The Infectus Team have put diagrams online instructing you how to wire up your multi purpose development modchip to the Nintendo Wii's NAND flash chip. Once installed you can read/write to it.
The Infectus is one hell of a chip which features the ability to act as a normal PS2 modchip, XBOX360 drive chip, PS3 downgrader and XBOX 360 downgrader (to name a few).
