actualy dstwo is the most powerful card, strong team and mines works perfect,not in very good shape? did you own a real one, maybe you should ask the reseller to change another for you or buy a new one.
It mainly depend on your purpose, if all you want is playing nds games or homebrew,then r4isdhc rts 3ds is right for you, but if all is for playing gba games, buy dstwo. Personally i like r4isdhc rts 3ds card, after all,it came from old r4 team, and the price is hard to beat. If you need, here is the usa based store i got my card from http://www.modchipwarehouse.com/r4i-sdh...s-lite-p-3.html
The gold r4i card does it's best to provide updates, but the only cart that has never needed a hardware update is the supercard dstwo. I got my dstwo card from http://www.r4flashcart.com/10-supercard...si-ds-lite.html I and love it.. no problems. I've also read good things about the r4i, and if emulation of gba/snes isnt your main objective, just nds roms.. then get the cheaper r4i.
I have to say,Supercard DSTWO is the best flashcart.
If you are not familiar with the DSTWO, you can get help
