You can buy a flash card to play DS games, but there isn't 1 flash card to play both. Even so 3ds flash cards require you to downgrade your firmware if you are above 9.2. At that point you don't really need a flash card to play 3ds games because its better to install cfw.

 

My System version is "Ver.10.2.0-28E" this means that i need to buy an Sky3DS+? what about R4ISDHC (2014 or 2015?) it is good?
Where i can buy this? is there a good site, a real one?
Also it is better to install cfw (does is work online?) on it? it is working with my system version?

 

So with cfw can i play free games?
do you know any good tutorials for these?

 

So i can play free 3ds games on cfw also can i play online if possible?

 

Ah, don't use the words like "free games", let us rephrase that to your original games that you dumped yourself. Once you have such a file, you can install it to your sd and can perfectly play it online given that you update your cfw system version. My guide covers all of that.

 

ILeo, please, listen to what @wurstpistole says. He has made a very nice tutorial on installing CFW, you just have to find (here, of course) a nice tutorial on n3DS downgrade and you'll be good to go.
And yes, you'll be able to play *legit* 3DS games *that you have dumped yourself* AND play online. The nice part being that you won't need private headers if you're using a CFW and .cia files, *that you'll obtain by converting your *self-dumped 3DS roms*.

On the other hand, if you're unsure, just buy a Sky3DS+ or whatever. It'll (maybe) be a little easier to start.

BTW, I don't think the card on your screenshot will allow you to play your *self-dumped* 3DS backups.

 

Also i have another 3ds with v9.2.0-20DE it will work to install cfw without downgrade? also it will remove the parental passworld?
ps. all this time i was on my phone i didn't see your signature, sorry.

 

Now i need to know how to install cfw on v9.2, but i want only to play 3ds games, i don't need anything else just the games, just to power on the 3ds and choose the game i want to play, this is all i want ( i want to play games like Pokemon X and y, etc..) like cia? i don't know so much about this but i saw on a video there are icons of the game you want to play like R4 card for nds. can you help me guys? -thanks

 

Follow the tuts. If you want a zip file with CFW and a boot manager I can help you out. I just gotta upload to my mega
