There is also now one more location to find Moon Stones (you all can probably guess where).

Thanks for the answer but I still have no clue what is that place, a little hint maybe ? XD

Also, I think I know where to use GS ball now, it has to be a place where I have to complete Hoenn dex first right?

Hi Skyofblades; Im really enjoying your romhack so far, Ive already beaten most of the stuff in the postgame, I just have one question, my Mew is disobeying me all the time in battle, is this a bug or have I screwed something up (because I also cloned it but neither of them is obeying me). All the other legendaries are "working" properly. Im quite puzzled tbh. Anyways great hack, this disobeying Mew is the only odd thing Ive encountered while playing your romhack, everything else is really top notch, anyways keep up the great work mate, cheers !

The new area is where you'll be able to find one of the extremely rare Pok?mon all the way at the bottom of the Pok?Dex, and it's very, very far from the Hoenn Region.

For the GS Ball event, the location is somewhere accessible after defeating the Elite 4 and using Mystery Gift (no Dex requirements). If you have the GS Ball this location will already be available now.

That's really weird, it shouldn't be happening as far as I know. I did make some changes to the script to allow it to have a higher Shiny rate, but I think this may have resulted in changes to how the game generates it (it uses 'setwildbattle' in the script now instead of 'setvar', otherwise the Shiny hack wouldn't work). I'll look into it, but it could mean that I may have to put the script back to normal.

Did you use any cheat codes of any kind to reach/obtain it? I heard somewhere that this can cause it to happen. If not, you could send me your save file if you want and I'll reset the flag and fix the script so you can catch it again. I'll upload a patch for the script here once I've made it.

I've been quietly following this hack's progress for a while now and must say I'm eager to see it completed. However, the reason I'm speaking up now is due to this talk about the disobedient Mew, because I have seen this phenomenon in another popular ROM hack before. I don't know if this will be of any value to you, but the ROM Hack Pok?mon Glazed (or at least, the version of it that I played) also had an obtainable Mew in it that for one reason or another simply would not obey me in combat. I felt compelled to bring this up considering the same bug is apparently occurring for the same Pok?mon in a game that is using the same ROM base.

I also feel compelled to mention that there was an NPC in the aforementioned hack that would force a Pok?mon to be obedient, which is what I eventually utilized to get around this issue in-game.

Again, sorry if this doesn't help, but I felt it might.

A good way to send it would be to upload it to MediaFire, Google Drive or Dropbox, etc. and then send the link to me through a Private Message. Another way is to upload it in your post as an attachment, though that would also make it available for every other member to download if they see it here.

Thank you, it does help since it reminded me of a different way to fix this problem.

Nintendo apparently did this intentionally to penalize those who get Mew outside of official events, and it looks like they also structured its script in a particular way so as to allow it to be obedient if you get it on Faraway Island. Though as mentioned before, this had to be changed for me to give it a custom Shiny rate. I see that Deoxys has a similarly built script, and probably had the same restriction placed on it as Mew did. Apparenty it can be fixed by triggering some flag in the RAM, which must be why a script run by an NPC can solve it in-game.

For everyone having problems with Mew disobeying in battle, I found a patch on this page here that fixes it in the ROM: https://code.google.com/archive/p/pokemon-randomiser/downloads

Look for "Pokemon Emerald Mew Fix.ips"

Also I found a bug in Sootopolis City that causes you to basically take control of another sprite on the map if you enter/exit a a menu while near the Cave of Origin (in this case the guy blocking the cave entrance) which can be inescapable if you don't have a move like Fly to leave the map. Below is a patch that not only fixes this problem, but also does the following:

1) Switches the Espeon/Umbreon evolution method, effectively making it function the way it should (Espeon = day, Umbreon = night)

2) Adds a little bit to the Raikou event that basically helps to warn players to save their game before going further so it won't be so bad of a surprise.

3) Fixes the new 'bone-pile' tiles in the desert so that they do not overlap the Player sprite.

4) Gets rid of the random sprite issue in Lilycove's PKMN Center.

5) Fixes Mew's script so that it obeys after being caught, but if you already did the event then just use the patch above to bypass that problem.
*Note that this fix also removes the higher Shiny rate for Mew and reverts it to the normal 1/8192 chance*

6) Allows you to obtain the current iteration of the EV-IV scanning item (at the Abandoned Ship, in place of the Scanner). The script and actual feature works as intended (once you do the sidequest), but its name and appearance are a bit of a prototype right now so if it seems strange then you guys can give me some ideas if you'd like.

Here's the Bug-Fix patch: http://www.mediafire.com/file/q5f12r1p7pfomkt/CE_BugFixes_08152018.ips/file
*Be sure to only apply it to the current release of CosmicEmerald*

Hi sky Im almost done with the post game so far, but I have 2 questions, 1) where do i have to go to catch Celebi or better said where do I find the Celebi event ? I already got the GS ball, but cant find the event anywhere.

Second question I have is, what is the time frame for catching Mewtwo (im playing on a PSP so day and time are pretty off), because a few days ago I was shortly before midnight (ingame) in the right place, but nothing happened.

Just used the new patch to check out the new IV/EV base item, I think it works pretty great, nice job with its implementation ! But I guess some people just wont find out that they have to speak with the scientist in slateport to make it work, maybe a hint or some other clue should be implemented to be sure that really everyone knows how to make it work, or just give the player the already working scanner from the get go.

Great job and keep it going !

Celebi is in a special post-game location you have already been to if you have the GS Ball. I don't really want to spoil the surprise, but if you still can't find it just send me a PM and I'll let you know where it is.

Mewtwo is actually a past-midnight event, so you'd have to wait just a little bit longer before it should finally show up.

Thank you for the info about the new item! I did try to make it take the place of the original Scanner which you normally bring to Capt. Stern in exchange for the Deepseatooth/scale. Since Clamperl now evolves differently, I figured it was best to just do it that way to keep that sidequest relevant. I'll list how to get it in the main post when the newer release is ready.

Thank you! Though unfortunately, Gallade is not in this game.

Unfortunately we can't be sharing ROMs here, so what you need to do is find an English language Emerald ROM somewhere, for example by searching online. Once you have the game, then use something like Lunar IPS to use the patch I uploaded here.

I changed that event, it now has a Pok?dex requirement to go with the new content in it. The Locations Guide has some info about it.

Wow! This hack looks pretty good. Hey, do you know how to add event pokemon in the game? Like in the overworld. Like most legendary pokemon these days? I'm making a pokemon emerald rom hack because I can create a better post game with it but I want to make some pokemon like volcarona and just be there with no meaning in the game except to be caught later. I'm trying to make events like that. Can you suggest anything to put those in the game?

To add event Pokémon, you can use Advance Map 1.92 and a scripting program like Xtreme Script Editor (XSE). Navigate to an event by locating which map it's on in A-Map and then open its script address in XSE to see the way the event works. From there you can make your own, with parameters of your choice.

As for events to suggest, I'd say just do whatever you want with it. Things that you think would be cool to have in the game, go ahead and try to create them.

I love this game, and think it is one of the best ways to experience gen 3. It looks great, and I would easily play it over the original Emerald. However, I have one single and very tiny gripe. I am unsure of the location of Surskit in this game, as it isn't normally found in Emerald, and I looked all over for it. This is a minor issue, but still one I found. Please let me know if there's somewhere that you can find it. Thanks!

Hi jokeb, in CE Surskit is found on Routes 102, 114, 111, 117, and 120 in ponds (Surf), but the chance of finding it is 1%. In hindsight, this actually seems to be way too low of a chance considering that the pond encounter rate itself is also pretty low; so for the next release I will increase its chances to 4%. In the meantime here is a patch to increase it, since it might be about another month or so before I can really make more progress on the update. The patch also removes it from Routes 111 and 120, since it isn't there in the original game (put it there to mimic R/S's layout). I see it also normally shows up on 119 in grass during swarms, but right now it is still swarm-only.

Here's the patch:
IncreaseSurskitRate/BootScreenUpdate Patch

EDIT: Patch has been updated to reflect some planned username changes and fixes the incorrect version number ingame from May-15 back to May-24 (ironically, the bug-fix patch is where it came from).

@Everyone, I will attempt to include a PSS patch along with the next release as an extra.

Any update on the physical/special split patch? I love the fact that this Emerald hack doesn't include all the later-gen features, but a couple of quality-of-life changes (like the optional PPS patch) ? and perhaps also an optional patch for the Destiny Knot (or Destiny Knot-esque) breeding utility to make passing on IVs easier ? would go a long way towards making this awesome hack even better. Thanks for all your hard work!
