I recently received a supercard dstwo from the affiliated shop and am currently very please with both the card, and the shop I got it from.
I have one problem though. While all of the games have worked perfectly so far Advance Wars Dual Strike while working causes the DS to play up in sleep...
Yeah it works great but it's the obvious Ds factor you loose from it it's not like playing atari games on atari because Nintendo actually use to give a reason to buy their hardware
I just like game consoles how they were intended to play if they have a unique enough reason to buy them anything else yeah just download emulation for it
