Hi i have been reading on the forum and didnt get what im looking for. What flashcard do i need that is working well? Im using a 3DS XL Zelda bundle, lastest firmware Going to use it for these emulators: Gameboy/Color Gameboy advance Nes Snes If i missed some reading, just post the link and i dig into it. Sorry if this is a common question.
Then you should choose dstwo card, it can play GB, GBC, GBA, SNES, and DS Roms. It has the best available SNES/GBA emulators for DS and pretty much guaranteed compatibility with the latest 3DS firmwares. And i have tested my dstwo card from r4depot site, it can work on the latest 3ds v9.0.0 directly. The supercard dstwo is the best flashcart hands down. There are cheaper alternatives, I was hesitant at first, I gotta say...just get a dstwo and be done with any flashcart problems
dstwo is really the best r4 3ds card in terms of gaming, to any game fans, SC ds2 is the first choice.
If you're fine with not playing GBA rom on the console, then other flash carts brand can run the others just fine by downloading specific emulators for NDS to the cartridge which you can find through Google searching them. If GBA is a must get for you, then as Messywhite says, grab the SuperCard DSTWO.
