bsnes core DLC added!

We're happy to announce that bsnes has been added to RetroArch Steam as core DLC!

This DLC includes two cores, bsnes and bsnes hd beta. The difference between the two is that bsnes hd beta also includes experimental widescreen, gradient and windowing features added by DerKoun, who also originated the HD Mode 7 effects included in mainline bsnes"
