I'm sorry if these are stupid questions, but I just want to make sure before I give this a try.
First off, I have the eShop blocked via router to prevent getting an update nag, since I don't have an EmuNAND, hard mod, or anything. I don't mind removing the block, but wanted to make sure that accessing the eShop in this way won't cause me to get the update messages.
Secondly, I just want to update some installed games. Is there anything special that I have to do to do so? I've never gone on the eShop before, having only gotten my N3DS about a month ago and it was on (and still is) 9.0 firmware.
Finally, I have a few homebrew programs installed and Ninjhax set up. I'm fairly certain that I will, but will I have to undo Ninjhax in order to set up this?
