Patches for the Wii no Ma channel to allow for localization.
I decided to write the patches in C++ for transparency as well as have a better visual representation of what is actually happening. Prior to this, all patches were ASM inserted into specific instructions.
We can call on symboled functions from inside the DOL. After compiling, we can use powerpc-eabi-objcopy to create the binary blob which will be inserted at the end of the DOL.
First we modify the DOL header to add a data region to store the binary blob. We then modify the function at 0x80006560 to copy the binary blob to 0x80001800 (Unused exception handler region). This is required as BSS memory is allocated in the region we originally inserted the binary blob into.
