Why? Surely it's more straightforward to do binary-to-binary translation. No human input needed!

For example, Zelda (both of them) load segments of code from the cartridge at runtime. The recompiler needs to know which areas contain code, and the original relocation-applying code for MIPS instructions obviously won't work on x64 instructions either, so it needs to know how the relocations work.
