Earlier this week, Nintendo released NES title Balloon Fight for 30p as part of a trial period for the download service.
It's emerged that, like the Wii before it, the European version is in 50Hz, according to Eurogamer.
50Hz was the standard frame rate before HD, and meant that games would run with borders and slower than their 60Hz counter parts in other regions.
Interestingly Nintendo's latest handheld, the 3DS. runs NES and SNES games in 60Hz in Europe.
Virtual Console will fully launch after a Wii U system update this spring.
NES and Super NES titles will be available on day one, followed by Game Boy Advance titles in the near future.
Pricing for Virtual Console games will be the same as on the Wii, with NES titles available for £3.49 and £5.49 for SNES games.
Discounts will be available for games already purchased on Wii, with NES games lowered to 99p and SNES titles £1.49.
The scheme was announced in a special Wii U-focused Nintendo Direct conference that also revealed two new Legend of Zelda games, including a HD remake of GameCube adventure Wind Waker.
It also confirmed that a new Mario Kart and 3D Super Mario game would be playable at the E3 gaming expo in June.
