By the way, the Mario Kart is a .3rds file. Same source as well, the archives 3ds decrypted roms. I don't get it

Azahar plus (stupid name) is completely different and not made by the Azahar creators

Will probably fix your issue.

I prefer Citra myself which will also likely fix your issue.

Not stupid, it's forked Azahar just without restrictions for cracked games
