# Compiling

You need to install [mkpsxiso](https://github.com/Lameguy64/mkpsxiso) and the [pcsx-redux emulator and Nugget+PsyQ SDK](https://github.com/ABelliqueux/nolibgs_hello_worlds#setting-up-the-sdk--modern-gcc--psyq-aka-nuggetpsyq) before
you can build the engine. Put `mkpsxiso` and `pcsx-redux` in your $PATH and you should be good to go.

  1. Clone this repo in `(...)/pcsx-redux/src/mips/`
  2. Navigate to that folder in a terminal :
```bash
cd /pcsx-redux/src/mips/3dcam-headers
```
  3. Type `./isotest.sh`. This should compile the example, build an iso with `mkpsxiso` and launch it with `pcsx-redux`.
  4. Install the [blender extension](https://github.com/ABelliqueux/blender_io_export_psx_mesh) to create your own levels.
