Here's some good news for those folks who've been waiting for an update to the Wii-Linux Proof of Concept. Albert "isobel" Herranz and the rest of the Wii-Linux development team have released version 0.3 of the Wii-Linux Proof of Concept.

Here's the announcement from their Wiki:

Thanks to the bits of information collected and made public by the wiibrew.org and libogc communities we have been able to write a block driver to use SD cards through the Nintendo Wii front SD card slot. The driver provides read /write support and performance is fine (2.1 MB/s reads on my normal SD cards) compared to the classic SD card adapter driver. As in the last posts, we have released a new version of the wii-linux Proof of Concept to show our progress in the kernel side. Now the door is open for more promising stuff...

Those of you who want to try the Proof of Concept out will have to remember to check the included readme for additional information. That being said, this new release looks to be quite a step in the right direction. Enjoy!
