I'm pretty much a newbie when it comes to flash cards, I was told to buy one by a friend and I did from a website, and this was a long time ago. I don't have my DS anymore, however I have a 3DS and I was wondering if I could get it to work again (mainly to save me switching cards when I play different games). The information that I have about the card is as follows: It's grey with a sticker stating "R4 Revolution for DS (NDSL/NDS) It came with a 2 Gig Micro SD card There's no spring loaded method to get the SD card in. I believe this is the website for it: http://www.r4ds.me/ I'm guessing it's a clone and that it will not work on the 3DS but I wanted to make sure before I did anything... as I mentioned I don't have a DS to test on. Thanks for any help/advice, I spent a good portion of an hour reading through different threads on this website.
