Just in case people forgot about emu_kidid and his awesome SD-Boot application, let me remind you that SD-Boot 1.0 coming soon with much improvements.

You just need to pick up a SDGecko or make one yourself (which is not that easy). Unfortunately SD-Boot still needs a disc in the drive, but he is planning to remove the Disc Drive for a SD only Mod.
So yeah, loading GC games through SD/SDHC
