Finally managed to put CFW on my 3ds!! everything works fine! what are some things I can do with a modded 3ds? thanks

Yes, you can update games normally, even if they were downloaded with freeShop. You can also update games using freeShop.I am in the same mode, I can't believe the patient Lacius had with me, and thanks to him I manage to do cfw to 2 3ds,
I didn't want to make a new thread to ask this question but I download mario maker from freeshop, but the games wants to update. So how was the game not the latest from freeshop?
Also, I wants to update from eshop, is that safe to do?
can I update games downloaded from freeshop by letting them connect to eshop?
I never have make 3ds eshop acc either!!
what is my options?
