Failed to load content IOS 7.1.2 pangu

when i launch roms, (tried PSx, GBA) it says that loading roms failed

People are having issues with pangu and A7 devices (iphone 5S) with PSX but GBA roms should load fine. If they’re not, you probably have an issue on your end.

for GBA choose the core Game Boy Advance (VBN NEXT) AND this is a fix for A7 devices like iPhone 5s, iPad air, and iPad mini retina. download this file and unzip it. http://www.mediafire.com/download/ey1dth9fyn6qubk/psx_for_A7.zip

just drop the two files: 1- pcsx_rearmed_interpreter_libretro_ios.dylib 2-pcsx_rearmed_interpreter_libretro.info to this directory > var/stash/_.Itmikn/Applications/RetroArch.app/modules or shortcut /Applications/RetroArch.app/modules

after that make sure to quit Retroarch then launch it again for the new configuration to take effect. you will see new core which is Playstaion1 (Non-JB)(PCSX ReARMed)

Anything like this to fix sega cd? Cause neither core is running - failed to load failed to load uhh
