Bios doesn't work?

[brunotrevisan]

I'm trying to make systems that use bios like pcsx and opera work, both always give the following errors:

Is there any configuration that I'm not including?

I guess this seems to be a bug from the official build of RetroArch, could you confirm is the Opera core working properly at web.libretro.com ? If not, that means we might need to try to compile the core by ourselves with Emscripten (and this still does not guarantee that the core will work as expected, since the bug may come from the core itself).
