Hey. I suggest you give this a rest for a few months. We've spoken to RecalBox guys and we'll be getting support for the Rock64. The issue, as I understand, is that Lakka currently do not use SDL; the RecalBox build will use kms instead of fbdev and SDL 2 +. This will, among other things, improve the situation when using overlays and shaders. This work will surely, in time, also find its way into Lakka and other retro-gaming distributions.
Do also keep in mind the difference in time that the RPI (3) had for development and the Rock64 had.
Have you tried emulation on Android ?
[edit] Answering your question; take a look at this thread if you want to build your own RetroPie image.
