Getting a 3DS XL tomorrow at best buy (better late than never) does it come with an AC adapter to charge while I play at home? and a card to save data? feel like I shouldnt need to ask since this should be standard, but I had a friend recently buy a PSP (yeah, old stuff, I know) and it didn't come with an SD card, so he basically couldn't save any games.) dunno if this is just becoming a "thing" with handhelds, last one I got was the original fat DS long ago and it had all its cables, so idk.
Yes, you do get a memory card. It might 4 GB worldwide but I'm not sure. It's definitely that size in North America.
Whether or not you get an AC Adapter depends on which region's XL you're buying. The ones from North America, Australia and South Korea do come with an AC Adapter while the ones for Europe and Japan do not.
