Neverball was working in the original glshim project before ptitseb forked it to gl4es. (Not to discount the significant work he's put in since, including the ES2 backend)
My bad, I completely forgot they worked off of a fork.
Did you ever try Neverball with glshim, though? Why? I'm the current maintainer of Neverball, always very interested in Neverball-related stuff.
When I was working on the Emscripten port, I tried a bunch of GL-to-OpenGL ES libraries. There were a few. I might have tried glshim, but not sure anymore, that was a couple of years ago. gl4es was the only one that worked without any obvious visual glitches.
