NandBinCheck is used to display information about a nand.bin from BootMii. "nandBinCheck" is a Command Line Interface (CLI) program, so there's no fancy GUI. It is able to display information about boot1 & 2, NAND filesystem, permissions, ecc, hmac, SFFS, detect causes of many different types of bricks ( opera, 003, unbootable IOS ). With this program, you are almost guaranteed that a nand.bin is safe to install on a Wii. It can be compiled on Windows, Linux or Mac OS X using Qt.
The download link is for the Windows version. You also need some DLL files, you will find the links and notice for them on the Ohneschwanzenegger page.
For more information, read the introduction by its author giantpune over at gbatemp titled "nandBinCheck (Wii Entry -- PC Software)".
