r4i gold 3ds deluxe is currently the best, the same team also make the r4i gold 3ds rts card and constantly working on and updating them. I got my deluxe r4i card from this resellers in the US http://www.r4flashcart.com/20-r4i-gold-3ds-deluxe-edition-play-3ds-games-on-3ds-xl-and-3ds.html you know US based reseller are very very few now.
mine is the 3dslink, very smooth in playing 3DS, i got it very cheap, whether deluxe or not, the most important is that 3dslink has the same function with GW
Yes, in some sense, they are. But now my R4i gold 3ds deluxe edition works all right, so that does not matter. It is quite cheaper than gateway 3ds. ( http://www.digimartz.com/r4i-gold-3...ds-games-with-r4i-gold-3ds-starter_p1215.html )
And is there any difference between 3dslink and r4i gold deluxe? They charge nearly the same and I know little about r4i gold. I haven't ever used r4i card.
