Squishy.

If you've been crossing your fingers for Super Mario All-Stars 25th Anniversary Edition in the expectation of it receiving a PAL-optimised conversion, you can unbend them and start using them to type vitriolic comments now – the package will not be 60Hz compatible.

Below is the response reader XD375 received when enquiring with Nintendo Customer Service:

We have now received a response to your enquiry from our European head office. Unfortunately, the European version of Super Mario All-Stars runs the games at 50Hz and not 60Hz.

If you're not sure why PAL 50Hz is a problem, our article Talking Point: The Virtual Console's PAL Problem could be enlightening.

Super Mario All-Stars 25th Anniversary Edition lands in Europe on December 3rd.

Thanks to XD375 for the tip.
