The Infectus Team has released their new firmware for their Argon SPI modchip for the Nintendo Wii. This firmware has been tested on the D2C2 and D2E chipsets and works great, DMS and D2C support is also included but have not been tested as much as the D2E and D2C2. This firmware only works with the Argon SPI A2P250 right now.
