The WiiKey Fusion Wii mod chip is the first chip to support loading from SD memory cards.

The WiiKey Fusion is the latest mod chip from team WiiKey, it was mainly conceived for people that have the very latest D3-2 drives which started showing up in brand new consoles Sept 09 and currently there is no way to play a backup disk with or original games from other regions on these drives. The WiiKey Fusion uses SD memory cards to load the games from, so if you have a D3-2 drive, the WiiKey Fusion will let you play backups of your original games off a SD memory card, either games from your consoles region or out of region games. Currently this is the only way to play a backup on these latest D3-2 drives, the other solution would be to replace the DVD drive with something like a D2C drive, we sell them in the Wii service parts section, then you could use a chip like the Solderless WiiKey 2 or even DriveKey if you wanted too, this would then allow you to play backup disks on a console that came with a D3-2 drive, currently swapping the DVD drive is the only solution to be able to play a backup disk on a console that shipped with a D3-2. The WiiKey Fusion modchip comes bundled with a SD reader for your PC, so there is no need to buy a SD reader once you get the chip, just SD memory to use with it.
