Yes, you can but it has to come with a charger, a stylus, and the DS has to work
You can simply get them from a game store or of the Internet
If the stylus is broken, just buy some new ones, you can buy around 3 or 4 of them for £1 ($2) from online websites.
You can use any type of stylus and it won't scratch the screen. I recomend the one your Ds came with or if you lost it buy another one. You can also use a stylus that comes with a touchscreen phone.
You mean the DS stylus? Why would GameStop give out the DS stylus for free? Short answer probably not.
The iTouch doesn't come with a stylus, and I've read it's not meant to be used with one either.
you can use your pen or your finger as a stylus.
DS Styluses can be bought as DS accessories from many electronic stores that sell video games. They can be bought individually, or in packs of at least three.
The best way is to keep the stylus in the stylus slot and then keep the DS in a sealable DS case. That way, it will not slip out and it will always be where you left it. Other options include buying a bigger stylus that is easy to find.
For touching or writing on the touch screen.
