I installed IronFall 2 days ago, using the old eShop and it worked first try! It took a while to download, but I now have IronHax working on my 10.3 O3DS I got after IronFall was removed off the eShop :P
Did you use the eShop or the Old eShop in homebrew launcher?
If its not working and you use a custom launcher (like grid launcher) use smea's default launcher.
The Japan eShop will NEVER in a million years work on userland (ninjhax2.x).
It could happen with kernel access but I don't think you have kernel access
If you had kernel access you could just install the CIA of that anyway :P
He said he's on 10.3.
Just get Ninjhax or OOTHAX using a save dongle, or hope for browserhax 2.0 or another exploit.
Lots of other people are in the same boat as you, so just wait and eventually a new exploit will come out. probably
Works well, but, it does not display eggs, and make it if your on a Old 3DS/Old 3DS XL or 2DS to not have ZL and ZR as they can't use that.
Why don't you also let you name the Bank Boxs like in the real Pokemon Bank
