everythings installed from game starter but when i run emulation station or retroarch it asks me to quit kodi and when i hit "yes" ce 8.90.1 just reboots.
What are you running it on..is it a Rpi?
Before you try ES or anything else I would first make sure retroarch is working and launching the roms..as the other addons needs retroarch to work...If you r on LE8 go to retroarch settings and download cores.....then open retroarch and update assets..You need to get some roms to start with including their BIOS's..
ES doesn't work without roms in their appropriate folder
Sorry just seen ce 8.90.1 on your post...if that's the Core elec for amlogic don't think you r gonna make it work..this is for Raspberry Pi's and Generic
