I just purchased a NDSL ... as yet unflashed ... so I like others here will be interested in whether any of these carts will allow download play to or from an older flashme'd NDS.
I would prefer not to flashme the NDSL if possible .... I've heard it's a bit harder than the standard NDS and I dont know anyone with another one that I can open should I brick it.
It's ridiculously easy. I've flashme'd 5 Lites and one original DS, and they were all a breeze.
