Here's the video of me trying. Quality isn't great but I had my phone in one hand and the 3ds in another:
@FakuMotaFaka : Well, I'll probably ask for a refund if I don't end up using the GW card. I'm pretty disappointed about it to be honest.
@Quantumcat: Ok! I'll give it a shot.
I do have more questions though:
1. If I update my firmware, won't it automatically update to the latest version of the firmware? If so, don't I risk getting a version who is too recent? I want to be really sure here because I don't want to end up getting stuck.
I'll wait for you guys answer before updating since I don't think there's any going back to previous firmware version after that.
Meanwhile, I'll read the guide, thanks! Very helpful community.
