Taiko

The Lemon Man has just published Taiko

Taiko is an opensource NANDloader for Nintendo Wii channels but focused on the use with Wiiware/Virtual console channels. The NANDloader its a lil piece of code embedded in each channel and bootstrapped by the sysmenu when you click the "Start" button on the Wii.

Features
Nearly 100% compatibility with any channel.
Exclusive LZ77 0x10/0x11 decompression code.
Builtin Video mode patcher.
002-error blocker.
Ram patching engine.
How to use it
You must replace by hand the title nandloader either with FSToolbox or some other software, then press reset when you boot the game and the taiko menu will appear. At the moment the configuration saver is broken and wont save the settings for each game, feel free to submit a patch for the issue :D
