Cores crash and boot to main screen

Im using the new retroarch 9 for ios 9.0.2. For the most part games would load fine. After an update a few days ago, n64 wouldnt work. Even with load recent. Worked fine for awhile. Also GBA, nes nestopia, also boot me while loading games. I never did have any luck with snes cores. Currently the only cores that work are mame2000 and atari stella. I tried to reinstall retroarch, delete and reinstall and no luck. Frustrating. And help would be appreciated

Me too! Yesterday i finally got it working with N64 and Playstation emulators. Even support for my mfi controller kicked in and i was so pumped! Then this morning i updated retroarch via cydia and then right back to crashes and nothing working. Im on ios 9.0.2 iphone 6s plus. Why does it do this?
