English-Patched MHXX not working on latest Nightly build, but does work on older build

Issue:
So I haven’t played Citra in awhile, and when I came back to it today, I saw that for whatever reason this game that previously ran just fine on Citra no longer does. I have not modified the game in any way, as I don’t know how to mod things at all.

What is stranger is that I do have a separate older build of Citra that has working cheat functionality on it, and the game runs fine on that older build.

But on both the latest Nightly and Canary builds it doesn’t work and I have literally no idea why.

Monster Hunter XX (JPN) (RF) v1.2 English Patch v4.3ds

Prepatched roms are broken, Citra got more accurate which made these not working anymore, redump the game “vanilla”(Japanese, and no update or patch on it) then patch the v1.4.0 game update then dump that as CIA so you can install it on Citra with File->Install CIA, then it will work.

Build 21.20.16.4821

Drivers are outdated too, you should update:

download win64_25.20.100.6373.zip from https://downloadcenter.intel.com/download/28289/Intel-Graphics-Driver-for-Windows-10
direct link: https://downloadmirror.intel.com/28289/a08/win64_25.20.100.6373.zip

then follow this guide to install it: https://www.howtogeek.com/343287/how-to-fix-the-driver-being-installed-is-not-validated-for-this-computer-on-intel-computers/

After you have installed that you can if you want update further(recommended): https://downloadcenter.intel.com/download/29127/Intel-Graphics-Windows-10-DCH-Drivers?product=88180 (download the .exe this time).

I can update the drivers like you instruct me to, but I do not have the ability to get a “new” file for the game. [Piracy isn’t allowed - Moderator Edit]

Will there be changes to Citra in the future to make prepatched roms work again? I cannot read Japanese so the native version of the game would be useless to me.

We cannot help if you pirated the game.

If you can prove it is running 100% on a real 3DS then it might get fixed, if it doesn’t work on a 3DS then Citra is just being accurate.

I cannot read Japanese so the native version of the game would be useless to me.

The goal here is to dump the game in its native form without any modification to the actual game itself and only add English patch to the v1.4.0 game update.
the “v4” English patch is also outdated, there is v5 now and even another patch that is built on v5. (i.e another person took dasding’s v5 patch and built upon it).

Welp then I guess I would have to go find an unpatched version of the game and english patch it myself.

I did once install an english patch for a different monster hunter game (MH2 for PS2), would the process of installation be anything like that? It was using some small program called PPF-O-MATIC v3.0, simple streamlined program that allowed me to just select the game file and patch and it did all the gritty details.

Patch instructions for dasding’s v5 patch can be found here: https://gbatemp.net/threads/release-monster-hunter-double-cross-english-ui-patch.465296/ You need to do method 2. By “UPDATE CIA” it’s implying v1.4.0 game update.

This is out of scope on Citra’s end, you need to ask for help in that thread for further support.

Alright, thank you for your help. I’ll post here if things still are not working right.
