My console is an Old Nintendo 3DS XL, version 11.13.0-45U. I have the latest version of Luma, which is v10.2.
Nope, didn't apply any cheat or patch into the game. Yes, the game is from the same region as the console, and I updated it right after I installed the cia file.
Thanks, I'll check it out!
In the meanwhile after I posted this thread I was testing other games if the same error happened, and apparently the problem is only with certain games, that probably confirms the problem is with the cia file I installed or that I need a seed for the game right?
And, while testing with the game The Legend of Zelda Ocarina of Time 3D, another type of error occurred, and I had to reboot the console. After that, the 3DS wouldn't boot up again. I connected the SD card to my PC to check if there was a problem in the files, and the computer wouldn't recognize the SD card. That makes me think that the original problem was with the card itself.
Thankfully I have a spare 4gb SD card with all the files from when I installed the cfm in my console here, so at least it isn't all lost.
I'm gonna try to get another SD card and do another test with the games that occurred the error, hopefully it will be fixed if I just change to another SD card. If not, I will check out the post you mentioned and see if there's any seeds I need to import for the game. Thanks for the help!
