Ok I uploaded updated source tarballs in the usual place http://depot.javispedro.com/nit/64/ , the mupen64 one [1] contains both source and binaries (including gles2n64.so).

"Port" notes:
- gles2n64 uses SDL-GLES: "apt-get install libsdl-gles1.2-1"
- it does not care about whatever resolution you put in there, and always uses fullscreen. it does care about the framebuffer resolution, so you can scale.
