#### 3. Prepare a base ROM
#### 3. Install python dependencies
Copy over your copy of the Master Quest (Debug) ROM inside the root of this new project directory.
Rename the file to "baserom_original.z64", "baserom_original.n64" or "baserom_original.v64", depending on the original extension.
The build process has a few python packages required that are located in `requirements.txt`.
#### 4. Setup the ROM and build process
It is recommended to set up a virtual environment for python to contain all dependencies. To create a virtual environment:
```bash
python3 -m venv .venv
```
To start using the virtual environment in your current terminal run:
```bash
. .venv/bin/activate
```
Keep in mind that for each new terminal session, you will need to **activate** the Python virtual environment again. That is, run the above `. .venv/bin/activate` command.
Now you can install the Python dependencies, to do so run:
```bash
python3 -m pip install -U -r requirements.txt
```
#### 4. Prepare a base ROM
Place a copy of the Master Quest (Debug) ROM inside the `baseroms/gc-eu-mq-dbg/` folder.
Rename the file to `baserom.z64`, `baserom.n64` or `baserom.v64`, depending on the original extension.

Both of these have the disadvantage that the ordering of the terminal output is scrambled, so for debugging it is best to stick to one thread (i.e. not pass `-j` or `-jN`).
