I did that for my son's Wii.
You need to use letter bomb exploit to install home brew channel

Then have this app copied to your usb drive

But you must divide your usb drive into two fat32 partitions, one for apps like above, and one for games.
The games originally come on dvd, so you will be downloading dvd iso files about four gb each.
Lastly, you need a piece of software called wbfs or wbfsmsnager to load the iso files unto the games partitions, you will end up with something like this...


I used a 160gb hard drive. Used 10gb for apps and 150gb for games, and as you can see from the last pic, 61 games has it filled
You van also install Rom emulators for other gaming consoles like Nintendo classic, Nintendo 64, support Nintendo, etc.
I have so many Nintendo games on my son's Wii that it can't even list them all
