Ash-Greninja Mod for Reborn, Rejuv and Deso

Hello, I'm also in the same boat of not getting this mod to work.

I downloaded a fresh copy of Reborn 19.5, then updated it to 19.5.34. The other mods I have are the allgen mod, SWM, and Decat. 

I copied the instructions from the main post, extracting the files from the zip folder and then moving the graphics and mods files to Reborn's patch folder. Afterwards, I tried using decat to change my starter to Greninja and check if the mod is implemented. I tried to use ability capsules to change the Greninja's abilities, but it only shifts between torrent and protean. My next test was to use decat to give me the old version of battle bond, and then i used the debug option of fighting two trainers to check if the ability would trigger. It didn't.

I also tried looking into the code itself, but I have no idea what isn't working, because I remember also using this mod in a prior version, and it working then.

Hopefully someone could help. I also looked at similar questions in the discord server, but I couldn't see any solutions.

did you try creating a mod folder in the patch folder then moving the .rb folder there?

I created a /mod folder in the patch folder as well as extracted the patch folder and merged it with allgen's /Graphics and /Mods folders. But I still yet to see that Greninja to change to battle bond using ability capsules or red-hots. They only switch between protean/torrent. Please help, I don't know what to do

I tried it without Allgen, seems like they're actually incompatible with each other despite Allgen's page stating they are compatible. Sorry for the inconvenience, man I wish it worked together

Ok so I got the opportunity to talk to @Fervis about the All Gen incompatibility issue, and the reason is that All Gen now overrides most of the pokemon object and battle code using the Mods folder, which means that the aliased methods in the "Ash-Greninja Mod.rb" file also get overridden.

 

The simplest fix is that if you're using this mod with All Gen, you just rename the "Ash-Greninja Mod.rb" file to "ZZZ Ash-Greninja Mod.rb", which will make it get loaded after the All Gen overrides so that both mods work.

 

This problem won't exist with 19.6 since 19.6 will have complete gen 9 support in base game, so overriding the entire battle code will not be necessary

Does it support 13.5.7

Make sure you're using the latest version. The error does not look like it can happen with the latest version of the mod

Hey I kno rlly late and everything but I got the mod for rejuvenation and the form doesn’t change like stats do and it has the whole transform animation happens but no ash grenija tho like it’s just base grenija. Don’t know what issue it might be cuz rn im running the latest 13.5.7 so idk man.

[Karvanha]

That sounds like you didn't replace the graphics probably? It's written in the download instructions

[Goobisdoofis]

P4 well I merged the files so I just assumed the graphics went where they were suppose 2 but ig not. Anyway how would I change the graphics 4 ur now cuz the mod works it’s just the visuals.

[Goobisdoofis]

Nvm fixed it and it was because I didn’t get rid of the previous png file. Sorry boss :p

Yeah, the v13.5 version of the mod will likely break if you use it with v14. However, I have updated the mod for v14, so you can just use the new version :)

[Karvanha]

I already said it above but yeah, the mod has been updated for v14 of Rejuv!

The download link has been updated with a v14.0.13+ compatible version of the mod. Redownloading and updating the mod will fix the issue (for updating you just need to do the same thing as when you first installed the mod, ie, drag and drop the patch folder into your game folder)

Thanks for the mod, its been working great. Though, is Greninja supposed to go back to normal after switching out? I get a kill and it transforms like normal, but then it goes away once I switch out and can't even re-trigger on KO.

You need to take out the mod, update your game, and reinstall the mod after that

The current patch is 14.0.20, you're on 14.0.0

So hi! I been using this mod for Rejuv, and I have my Greninja Shiny. So when I have defeated a mon, in a trainer battle, I never see the Ash Greninja sprite. I put everything into the mod folder, so what am I missing?

You're supposed to put everything in the patch folder, not the Mods folder, as written in the main post

I meant on the patch folder, my apologies! 

I follow after I had unzipped, put the icon and the battler on the graphics, int into the int and yeah... and still it just doesn't, unless it needs to be on it's own folder.
