I have bought gateway and can play 3DS roms, however I just bought it because I will move to other NZ region (whose game is ridiculously expensive) with my US/Asia 3DS XL. DS games look more interesting at the moment.
the reason I bought a handheld is because I want to explore the homebrews since I don't play games so much during my younger days (just like I did with my pspgo) and see how far they can extend the handheld capabilities. anyway, thanks for the recommendation, I will look up for DStwo (have bought r4 for 10 bucks, wish I asked this before purchasing)
