Hardware Cant get VC to run at 480.

[dazzi]

Hello I know this has been well very likely asked before but how do i get my Virtual console games to run at 480p?, in particular the n64 ones, the reason i have started this thread is because the way that everyone posts, go into operations guide hold A+2+Z until you hear a chime, well its not happening to me :S.
Any ideas?
My wii is a 4.0E Australia/PAL
The games im trying to run at 480p are;
Zelda Ocarina of time
Zelda Majoras mask
Super mario 64
Mario Kart 64
Super mario world SNES
