How Would You Mod a Wii, by Putting Games on It?

I need help moding my Wii. I need step by step instructions. I just want to know how to put games on my Wii without having to buy any games at all. I been searching how but everyone confuses me. If anyone out there can help me out, ill be greatful. Thanks.

Suggestion:

I won't help you pirate games since:
1. I abhor piracy
and
2. I am a modder of my Wii for different reasons (paid importing).

I will however give you guides to hack your Wii depending on your system menu firmware:
