First of all, this isn't GameFaqs. Don't bump your posts. It gets really annoying if too many people do it.
With that being said, the DLDI M3 Sakura can't boot NDS files. At the time, it was used as a media player for anyone who wanted an alternative to Moonshell, but now with the release of Moonshell 2.0, the DLDI M3 Sakura is no longer needed. You might as well just delete it off your cart.
