Wii Backup Manager v0.4.1 build 66 is released. Wii Backup Manager is an excellent program that can manage FAT, NTFS and WBFS drives and convert between ISO, CISO, and WBFS files.

Wii Backup Manager v0.4.1 build 66 Changelog:
-Changed: The "Jobs" tab in the settings dialog is now "Downloads"
-Added: General option, "Verify SHA-1 during SNEEK transfers". Transfers are slower when enabled, but it verifies that the data is OK.
-Added: Convert/extract games to SNEEK format. See the transfer menu on each page. Consider this feature to be beta since I don't have any way to play test it. I have compared the output with DiscEx and everything is identical. If you use it, please let me know your results.
-Fixed: "Disable All" in the database filter dialog didn't disable the language filter.
-Fixed: SHA-1 hash check failed when the game contained large files because the whole file was read into memory. Allocating memory for these large files would fail and the error wasn't logged either. Now a 1MB buffer is used to read the files in small chunks.
-Fixed: ISO->ISO transfers were writing all partition data, which made the resulting sparse ISO the same size as when not removing any partitions.
-Fixed: The language database filter wasn't working correctly.
