A few days ago, I picked up an iPega bluetooth controller from Amazon. It seemed to work with Retroarch perfectly fine, but after a few hours of use, I started to realize some problems. First, it’s impossible to open the Retroarch menu unless the back button is mapped to open the menu. If you do this, Retroarch no longer accepts any inputs whatsoever, and I have to use a task manager to force quit the app. In game saves have stopped working on all cores, and the app has started deleting all save states when the app closes. Occasionally, no Android system keys will work at all, forcing another task manager kill. Since I use the emulator mainly for Megaman games and handheld RPGs, save states are a must for me. Any way to fix this?
