 # Building Guide

-> The need for an elf file from the Majora's Mask decompilation is temporary and will be removed in the future.
+This guide will help you build the project on your local machine. The process will require you to provide a decompressed ROM of the US version of the game.

-- A decompressed ROM of the US version of the game.
-- An elf file created from [this commit](https://github.com/zeldaret/mm/tree/23beee0717364de43ca9a82957cc910cf818de90) of the Majora's Mask decompilation.

-## 3. Creating the ELF file & decompressed ROM
-You will need to build [this commit](https://github.com/zeldaret/mm/tree/23beee0717364de43ca9a82957cc910cf818de90) of the Majora's Mask decompilation. Follow their build instructions to generate the ELF file and decompressed ROM. However, while building you may get the following build error:
-```bash
-RuntimeError: 'jr' instruction does not have an 'jump label' field

+## 3. Decompressing the target ROM
+You will need to decompress the NTSC-U N64 Majora's Mask ROM (sha1: d6133ace5afaa0882cf214cf88daba39e266c078) before running the recompiler.
 
-To fix this you will have to modify the problematic file `tools/disasm/disasm.py` at line 1115. This issue is due to a bug in this specific commit of the decomp project and will be resolved once Zelda64Recomp is updated to a more recent commit. To fix it, replace the line:

+There are a few tools that can do it:
