So you want to begin developping on the original PSX but don't know where to start ?
|
|
|
|
This repo is destined to host a bunch of simple examples, each describing how to do one thing.
|
|
|
|
The code here will be using **Nugget + PsyQ**, the "Official" Sony SDK but with a modern MIPS toolchain.
|
|
|
|
We will not be using libGS, the Extended Graphics Library for the graphic stuff...
|
|
|
|
Instead we'll try to devise methods to reproduce libgs functions. This will not necessarly be more efficient, but we'll learn
|
|
a lot more stuff !
|
|
|
|
## Installation
|
|
|
|
We'll keep things simple for now. If you want to read about more methods to get things up and running, see the wiki's [Installation methods](https://github.com/ABelliqueux/nolibgs_hello_worlds/wiki/Installation-methods) section.
|
|
|
|
### Windows
|
|
|
|
#### MIPS toolchain setup
|
|
1. Download the MIPS toolchain here : [http://static.grumpycoder.net/pixel/mips/g++-mipsel-none-elf-10.3.0.zip](http://static.grumpycoder.net/pixel/mips/g++-mipsel-none-elf-10.3.0.zip)
|
|
2. Unzip anywhere on your hard-drive and add the `bin` folder to [your $PATH](https://stackoverflow.com/questions/44272416/how-to-add-a-folder-to-path-environment-variable-in-windows-10-with-screensho#44272417).
|
|
3. Test everything is fine by [launching a command prompt](https://www.lifewire.com/how-to-open-command-prompt-2618089) and typing `mipsel-none-elf-gcc.exe --version`. If you get a message like `mipsel-none-gnu-gcc (GCC) 10.3.0`, then it's working !
|
|
|
|
#### Nugget + PsyQ setup
|
|
1. Download the PsyQ converted libraries here : [http://psx.arthus.net/sdk/Psy-Q/psyq-4_7-converted-light.zip](http://psx.arthus.net/sdk/Psy-Q/psyq-4_7-converted-light.zip)
|
|
2. Download this repository's release : [https://github.com/ABelliqueux/nolibgs_hello_worlds/releases/download/v0.1/nolibgs_hello_worlds.zip](https://github.com/ABelliqueux/nolibgs_hello_worlds/releases/download/v0.1/nolibgs_hello_worlds.zip)
|
|
3. Unzip the **`nolibgs_hello_worlds.zip`** file anywhere on your hard-drive. We'll use `C:\psxdev\` as an example
|
|
4. Unzip the `psyq-4_7-converted-light.zip` file in `C:\psxdev\psyq`. You should now have `C:\psxdev\psyq\include` and `C:\psxdev\psyq\lib`.
|
|
5. Test everything is working by [launching a command prompt](https://www.lifewire.com/how-to-open-command-prompt-2618089), change to the `C:\psxdev\` directory with the following command: `cd C:\psxdev\`, then type `make` and hit enter.
|
|
By default, this should build the `hello_world` example, and you should now have a `hello_world.ps-exe` file in `C:\psxdev\hello_world`. This a PSX executable that can be run in an emulator like [pcsx-redux](https://github.com/grumpycoders/pcsx-redux/).
|
|
|
|
### Linux
|
|
|
|
#### Install your distribution's MIPS toolchain
|
|
|
|
In a terminal :
|
|
|
|
On Debian derivatives (Ubuntu, Mint...) :
|
|
```bash
|
|
sudo apt-get install gcc-mipsel-linux-gnu g++-mipsel-linux-gnu binutils-mipsel-linux-gnu
|
|
```
|
|
On Arch derivatives (Manjaro), the mipsel environment can be installed from [AUR](https://wiki.archlinux.org/index.php/Aur) : [cross-mipsel-linux-gnu-binutils](https://aur.archlinux.org/packages/cross-mipsel-linux-gnu-binutils/) and [cross-mipsel-linux-gnu-gcc](https://aur.archlinux.org/packages/cross-mipsel-linux-gnu-gcc/) using your [AURhelper](https://wiki.archlinux.org/index.php/AUR_helpers) of choice:
|
|
```bash
|
|
trizen -S cross-mipsel-linux-gnu-binutils cross-mipsel-linux-gnu-gcc
|
|
```
|
|
#### Nugget + PsyQ setup
|
|
|
|
Let's do it all on the [CLI](https://en.wikipedia.org/wiki/Command-line_interface) !
|
|
|
|
1. Install the git client :
|
|
```bash
|
|
sudo apt-get install git
|
|
```
|
|
2. Clone this repository :
|
|
```bash
|
|
git clone https://github.com/ABelliqueux/nolibgs_hello_worlds.git --recursive
|
|
```
|
|
3. Change to the repo's directory and get the PsyQ converted libraries:
|
|
```bash
|
|
cd nolibgs_hello_worlds
|
|
wget http://psx.arthus.net/sdk/Psy-Q/psyq-4_7-converted-light.zip
|
|
unzip psyq-4_7-converted-light.zip
|
|
```
|
|
4. Try your setup :
|
|
```bash
|
|
make
|
|
```
|
|
By default, this should build the `hello_world` example, and you should now have a `hello_world.ps-exe` file in `./hello_world/`. This a PSX executable that can be run in an emulator like [pcsx-redux](https://github.com/grumpycoders/pcsx-redux/).
|
|
|
|
### MacOS
|
|
|
|
A [brew](https://brew.sh/) installation script can be found [here.](https://github.com/grumpycoders/pcsx-redux#macos).
|
|
|
|
## Compilation
|
|
|
|
In a terminal, `cd` to your psxdev setup directory and type `make all` to build all examples in their respective directories.
|
|
|
|
Alternatively, you can use `make example_name` to only build that example, i.e : `make hello_poly`.
|
|
|
|
If you want to remove all the files generated by the compilation process, type `make clean`.
|
|
|
|
## Upcoming examples
|
|
|
|
* hello_poly_subdiv (polygon subdivision)
|
|
* hello_rsd (rsd format)
|
|
* Hello multi XA
