I have a USA N3DS with 9.0sys and 9.5 emu.
For the most part your program works fine.
Have a few games that can't seem to update, expecting because they were cryptofixed.
But what I am here to say is this:
I have Ace Combat Assault Horizon Legacy + on my GW card, it's the European version. Download updates, but apparently it doesn't apply because it keeps saying it has an update. But when I launch the game with your program loaded (even if you have all the options set to off), you can not access the nub or extra keys in the game. I had to reboot to get them to work in the game. I wonder if this is a problem with any other games, or it's because I'm running a European game on a USA system.
It's not a big deal, but thought I'd report it all the same. Thanks for the program, it's nice to actually go to the eshop on my N3DS.
UPDATE: Checked other games, nub & buttons seem to work fine in them, just appears currently to be this one game and I think it's my only european game I have on my system. Never found the USA version of it.
