Yesterday, I successfully used the latest 3.0 build that WhoAmI? released to upgrade my backup O3DS to 9.2U and then downgrade the MSET to 4.x. Today, I want to do the same to my primary O3DS (which I currently dualboot between GW and rxTools 2.6), but I have a question that needs answering before pulling the trigger. Will the regular GW 4.x ROP work with a downgraded MSET, or do I have to use the 4.x DG ROPCustom.txt option to run the Launcher.dat? If it's the latter, how exactly do I set that up?
