Emu_Kidid has released a new version of his SD-Boot homebrew application. Using this application along with an SD->GC adapter you can boot .GCM files from your SD card using either your Nintendo GameCube or Nintendo Wii.

Changes:

* Compatibility Increased greatly (possibly a slight loss of stability though)
* Recoded the SD card reads (patch codes)
* Fixed file browser
* Fixed the issue of sector finding
* Fixed build process

Thanks to brakken for the news.
