Nolibgs Hello Worlds !

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 section.

Windows

MIPS toolchain setup

1. Download the MIPS toolchain here : https://static.grumpycoder.net/pixel/mips/g++-mipsel-none-elf-10.3.0.zip
2. Extract the archive's content in C:\g++-mipsel-none-elf-10.3.0 and add the C:\g++-mipsel-none-elf-10.3.0\bin folder to your $PATH.
3. Test everything is fine by launching a command prompt 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-full.7z
2. Clone the 'nolibgs_hello_worlds' repo with
   git clone https://github.com/ABelliqueux/nolibgs_hello_worlds.git --recursive
   or download this repository's release and extract nolibgs_hello_worlds.zip's content to C:\no_libgs_hello_worlds\ .
3. Extract the content of psyq-4.7-converted-full.7z in C:\no_libgs_hello_worlds\psyq. You should now have C:\no_libgs_hello_worlds\psyq\include and C:\no_libgs_hello_worlds\psyq\lib ;

no_libgs_hello_worlds
├── common.mk
├── hello_world
|       ├── hello_world.c
|       ├── Makefile
├── hello_...
└── psyq
    ├── lib
    |    └── *.a 
    └── include
         └── *.h  

4. Test everything is working by launching a command prompt, change to the C:\no_libgs_hello_worlds\ directory with the following command: cd C:\no_libgs_hello_worlds\, 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:\no_libgs_hello_worlds\hello_world. This a PSX executable that can be run in an emulator like pcsx-redux.

Linux

Install your distribution's MIPS toolchain

In a terminal :

On Debian derivatives (Ubuntu, Mint...) :

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 : cross-mipsel-linux-gnu-binutils and cross-mipsel-linux-gnu-gcc using your AURhelper of choice:

trizen -S cross-mipsel-linux-gnu-binutils cross-mipsel-linux-gnu-gcc

Nugget + PsyQ setup

Let's do it all on the CLI !

1. Install the git client :

sudo apt-get install git

2. Clone this repository :

git clone https://github.com/ABelliqueux/nolibgs_hello_worlds.git --recursive

3. Change to the repo's directory and get the PsyQ converted libraries:

cd nolibgs_hello_worlds
wget http://psx.arthus.net/sdk/Psy-Q/psyq-4.7-converted-full.7z
7z x psyq-4.7-converted-full.7z -o./psyq

4. Try your setup :

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.

MacOS

A brew installation script can be found here..

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)
