yeah but imagine the possibility to boot the Emulator OS!! then choose your emulator to play and if you have internet connection you can update the setting, drivers import new drivers etc! or through the programming the Os programs the cpu clock automaticly for best compatibility of the emulator in modern systems... im dreaming a SteamOS that adapts o anyone pc!!! that has the repos to download any rom to play, and finaly that is so light like the bios of any console handheld or not! check the bios of ps3 for example, it boots quickly and through the bios boots in the game!! NO services more than the needed!!!! like the windows that drains you the raw cpu power or the ram! imagine one mother system that can update its core (in the hdd but reads from the ram)and if you choose then your emulator it forgets the mothersystems and pass to the end software-emulator (basicly os inside os) like the ps3!! loads the bios>play your game and you can close the game anytime easyly and return to the bios again to choose ather app!! (Mother OS > Bios Emulator[ps3, ps2, psx, etc]>rom[any game])
