Well, I recently used Dop-IOS Mod to install both IOS60 and System Menu 4.0U. However, whenever I try to load Animal Crossing City Folk, it asks to update. So what I figured I would do is download and install IOS38 for Animal Crossing trough Dop-IOS, but I had a few questions first. 1. Will I need to reinstall IOS60 because of this? 2. Is it necessary to patch it with the Trucha Bug and ES_Identify? 3. Even if I have IOS38 installed, will I need to disable disc updates through PreLoader? 4. Does PreLoader require a ES_Identify'ed IOS38 or IOS36?
