I own the real thing for most games I want so I never bought many VC games. Game Gear Shinobi on 3DS is the only one I bought recently since my GG is dead. M2 always does a nice job with the emulation and options.
I was disappointed with the C64 games on Wii. Instead of giving North America the versions it had back in the day, we got PAL ones running too fast. Sometimes I prefer sped up games but in the case of The Last Ninja, it makes the music sound way off.
