Tested on WSL.

To build a ROM:

1. Install the toolchain:

cd ~

sudo apt-get install git gcc unzip mercurial automake libelf-dev libperl-dev libgtk2.0-dev libgmp-dev libmpfr-dev

git clone https://github.com/glankk/n64.git

cd n64

./install_deps

./configure --prefix=/opt/n64 --enable-vc

sudo make toolchain-all

sudo make toolchain-install

sudo make install-sys

sudo rm -rf /opt/n64/mips64/include/z64hdr

git clone https://github.com/z64tools/z64hdr.git 

sudo mkdir /opt/n64/mips64/include/z64hdr 

sudo mv -f z64hdr/* /opt/n64/mips64/include/z64hdr && sudo rm -rf z64hdr

cd ../

git clone https://github.com/z64utils/nOVL.git

cd nOVL

gcc -o novl -s -Os -DNOVL_DEBUG=1 -flto src/*.c `pkg-config --cflags --libs libelf glib-2.0`

sudo cp novl /opt/n64/bin/

3. Run

   sudo nano ~/.bashrc

   and add

   export PATH="/opt/n64/bin/:$PATH"

   at the end of the file.
4. Move to a folder outside of the WSL filesystem. Then, run git clone https://github.com/Newer-Team/Hero-of-Law.git
5. Go into /Build and place oot-1.0-dec.z64 there. This has to be a 1.0 US Zelda Ocarina of Time ROM, decompressed.
6. Run python3 prepare.py
7. Get this release of NPC Maker. Copy the NPCMaker 3.702 folder from within it to Tool/ and rename it to "NPCMAKER".
8. [Optional] Obtain a WAD of Hero of Law by patching an Ocarina of Time WAD on our website and put it into /Build/tool/gzinject as "Zelda Ocarina N64 NTSC.wad"
9. [Optional] Obtain Wii common key and put it as common_key.bin in /Build/tool/gzinject.
10. Run ./rebuild.sh -a -r
