I have a US 3DS with Luma/A9LH, and I installed a crypto fixed cia of the US Rhythm Heaven Megamix, which works fine. I set up a friend's Japanese N3DS with Menuhax/Luma, and all US version cias work just fine -- except that same Rhythm Heaven. I have region/language emulation enabled, and I created a locale txt file using the game ID FBI tells me it is, all to no avail. It always freezes on a black screen requiring a hard reset. Any ideas?
