https://3ds.guide is the way to go. If you haven't used it since 2014 then you were probably using the DS Profile exploit and you won't have to uninstall anything. You can use the same exploit to install CFW (MSET). To play the games you already have, once you have CFW use GodMode9 (https://3ds.guide/godmode9-usage) to convert the 3ds files to cia and then you can install with FBI.
Thank you for the help and response. My mind is all fuzzy what i had done in the past, but what you said sounds about right if i can recall. I will pick up the 3DS from my daughter and then have a better idea. I will read through the two sites so I wont ask all the normal noob questions, though I am sure i will have a couple.
thanks again.
(Just saw that i have been using this site for over 13 years! That is a lot of help given by gbatemp over the years!)
