Thanks
I actually found out it was because I was using an alternate boot manager which causes Luma3DS to run out of RAM, and unable to boot the DS games.
I updated my A9LH/Luma3DS with 11.2.0-35 -- however, it seems now that my DS Flashcards boots with a blank screen. Both DSTwo and Gateway blue card aren't working within Luma3DS. Is anyone else having this issue?
