ROM Hack RELEASE MHGU Save Editor

Syco2108 · Nov 23, 2018

I tried to make th Glyph chest XR but it couldn't find it. Is it not implemented or is there a new version of the editor?

The name was probably translated different form the japanese in XX. Find it on Kiranico's GU listing, then switch to the same page on the XX listings

I think it's called 'Battle Glyph Chest' in the editor.

Is there any way I could get my XX 33ds save into GU without using checkpoint or any other homebrew save editors on switch?

Is it in any way possible to "downgrade" my XX3ds save into a copy of generations, to then be transferred into GU with the official tool?
I'm totally fine if I loose anything that was XX exclusive during the transfer to Genarations.

If this is impossible, is there perhaps a save editor I could use to rebuild my XX 3ds save as faithfully as possible for Gen 3DS?

I've been looking around, but info on this isn't super prevelant, and tends to vary from source to source.

Any help is appriciated!

You need homebrew regardless, as Gen, X, and XX all save to SD. The best you're prolly gonna get is to dump your equipment and items boxes to lists (be sure to downgrade any G rank weapon/armor upgrades that were over the Gen HR limits), then use my blanked-out 100% Gen save and import your boxes, player name, HRP, and GCID. There is a MHGU editor that could convert XX directly to GenU (you'll need a genU save to feed it and switch homebrew access to get/inject the save), but you're kinda screwed if you have any JPN-only DLC quests downloaded or any of a specific 5 DLC items from Gen that aren't in GenU (Most are tickets/passes for USJ events that land near [and include] the Wonderful Pass when sorting your item box. Shouldn't be a problem on the items as your save is already XX tho)

alrighty, i'll just do what you suggested and reconstruct my save (minus g rank stuff of course) in gen with that 100% file you have.

thanks for the help!

Now that devmenu is back for 6.0+ users, can anyone dump the dlc files, or at least a save with all the dlc installed?
Are those dlcs stored at capcoms server? maybe dns90 would allow users to grab them legally

minkiz88 · Dec 4, 2018

I'm having issues with the last step. I've gotten the Generations copied to X, the upgraded XX. I successfully import the 3DS save to the program and have a fresh, dummy XX (Switch) save dumped. I just can't get the conversion. I click to convert to Switch and click on the XX Switch save but it just hangs on "Loading your save file... Please wait..." I've waited for about 15 minutes and have retried it 5 or 6 times. I see other people talking about having to edit out conflicting items, but if I've never actually played the Japanese versions, I don't have anything exclusive to it. Is there anything from Generations for the 3DS that would conflict with Generations Ultimate?

minkiz88 · Dec 4, 2018

I'm a dummy... The program says to load up a Switch XX save (can be empty). I guess this is a hold over from the Japanese version, you just have to load up a Switch version of Generations Ultimate to convert it! I spent hours last night finding XX for the Switch just to export a save... :/

Well, hopefully this might help someone else. Thanks so much for the program!

I was actually able to access Capcom servers even though I'm superbanned and download all DLC. I'm unsure if Nintendo would be able to trace your console by accessing Capcom servers but i assume if I can download all the DLC then others should be safe. If you don't want to risk that, I can upload my save for you a little later.

Great, I guess I'll try to download them as i'm probably banned too (and don't really care if i'm not)
as the dlcs are currently stored inside the save there should be a way to extract them or even create new ones and inject in other saves

Can you upload that save with all the DLC downloaded? It would be a great assistance if you could

I second this, please AeoxEternal if you can upload your save with all the DLC it will be a great help for all. Many thanks.

I updated Dawnshifter's MHXX save editor code to load MHGU save files. All I did was update filesize to match MHGU size instead of MHXX. Tested some item box save edits and it worked fine. Use at your own risk and backup saves!

If you don't want my exe you can compile Dawnshifter's code with my forked filesize edit below

changed code is-
MHXXSwitchSaveEditor/MHXXSaveEditor/Forms/MainForm.cs
Line 32; readonly int SWITCH_SAVE_SIZE = 4726152 + 432948;

https://github.com/Dawnshifter/MHXXSwitchSaveEditor

Update since everyone is asking
At this time you can convert your MHG and MHX saves:
1. MHG -> MHX (via 3ds .cia MHX Data Manager, I suggest moving to Character Slot 1)
Get cia or homebrew .3dsx file here
Yes, you need a hacked/homebrewed 3ds.

2. Import MHX save to MHXX on 3ds via game
You need MHXX (game or cia) on your 3ds. Open the game and import your MHX save.

3. Export MHXX 3ds save file using JKSM or other save data tool.
JKSM found here
Choose to export ExtData for MHXX

4. Open the MHGU Save Editor I posted here, and convert the "system" file you just exported to Switch (click okay for errors or re-open exe if it wont load save)
Load your 3ds MHXX save file, select convert at the top then To Switch.

5. Import the new "system" file to your Switch using Checkpoint or other save data tool.
Checkpoint .nro file can be found here
Yes, you need to have homebrew running on your Switch

Attached my MHG converted save, it lets you import as new save (edit name, etc.)

MHXX/MHX saves may have extra data and cannot be imported as-is (try deleting special items if you can)

For help with Talisman editing (game and app blocks fakes)
my post in this thread

Your save works great so thank you very much.

Can anyone help me figure out what is causing my game to freeze. When i view my equipment box it the game will freeze.

I tried to load your 100% save and converted to Switch, but crashed the Switch.

ComManDerNomad · Dec 27, 2018

I'm having an issue. I am using my own legit MHGU save from a purchased copy of the game. I can load the save no problem after exporting it through checkpoint, but after i make any kind of change like adding armor it throws an unhandled exception when trying to 'save' or 'save as', i doubled and tripled check the armor i'm trying to add is legit and possible (not any kind of dlc). I have been able to use this tool before so i am not sure what has changed. I downloaded the exe you posted to the first post (not the github one).

I know why and I got same error.

There is fix - do NOT close the message saying "Loading your save file.. Please Wait.." so you have to drag this message to other place and click OK on "Detected a Switch or 3DS save", so it will disappear on own, so be patient.

Right, I do that, i only close the "switch save detected" window, and the "Loading your save file.. Please Wait.." window still closes by itself without my input, but it still crashes when trying to save.
Edit: playing around with it a bit, Basically i can make one change, and save successfully once, then it's crashes after trying to save a second time, even if i make no changes.

Try again? I had no issues with this editor, hmm.

Ask @Entoptical for help.

yeah its worth a try. use the original editor tool to convert to 3ds, then mine to convert to mhgu.

i think until someone figures out how to remove Japanese MHXX event items and quests there may be some errors though

Are the "Zelda Breath of the Wild" items also Japan only?
When not, which items are known to be MHXX only event items?
