Avoiding gl4es was the fun part.

With patched sdl and fullscreen we avoid an extra copy from the compositor also, so play is smooth.

Only stuttering comes when a transparent text window appears. This could possibly be fixed by hacking those textwindow textures to be non-transparent.

Maybe someone with a good camera could showcase mario64 for youtube? People like to see shiny stuff render fast.

Currently fighting with a PPSSPP build which could run playably on Omap4, but it insists on using libGL.so / gl4es? Maybe sdl2 does. I'm trying various things.
