Ok. I just shot the videos, but there are a couple things of note before the video gets edited and goes up:
1. System Transfer DOES NOT WORK. It will kick you back to 4.5 just as stated earlier in this thread. You can access the eShop and buy from it and download, but transferring is a no-go.
2. For all of you having problems with freezing going into Gateway mode as I did, I found that you are REQUIRED now to hold down the L button when selecting "Nintendo DS Profile". If you just do it the old way, it will not go any further. Also, you will NEED the Gateway cartridge in the system to boot into Gateway mode. I'm sure that's the "anti-clone" we rumored about.
3. Really important, so this is going to be in bold:
UNLESS YOU ARE DUMPING YOUR CARTS, DO NOT USE YOUR PHYSICAL CARTRIDGES ON THERE! YOU WILL LOSE ALL YOUR SAVE DATA ON THE CART!
I put this in all bold and big because this is a major problem! Luckily for me, I did it with a cart that I'm just going to play again because now I can play it in 3D instead of 2D on my 2DS(Zelda: A Link Between Worlds). When I put the Zelda in to test if it can run physical copies in classic (normal) mode, I found that my save data was mysteriously missing, even though I was right at the Dark Castle (the last one I had to beat). I thought it was an issue with Gateway reading the save on the cart, but sure enough, when I popped it into my 2DS, there was no saves present. My saves were erased off the cartridge.
So, I'm editing it now, but I'm telling you all and warning you of this issue.
