I just bought a Sky3ds so that I could play the original SM3DL E3 Beta (sm_retail.3ds, sm_dev.3ds, sm_gateway.3ds), but no version of it will run. I've tried the .cia versions of all of those files as well, to no avail. A stock Super Mario 3d Land rom will work fine. Is there any way, Sky3ds or otherwise, to run this beta? The only way I've been able to run it is through the Citra emulator, which is too slow at this moment, and lacks sound.
