So I've been scouring the internet for a couple of hours and I can't really find the answer that I'm looking for and I'm hoping that maybe I can get some help. If this was previously went over before then I apologize. I recently bought a DSTwo+ flash cart. I loaded on the OS, the SNES emulator and a few ROMs. I loaded it in my New Nintendo 3DS and it worked fine. I turned it off and tried loading on the GBA emulator with some roms. Put it back in and now it won't read it. Took it out and put it in my other NN3DS and it didn't read the cart again. I turned it off, turned it back on and it loaded and I played roms on it again. Turned it off and a few hours and came back later and now it won't read the cart again. Is there something wrong with the cart itself or is it something with the system, firmware or OS? Anyone have any idea? I've tried re-formatting the SD card and putting the OS on again and no luck so I'm not too sure where to go from here.
