I fully expect there will be times for destruction and rebuilding from scratch knowing that this is a beta. I have spent a lot of time house cleaning, rom renaming and, obtaining media for the emulators and welcome the wizards and automated reconciliation of my ROM library. Until this is final product, it sits alongside my version 1.5.1 which allows me to use the system and the switch to testing the new HS2.0. My guess is for you there is a folder, perhaps hidden that is holding on to settings for you.
