'A fatal error occured' Cannot load MHXX on newer versions of Citra

I’ve had this problem for a long time now, I downloaded Citra to play MHXX and initially everything worked on Citra Canary without a problem. A few updates later, probably around version 1032-ish the game stopped working and produced the fatal error. I’ve backtracked ever since and I’ve been playing on Citra 972 which has been working for me. I’ve tried version 1823 recently and the same issue still occurs.

I did not find anything wrong in your log file. Please wait for a moderator to assist.

It is because Citra got more accurate. You should redump the game and the v1.4.0 update separately. You should be able to utilize Citra’s layeredFS implementation to add the patch files afterwards.

Download the patch from here: https://gbatemp.net/threads/release-monster-hunter-double-cross-english-ui-patch.465296/

You should be able to extract the 0004000000197100 folder from the patch into the \load\mods folder, provided you have installed the v1.4.0 update.

Most users that have this problem usually uses a broken pre-patched v4 English rom they got from the internet which unfortunately is piracy and is illegal. I hope you are not one of them :stuck_out_tongue:
