Hey Jimmy. I hate to threadjack but I'm brand new here too. I just ordered a r4i gold for my 3ds. From what I gathered from your posts, I should be able to update my 3ds to the latest firmware (the one that added 3d video, etc) and the card will still work but I should wait until I receive the R4 and update that first? If I run into any problems, do you mind if I bother you for some help? I had an iedge card for my DSI XL and it was a pain in the butt to figure out how to flash but I got it eventually, now that I'm switching to a new kind of card, I don't want to tear my hair out trying to get it to work. Hehehe.
