until capture
Are slightly less common and cost quite a bit more for balance’s sake
No more worry about resets, savestate-abuse or running out of chances to capture a Shiny
Δ Your Pokémon receive EXP when you capture another, like at the end of a normal battle
Δ Pokémon’s Natures have color-coded stat boosts/drops
Δ Rough Skin Ability Fix (from Gen IV)
Δ EVs cap at 252 instead of 255 (in order to not waste remainder points)
Δ Somewhat steeper difficulty curve
Storyline-based/secret trainers are stronger, Event-Legendaries stronger, etc), but nothing really insane
Δ Running While Indoors
Δ Final Trainer Card is no longer Gold, but is ‘Platinum’ (well, not that literally, but it’s totally different than before)
Δ Upgraded EXP system: All Pokémon directly participating in a battle will receive full EXP, not half unless you use EXP Share to avoid having to switch them out. This allows you to have more options for how to train
Δ Steven can now be re-matched daily, and depending on when you face him, the Champion Battle theme might play (like in R/S)
Δ It is now possible to “turn off” the random calls on the PokéNav (except for the scripted ones in the story) by using Prof. Birch’s machine in the lab
Δ The clock in the player’s room now lets you know what the day of the week is before showing the time (there is a minor bug on the Playstation Portable, see below in the bugs section). Because of this, it can now help you know if the in-game day is correct when you want to do a special Event!
Δ The Safari Zone’s expansion area is now split between nocturnal and diurnal Johto Pokémon (North and South, respectively)
Δ The bed in the player’s room can now be used for sleeping, and possibly investigating a ‘nightmare’
Δ Lamps on maps that have them now have a lit/glowing animation during night hours
Mt. Chimney’s lava is also lit up at night
Δ Features 4 new RSE-style music remixes I made (3 from G/S/C), + 2 hidden Crystal-Version tracks from the original
Δ As another special feature for this ROM hack, Rayquaza, Mew and Jirachi have a 1/200 Shiny chance (if this one doesn’t sit well with you guys, I can remove/modify it if enough of you ask me to)
Δ A few Legendaries’ movesets are very slightly different, for event battle purposes. Levels on most of them have increased, so be prepared. Some are also holding rare berries, and by researching these berries’ tag info you can get an idea of who has which berry. See if you can steal them with Thief before they are used in battle!
Also, the roaming Legendary Bird Trio now have a catch rate of 5 instead of 3 to make things a tiny bit less frustrating
Δ There are rumored ‘prehistoric’ Magikarp on Faraway Island, battle them a bit to see what is so special about them!
Δ Cave of Origin is now accessible permanently after fully completing the Jirachi event
Suggestions for changes to features/requirements for events or items are welcome.
Planned Features and Ideas:
Δ Special Add-on Patches that allow you to customize the colors of certain things such as clothing and the HP boxes in battle (which are currently purple)
Δ Wild Double Battles (depends on if I can somehow port it to this game)
Δ EV/IV Display Screen (I have now tested it successfully. This will be in the next release, likely as a Key Item!)
Δ A watch-like Key Item that lets you view the current day and time (It actually works. Might be in the next release, not sure if it’s a good idea since it makes the Player’s Room even less useful)
Δ Eventually have the ‘indefinite berry replanting’ feature working, it would be an amazing thing to have
Δ Turning the Altering Cave into something more interesting someday?
Δ Maybe some additional graphics updates
Δ More Music Editing
More Day/Night-based song switches
Δ More time-based weather changes on maps
Δ Make it so Deoxys’ form can be changed via regular overworld script
There is already a way to switch between Speed and Normal, but I’m not sure right now if it can be done via scripting. Unless I expand the Dex, it may be limited to just switching between Speed and Normal form using a patch.
Δ Consistent (but maybe not total) decapitalization of all-caps words and phrases
Saving this one for last to avoid any possible complex errors while I work on things. Honestly, not sure if I want to even implement this or not.
Known Bugs/Issues (If you find any more, please let me know!):
Δ PokéDex text shifting glitch involving “EXP when Catching Pokémon” upon level-up
It’s a bit annoying, but definitely not serious or game-breaking. There is currently no solution for this that I can properly use yet, but when I do then this should be an easy, easy fix.
Δ There is a feature implemented that is supposed to allow berries to replant themselves indefinitely but it is bugged. I have no idea why, and the game basically ignores it completely so it might as well not be there. It’s also quite a pain to test, unfortunately.
Δ When Wally catches his Ralts at the beginning of the game, the battle background defaults to daytime when he exits the Pokéballs Menu. Unfortunately, I have no idea how to fix this one, I’ve tried but it’s probably going to take a bit more than dealing with scripting commands.
Δ Some overworld sprites used to be incorrect and needed to be switched out, but I think I may have gotten them all now. If you find any more weirdly-placed sprites like that, let me know so I can fix it as soon as I can. It’s not a game-breaking problem or anything, but it just looks kind of bad.
5/31/2018 – Just found out that you may or may not see a random Lapras sprite in the Lilycove PKMN Center. For some reason it appears there as one of the game’s dynamic sprites, and so never showed up in the map editor as a Lapras. Not sure how to fix it right now besides removing that dynamic sprite from that map, which could amount to removing whatever original feature it was intended for (don’t want to do that though).
Δ Not a problem with the hack itself apparently, but: For those using a GBA emulator on Playstation Portable, the game may show an incorrect day of the week. In my case, the in-game day was behind the IRL day by one. For example, if it was Tuesday IRL, it said Monday in the game when I used the clock. This does not happen to me when I use VBA, however.
Δ Coming into Route 111’s desert from the top side may result in a cactus (new tiles) appearing glitched. It’s harmless and even fixes itself as soon as the map is refreshed, but I plan to address this next time the game is updated.
Δ Minor typo: “Do Not Call List” abbreviated as “DNCR”, since at one point I was going to call it the Registry instead of the List. Will be fixed in next update.
4/6/2017: Touched-up a few Wild Encounter lists, Locations Guide was already updated for it.
4/17/2017: Put in the rest of the customized Wild Battle Music feature, so that it actually works in-game now. Also gave the option for Tyranitar to have the Intimidate Ability, so it’s not limited to Sand Stream. Also changed weather on a map to fix a tile priority issue. Updated Locations (Clefairy and Paras).
5/2/2017: Fixed the sprite issues Lightblitz7 pointed out, complete with updated scripts. Switched out the Pokémon Center theme in Evergrande City’s bigger Center for the game’s hidden “Crystal” one.
5/17/2017: Upgraded the Title Screen a bit (finally)!
5/18/2017: Fixed a minor defect in the new Title Screen and altered it very slightly.
8/9/2017: Johto Pokémon from the National Dex now have their own battle theme, further upgrades planned for Lugia and Ho-oh theme(s). Events that required Hoenn Dex completion now have been dialed down to only needing either 150 (Lapras), 170 (Legendary Beasts), or 180 (Mewtwo). Also, the Link Stone is now called the Plasma Stone instead. Box Wallpaper variation hack applied, see a later post of mine in this thread for details. Planted berries should now stay planted and recycle themselves – no more 9-day limit! The EXP system hack I explained in a post later in this thread is now applied. New Locations Guide released as well.
8/11/2017: Got rid of an annoying bug I just found.
8/26/2017: Updated Locations Guide with info about Mirage Island.
5/12/2018: Finally, another HUGE update with several bug-fixes and loads of improvements and new features. PokéDex-based requirements have been overhauled again, be sure to read through the above sections because there have been many, many changes. For the updated encounter locations and Legendary/Event requirements, see the new Locations Guide.
The secret islands have gotten some updates this time around, especially Navel Rock. Those of you who enjoyed G/S/C may especially like this release of the game.
Jirachi and Celebi are finally available, and those who already completed their Hoenn Dex to meet the previously way steeper requirements get first dibs on Jirachi (and probably Celebi too. Heck, everything is probably available to you at this point). Great job!
5/14/2018: Holy hell, I just took another look at some of the Underwater maps, and they were outright terrible because of many, many misplaced tiles. I quickly fixed that mess (yes, it was painstaking) and everything is nice and clean now. Also:
!Δ! Bug fixed: For those transferring over from a regular Emerald save file, if you had already done the New Mauville sidequest you were not be able to catch Raikou, and some other events using the game’s old flags wouldn’t work if certain items were already picked up. I felt this had to be fixed ASAP before too many of you got the 5/12 update. Those events I mentioned were created at a time that I thought the game had no safely usable extra flags, and that had only recently changed. All events made after 8/11/2017 used newer flags, and now everything after this fix should be working. If anything is still going wrong with this, let me know and I’ll update it again.
5/15/2018: Wow, this has been a frustrating experience but everything wrong with the events is FINALLY fixed. Someone was still having issues with a couple of events, and when I checked out the scripts there were crucial parts I missed in the last update. So, I went and thoroughly tested every single event I added and can now confirm that each one is working. Bear with me guys, I know it’s probably annoying but I’m really trying here.
5/24/2018: !Δ! Bug fixed: The black-screen problem concerning Magikarp has now been fixed. There are several minor tile fixes on some maps in order to make them look better than they were.
Also, the Cave of Origin is now accessible permanently after the Jirachi event is completely finished (must talk to the girl in Mossdeep again and show her Jirachi).
NOTE: All new features I put into the game since last year’s August update will now be added towards the bottom of the “Main Features” section above, from earliest to latest.
