No you dont when you put it in a screen thing will come up.
No, you can't.
No, you cannot
hacking is illegal, but if you need to play homebrew and downloaded game roms on your ds purchase an R4 or an M3 hack card you can buy on eBay
It could be and action replay because the action replay might be one DS card and the game you are going to hack is the other DS card, so that's 2 DS cards.
No...Unless you have a DS Hacker who can hack previous saves. P.S. If you do have a DS Hacker I recomend not using him.
You can't. You would need a Usb storage card and a Rom and Emulator that can run on a DS. And even to run that you would have to mod or "hack" your DS to run the emulator.
you have to lvl them up on the ds card then copy them
You cant
DONT!
No, you cannot play PlayStation games on a Nintendo DS using an r4 card. There is no device that allows these games to cross play.
by an action replay ds/dsi (you can downlaod cheats for ur ds with it)
I do it by using action replay DS. A product made by datel that allows you to edit gameplay. It also works on many other DS games. Also comes for some other systems
