[Vm-dev] Squeak VM port to Google Native Client

[Javier Pimás]

hi! We've already made it compile with PP 0.5, but it's not displaying
anything in the browser. Maybe it's the image or the browser version, or
something related to PPAPI changes. Which image and chrome version did you
use? Actually, we tried your live demo but it isn't working in our browser
either.

Regards,
 Javier
