I'm new to 3DS moding, I just did it today. I saved one of my other games as a rom, and it worked perfectly. But now I can't load into my cartridge version of Mario and Luigi: Dream team. I've been through the wiki troubleshooting steps, I cleaned both the cartridge and the port on the DS. I've run the gm9 refresh "verify file" prosses multiple times, and it has said verification success every time. The installed version of the game also does not work. I don't know what else to do, advice would be appreciated.
I followed the guide linked here to mod it, had no issues. The only other things I have done are add a custom background with anemone, and install TWiLight Menu++ and dump an original ds game and its save file to there and test them (which all worked correctly).
