It seems that I could solve my problem by granting write access to the following folders for the whole user group:
- /storage/.kodi/addons/plugin.program.advanced.emulator.launcher
- /storage/.kodi/addons/game.retroarch
- /storage/.kodi/temp
I don't think you have to do that to be honest..I don't remember doing that when I set mine..
If the roms run from retroarch they should run fine from AEL...it does take some time to setup all with artwork and get used to how it all works especially if you just started with emulation..
I just use retroarch for running roms..never scanned any rom folders from retroarch or downloaded artwork......just downloaded cores and changed few settings for audio and video and few other settings and that's it...
I run my roms from AEL or Emulation Station...both sharing same artwork from same folders...been some time now that I set everything and working flawless...when you r done make sure you have a backup cause it's hard work to start again especially if you have 1000's of roms...
