I'm not able to reinstall ninjhax on my Cubic Ninja retail cartridge after downgrade. It seems Cubic Ninja crashes everytime i try to scan QR code for 4.5.0-8E version...
Someone tried it?
Did you delete the savegame on the cartridge
I need to get ninjhax working on 4.2 now as well...
If it helps to know I downloaded a Smash Bros demo on my Japan 3DS around 8.1J and it's still there after downgrading.
Can you launch it?
