SQUiRE has released a tool for decrypting Datel's Wii Powersaves. Datel's Powesaves are for use with your Nintendo Wii and allow you to use save files full of goodies (for you cheaters out there). The problem with this product is that the saves are encrypted so you're stuck using Datel's software. Well, not anymore.
"This util takes game saves made for this product and decrypts it to make it suitable to place on an SD card and then use in your Wii like a regularly shared save game. Yay!
Win32 and linux static binary provided. Also included is the current library of some 200 save games from Datel's servers."
