You don't need to delete .cfg's, only if you want a clean reinstall tho or some major changes in new RA need a fresh cfg (which happens rarely afaik)... But mostly you can either replace .nro and updater everything inside RA (assets and other stuff + cores) or replace everything manually (without deleting your .cfg's obv), so it's up to you.is best practice when upgrading RA to delete and replace everything or simply the .nro file?
I'd love to be able to keep my settings so I don't have to reconfigure everything. but if proper procedure is delete and replace, I'll do that.
p.s. And besides that, retroarch files ship without any configs or saves that could overwrite yours, so just don't delete your .cfg's if you don't want to reconfigure everything (preferably just back up everything you don't want to lose, that's an obvious advice)
