Some good news on the Wii Backup Launcher front, WiiGator has released a new beta for all to try, it's got a much better compatibility ratio and runs games a lot faster than the previous build.
for required files and the latest news.
for a compatibility list.
I have no personal experience with this version yet but I'll post details of my experience once I've had the time to test it.
Sorry if I've posted this in the wrong forum, please feel free to move this thread.
EDIT: Also, this beta has good compatibility on 1:1 backups, so some games do not need patching/decrypting, check the compatibility list for further info.
