I'm quite thoroughly confused about this. I uninstalled my old MIOS and installed MIOS v4 via Wad Manager. Still, Action Replay is recognized by the disc channel but just boots back to main menu. I've tried GCBooter, but it just sends me to a green screen then back to the main menu. I've searched other threads, but most of them entail people that have success with MIOS v4. Any help at all?
