A member of the Neogaf forums has discovered that European Wii U Virtual Console games are running at 50Hz on both the console and the Wii U GamePad. At present the only game available is Balloon Trip, but it seems likely that other games will follow suit. The forum member points out that 50Hz is an antiquated refresh rate used almost exclusively by European CRT PAL televisions. NTSC CRT TV’s from the US and Japan refresh at 60Hz. There appear to have been a number of people complaining about this exact issue on the Balloon Trip Miiverse community.
