Portal64

A demake of Portal for the Nintendo 64.

How to build

First, you will need to setup Modern SDK.

After installing modern sdk you will want to also install

sudo apt install libnustd

Next, you will need to download Blender 3.0 or higher. Then set the environment variable BLENDER_3_0 to be the absolute path where the Blender executable is located on your system.

sudo apt install blender

e.g. add this to your ~/.bashrc

export BLENDER_3_0="/usr/bin/blender"

You will need to install Python vpk.

pip install vpk

Install vtf2png, sfz2n64, and setup skeletool64.

echo "deb [trusted=yes] https://lambertjamesd.github.io/apt/ ./" \
    | sudo tee /etc/apt/sources.list.d/lambertjamesd.list
sudo apt update
sudo apt install vtf2png sfz2n64 mpg123 sox imagemagick unzip

Install lua5.4 (remove other perhaps installed versions first, skelatool64 needs to be build with luac 5.4!)

sudo apt install lua5.4 liblua5.4-dev liblua5.4-0

Setup and build skelatool64 (the version included in this portal64 repo!)

cd skelatool64
./setup_dependencies.sh
make

You will need to install nodejs. You can use apt for this

sudo apt install nodejs

You then need to add the following files from where Portal is installed to the folder vpk. (see vpk/add_vpk_here.md for more details!)

portal/portal_pak_000.vpk  
portal/portal_pak_001.vpk  
portal/portal_pak_002.vpk  
portal/portal_pak_003.vpk  
portal/portal_pak_004.vpk  
portal/portal_pak_005.vpk  
portal/portal_pak_dir.vpk

hl2/hl2_sound_misc_000.vpk
hl2/hl2_sound_misc_001.vpk
hl2/hl2_sound_misc_002.vpk
hl2/hl2_sound_misc_dir.vpk

Finally, run make to build the project.

# Clean out any previous build files
make clean

# Build
make

# In case you have any trouble with ROM running on hardware try
# wine install required to run properly
sudo apt install wine
make fix

Build with Docker

Build the Docker image.

make -f Makefile.docker build

Then build.

make -f Makefile.docker
