The release of Mario Kart 64 on the Wii Virtual Console has been greeted with great pleasure by gamers the world over, but a problem with the memory pack emulation left it impossible to save time trial ghost data.

Ghost data enables time trialists to save their best lap times as a racing ghost, giving you something to race against next time you load up the game - thus making it easier to better your previous best time. Unfortunately the Wii Virtual Console version does not support this feature, with the game insisting that no memory pack is inserted.

Pro-G contacted Nintendo to see if there are plans to address the problem and it appears we're stuck with what we've got.

"Due to unavoidable technical reasons unfortunately it is not possible to save ghost data from Mario Kart 64's Time Trials in the Virtual Console version of the game," reads the statement issued to Pro-G.

For its part, Nintendo does say that it has "placed messages advising users about this before they download the game both when the Wii Shop Channel is first accessed and in the More Details tab on the individual game page."

It is, however, not the answer we were hoping for and raises doubt over Virtual Console compatibility with other N64 games that used/required a memory pack.
