***Meant to type Flashcart each time not Flash Cards...my bad*** Hello all, I haven't been on this site in a few years now but was thinking of getting a 3ds here with my tax return and saw something about some flashcards and from what I can tell they are similar to that R4 cartridge back when I had my DS some time ago. Where you would slid a SD card in the cartridge and play games of that. Anyways is there anywhere to get any info on these. I have tried google with little to know help and was hoping would find some documentation on it here. Just wanted to know... Are there multiple kinds? Do they play 3DS games? What are the limitations of it? (Do I have to have a 3DS for some firmware) How well do they work? Do they even exists?
