Rosetta is not supported in current systems. Since 10.7., I think. Classic, which provided the ability to run Classic M68K and PPC binaries, had it's last release in 10.4. It wasn't supported in 10.5 and it never run on Intel Macs. Not to say, that both these technologies are limited hacks compared to proper platform-independent bytecode ala Dalvik, ART, Java or CIL.
