I hope they at least make a version without GBA support. I almost give a damn about it. The games are so cheap. Why would you want to back them up? I guess you would have to carry them around, but who cares. Just get a bag to put them in. The expensive GBA support was a waste of money in my opinion.
GBAGI
Hexen DS
Heretic DS
All these (and more) require GBA support in order to work.
And, of course, tons of GBA homebrew.
But let me paraphrase a bit:
[irony]"The NDS games are so cheap. Why would you want to back them up? I guess you would have to carry them around, but who cares. Just get a bag to put them in. The expensive NDS flashcarts are a waste of money in my opinion."[/irony]
[sarcasm]So what's the use of an M3 in the first place, GBA support or not? The GBAMP can do everything you could possibly think of, oh, well,
except playing ROMs. But who needs that, right? And for only $25, even. [/sarcasm]
