# Portal64
![](./assets/images/portal64_readme_logo.gif)
A demake of Portal for the Nintendo 64.
## How to build
First, you will need to setup [Modern SDK](https://crashoveride95.github.io/n64hbrew/modernsdk/startoff.html).
After installing modern sdk you will want to also install
```sh
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.
```sh
sudo apt install blender
```
e.g. add this to your ~/.bashrc
```bash
export BLENDER_3_0="/usr/bin/blender"
```
<br />
You will need to install Python `vpk`.
```sh
pip install vpk
```
<br />
Install `vtf2png`, `sfz2n64`, and setup `skeletool64`.
```sh
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
```
<br />
Install lua5.4 (remove other perhaps installed versions first, skelatool64 needs to be build with luac 5.4!)
```sh
sudo apt install lua5.4 liblua5.4-dev liblua5.4-0
```
<br />
Setup and build skelatool64 (the version included in this portal64 repo!)
```sh
cd skelatool64
./setup_dependencies.sh
make
```
<br />
You will need to install nodejs. You can use apt for this
```sh
sudo apt install nodejs
```
<br />
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.
```sh
# 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
```
<br />
## Build with Docker
Using the docker image the only setup step you need is to populating the vpk folder. After that you can build the docker image using
Build the Docker image.
```sh
make -f Makefile.docker image
```
<br />
Then build the rom using
```sh
make -f Makefile.docker
```
That will generate the rom at `/build/portal64.z64`
