I can´t use commands apt-get and i can´t compile/add sources of emulators

I can not compile or download emulators sources as I can download and / or compile emulators under Lakka in Rpi2.

Any alternative method?

Hello, yes Lakka is not based on debian so you can’t use apt-get.

You can clone lakka git repository, and package the emulators you want using the package system of openelec, and then compile your own image.

But this require some unix skills.

i try compile libretro-super but this is the result:
