This thought came to mind recently after being indecisive on what to spend 1000 Wii points on. Is there any differences between the VC versions of the games, versus the same game in ROM form? I was planning on doing this for Genesis games (mainly because Genesis Plus keeps ticking me off), but what of NES and SNES, which I emulate. From what I gather, the VC versions are much more clean and load instantly. The ROMs, on the other hand, allow unavailable games to be played as well as other features (cheats, save states, etc).
