if you get kicked back to the games' list, the emulator the games are using may not be installed. I know hakchi ce can do this, but regular hakchi doesn't seem to have the option, unless you do it via a command line. I only have issues like this with the snes classic. I've never had any error with the nes classic. the entire no intro set for the nes can fit on internal flash, but snes requires a usb flash drive if you want the snes no intro set. I even threw trials of mana on there. it works with the snes 9x 2010 emulator, not the official canoe one. I think you get a black screen otherwise.
