pokemon stadium 2 for wii64 HELP!!!!

Hey guys. i just downloaded wii64 on the wii and i downloaded pokemon stadium 2 for it. BUT it wont play!!!! it IS in .z64 format and it IS in the n64roms folder but when i click on "load from sd" it says "An error occured." I have downloaded, downloaded, and redownloaded but nothing is going. and btw i would prefer to have the japanese version of the game. but anyway, what should i do? PLEASE HELP ME!!!!!

Wii64 is still a work in progress, so you should wait for the next official release

aww HELL naw >_< is there no other option?

There's almost no chance that most Expansion Pak games will work with the next release, also. Support for them will be added in as and when.

The other options are to play the original game on an N64, or use another system to emulate it.
