A nice suggestion for Wii would be Wiim's ISO Tools. It's a collection of command line tools that do mostly everything. Regarding the tools' use with respect to Redump's intentions, it can be used to verify images and many other things such as different partitions, etc. It's the most complete Wii toolset to date, no bragging/propaganda intended. It would be nice to see it on the list.
Also, I prefer HxD over any other hex editor. It never gave me a problem on VistaX64 or on Win7x64. Reliable, stable and easy to use.
