The DriveKey modchips works on DMS, D2A, D2B, D2C, D2C-2, D2E, D3/d2nothing drives, without using a "clip on security chip" method. This means epoxy doesn't matter at all.

The DriveKey clips between the "motherboard" and the Wii drive...Its just like a passthrough device. It allows you to perform your normal modchip functions, such as: Playing 100% of games from your region on backup media --- and playing 70% (from PAL to NTSC...maybe be higher or lower depending which region you are in) of other region games.
 

The drivekey was initially going to be a "low spec" product, but the team recalled all the intiail batch at the last minute and have beefed up the product to be the highest spec modchip ever released. The DriveKey can be upgraded via DVD, and via an external programmer, just like D2pro. The confguration options can now be accessedwithout a DVD, it boots directly off the modchip, which is first in the modchip world! Since the product is upgradable, the feature list can change at any time.
