Ds Revolution

I havent got a Ds, and therefore havent got a single clue about them, but my girlfriends sister does, she’s 12, i noticed theres the R4? revolution, if i were to buy this for her, would all i need to do is plug the thing in my memory bay reader and put the games on it, and then she’s able to play them?
Or would i need anything else? sorry if its confusing, as ive only seen one once, im not even sure how this R4 would work, ANY guidance would be appreciated
Answer #1
yep. you need a memory card too but you might be able to get this with it
Answer #2
you put ds roms [like for emulators, u can get them at a roms website] on the sd and the sd goes into the chip. so u could have about 200 games on one ds card.
when u order it it comes with an instalation cd and if not u can download the 2 files from that disc from there website.
r4ds.com EDIT: there site is encountering problems right now, it says like bad request
Go here if u want to get any chip related to nintendo software
