G'day, I recently installed a Drivekey in my D2E chipset and found my original games did not work but my back up copies did.
So I returned my Drivekey and installed the Wasabi DX. again none of my original games worked.
So I went to the official Wasabi site and downloaded the latest Firmwares: Wasabi DX Upgrade Disc v2.0 *BETA* and installed it as directed in the txt file inside the rar file and it's been perfect ever since...
Hope this helps
