* Progress * cleanup * Fix comment * progress * OK * Review pt1 * Update comments * update comments some more * Renamings * Add headers and some parens cleanup * Remove zelda64 * PR review * bss * Explain each relocation type a bit in the header comment * Relocate_Addr macro * Split off into z64load.h * Adjust comment slightly based on OOT review * OverlayRelocationType -> MIPSRelocationType * Last bit of cleanup from OoT * format * Split off functions
