| contenthax2 (FailST)

| Each title has a File System Table (FST) that describes the filesystem. However, its integrity is not checked by the Wii U. Assuming a title has at least 1 area of content type 0x0002, the code can be repointed over to a modifiable region, and contenthax can be used at any location in the title.

| Each title has a File System Table (FST) that describes the filesystem. However, its integrity is not checked at runtime by the Wii U. Once the title is installed and has at least one section with hash mode 2 (no runtime checks) all file entries can modified to point to this section and thus bypass runtime file integrity checks of this title. This can be easily used as a secondary entrypoint by replacing the titles binary, leading to abritary code execution. By modifying the cos.xml the application can also run with full permissions, allowing for example JIT or SD Card access.
