if you want to paly GBA/SNES games,then dstwo is your best choice, it comes with gba/snes emulator,updates are quick, and it was also the best slot_1 card, if you are in the market for card that with powerful features and can play GBA games and ds games,then dstwo is right for you.
And you could also go with an R4 + Ez 3in1. You'll also get perfect GBA emulation and all DS games work well with WoodR4. however, that means you have to buy another EZ 3in1.
Supercard dstwo is currently the best gba flashcart out there as far as I'm concerned,it can run GBA , SNES and DS roms SMOOTHLY, almost 100% gba game compatibility. I ordered mine from http://www.thegamerdepot.com/supercard-...ids-p-152.html. Shipped within United States, took about 3 days to get here.
If you want play GBA games on your NDS/XL , then you can use dstwo or other flashcart,such as r4i gold, acekard 2i and so on with ezflash 3 in 1. But if you want play gba games on N3DS or DSi,then dstwo is your only choice. For DSi and N3DS dont have slot_2 to insert ezflash 3 in 1 expansion , dstwo comes with GBA emulator and you dont need buy any extra things. So personally suggested you buy dstwo,you can use it play both gba/nds games on all nintendo console with all firmware version.
