Hacking Homebrew Project MHXX/MHGU Save Manager

[DanteFeltzDeLeon]

What exactly happens when you try to save?

I fixed it. Before, it said the SD card wasn't found, so I couldn't save. But I tried other methods, and now I'm playing my MHGU save on MHXX. I'm very happy.

Ahh ok, glad you were able to get everything working!

I'm sorry, I don't know. It might be better to ask in the thread for the custom quest editor.

Fexty is currently developing a CQ editor for MHGU, but its not quite finished yet. You can check here.

I also have a github wiki for all things mhgu modding here

Yes, nearly all the DLC Palicos from both MHXX and MHGU are included. There are not enough slots to include every single one, so I chose to exclude some that don't have any unique skills.

I see，thanks. In the future versions，would you consider a new feature that add more export options for choose DLC contents? Such as option A:all the unique skills DLC Palicos; B: All the MHGU DLC Palicos; C: all the MHXX DLC Palicos.

I'll take that into consideration, but may I ask why you wouldn't just want all of the ones included? Just curious.

v1.4.0 Changelog:
- You can now manually select which DLC Palicos you want.
- In the DLC Palico Menu you can see information for each, including origin and special skills.

Sorry for the sudden message.
I'm creating custom quests in MHXX 3DS(JP).
I used this app to convert the system file from MHXX 3DS(JP) to MHXX Switch(JP), but when I check it on the Switch, the custom quests have reverted to regular quests. Is there any way to fix this?

Hello, the converter replaces all event quests with the target version's due to incompatibilities between MHXX and MHGU. Unfortunately that does mean that any custom quests will be replaced. However, if you just want to directly convert from MHXX 3DS to MHXX Switch you can append these bytes to the beginning of your 3DS system file:

00 00 00 00 00 00 00 00 04 00 00 00 00 00 00 00 14 00 00 00 74 EE B2 36 0C 00 00 00 88 1D 48 00 00 00 00 00

Thank you for providing me with this information.
Sorry for asking such a basic question.

No need to apologize, please let me know if you have any other questions!

You are an absolute CHAMPION, I had been struggling with a crash dump issue on my 3ds because I had converted my switch save to 3ds and I couldn't open the event quests list without crashing.
Finally resolved it by taking my MHXX converted save file to MHGU again and then after launching it on switch RECONVERT it back to MHXX and its working perfectly now !

Thank you so much !!!!

Glad to hear it!! Yeah, event quests are unfortunately incompatible between XX and GU, which is why you were seeing crashes.

Does this also transfer dlc quests? I have all of em and just wanted to know if they transfer with the save file.

It will not transfer the quests you previously had, but will add them all in on its own. This will only affect things if you had custom event quests added.
