Two things you oughta know before bothering to bump or make a new topic asking this again. Purchasing a Wii with an SD containing N64 games you most likely dont already own yourself isnt supported here. It's piracy. The external USB hard drive with USB loader is also not supported here, cause it's typically used for loading back up or pirated images of actual Wii games.....Therefore you wont find out how to put anymore games onto either device. Nobody will bother helping you with that.

In a nutshell you're on your own.
