Currently the best cards for playing ds games are r4i gold 3ds and supercard dstwo, if you want to choose one card for your 3ds console. i would recommend you choose one of them, which one is better, which card you should buy for 3ds and ds consoles, supercard dstwo or r4i gold 3ds, this post will send the advice.

Both of them are working great on your ds and 3ds consoles, both of them are working great on the latest 3ds V8.1.0-18, but they do have different features, supercard dstwo is the best card for its features, it has a lot of extra features which other cards do not have, such as real time save, real time cheat, slow motion, play gba games on your 3ds consoles, all those features, the r4i gold 3ds card doesn't have. for r4i gold 3ds card, it is a best card for playing ds games and enjoy the normal features. it has very good game compatibility and can play nearly all the ds games.

So if you want to recommend one for you, it really depends what features do you want, if you just want to find a r4 card for playing ds games, get the normal features, r4i gold 3ds card of course is the best. but if you want to play gba games, get all the advanced features, supercard dstwo is much better. and supercard dstwo is also much more expensive for its features, nearly double than the r4i gold card.
