Every DS/3DS model will work the same with the DSTWO, so I suggest the 3DS since it's current gen and you can play the latest games. The AK2i no longer works on updated 3DSes.Oh yeah, forgot to mention that price doesn't matter at all. Willing to go with the most expensive or least expensive models. I just want the best compatibility - it's my ONLY concern.
The best DS for flashcards is obviously the DS Lite.
I would love a DS v5
(Phat DS with Lite firmware/screen)
I bought mine too early and got a V4.
I plan to get the supercard and the acekard. Which model DS should I get that has the best compatibility with these? Are there any gotchas I should worry about?
