Like I said: I don't provide those addons and have no idea about them, please ask addon author.
Hey you're right,i mixing things you are the creator for the port to the sx05 devices but recently i found a mod from you build that has by default the retroarch and the emulationstation installed and fully working, but is outdated build 8.0.7 with old builds of retroarch and emulationstation so when i found your build 8.1.8 i upgrade but retroarch stop working same as amulationstation....them before a search on net i try to make this back to working with your new builds but without successs
