From today there is an update in the Wii shop that finally fixes the scrolling glitch in Military Madness. There's also an update for Mario Kart 64 that fixes a glitch on the character select screen too.
Just go to the Wii Shop and find the game you bought then apply the update.
It's all very well that bugs are being fixed, but we were hoping for fixes more along the lines of getting Mario Kart 64 ghost data working.
The VCA wonder if one day certain games may be patched to enable wifi play. Oh mighty Nintendo, let it be!
