or does no one play on WIIVC?

Yes, marginally. The SNES runs at approximately 60.1FPS whereas the WiiVC runs at 59.97FPS leading to a difference of approximately 14 seconds over 90 minutes. Also, the WiiVC version uses the US 1.1 version which means you will have a slower experience due to text as well as none of the time-saving minor glitches (mirror block erase, item dashing, spin speed, fake flippers).

That said, WiiVC is a perfectly acceptable platform to run on, and the run on the US version is still quite fun to learn.
