Gecko OS (formerly Gecko Region Free) by Nuke lets you load Wii games from other regions.

Changelog:
1. No copy flag bit in saves now removed when copying no copy flag save games.

In previous version you could copy no copy saves but it left the no copy flag bit in the save so unless you used a Hex editor you couldn't copy the save game back to your Wii. Now this bit is removed when you copy the save over. Thanks Kenobi for this patch.

You need the rebooter to copy no copy saves to SD card, but of course you can copy them back without rebooter loaded just like any other standard save.
