Hi, I'm using a9lh v1. Luma is booted by default. I am also having a gateway card (gw.bin is of the Luma payloads), that's why I prefer to keep the Emunand. My SD card is big enough so I don't mind the extra space used by the Emunand. Some time (months) ago I could use the NDS flash cards from the home menu without issues while using Luma. I just tried this again after upgrading Emunand to 11.4 and Luma to 7.0. I have to check whether I also installed twllauncher in sysnand, probably not. Anyway, I never encountered the current behaviour that the O3DS switches off when starting the flashcard otr twllauncher. Could it be that somehow the O3DS fails to reboot in DS mode or something like that?
