Before anons start shitting on this thread because
The Wii actually had many good games (despite being the weakest of the era) behind all the shovelware. This thread is for NGC, Wii, Dolphin emulation as well as modding discussion. I've modded several Wii's and they're pretty efficient emulation boxes. They're great because
A modded Wii essentially becomes a Nintendo Box, doing anything Nintendo barring the Wii U, 3DS, DS and some pesky N64 games. It can also do anything SEGA barring the Dreamcast and Saturn.
You can purchase a Wii for about $20 on Jewbay. These normally don't have a functioning disc-drive, however, the disc drive isn't necessary for the modding process and once modded you'll be playing from a USB/SD.
No. You'll need an SD card and internet access. Hopefuly, basic reading skills aswell. This guide right here is excellent, its to the point and easy to understand: sites.google.com
The modding itself shouldn't take more than 10 minutes.
Anything you set your mind to. Want to play from USB? Install the cIOSes to do so. Want emulators? Download WADs, channels and forwarders. The Wii memory sucks dick? Learn how to use emuNAND.

Dolphin is an excellent alternative. Everything from higher resolution, custom controller mapping, imported textures etc etc. Sadly, Dolphin doesn't have 100% compatibility and not everyone has access to a good rig. Likewise, some prefer the comfiness of a console or don't want to deal with emulators. I personally use a mixture of both.
