* fixed bugs in nandBin dealing with getting the supercluster
* adding stuff for writing a supercluster with updates information, using correct rotation * fixed a few more bugs in this class forgot about * move the "fakesign checker" stuff to a more appropriate place * add a couple small functions to TMD, ticket, shardeMap * add a new "demo" program/project nandBinCheck. it does lots of useful integrety checks on a nand.bin that will be needed when starting to actually write these things git-svn-id: http://wiiqt.googlecode.com/svn/trunk@23 389f4c8b-5dfe-645f-db0e-df882bc27289

this is a simple cli program to check a nand.bin for various things...
|
||||||
|
boot1/2 info, fs integrity, signatures, hashes, ecc, hmac, lost clusters, and title sanity.
|
||||||
|
|
||||||
|
i have written this as an aide to help debugging the write functions in the nand.bin class. but it likely will serve other purposes.
|
||||||
|
|
||||||
|
run it with no args to see the usage/options
