this keeps happening to me, i have formatted it at least 4 times now, but when i try to start a game, this happens. also, apps don't show up in the homebrew channel. i clicked 1 already and selected usb. thanks in advance!
My old sd card works, and still does, but when I formatted a new 256 gb card to fat32, it wouldn't show anything on hbc. as in the title, exception dsi occurred when I selected USB drive / sd card.
