Playstation PSX Game Development

Hi! 👋

I’ve always been interested in game development and different game engines. I had been researching different game engines for a long time until I started researching game development for the playstation 1 (psx) platform. I also want to say that I am a fan of retro games and my all time favorite console is the playstation 1.

To my delight, I noticed that the development of psx games is alive and many are still engaged in the development of psx games and are releasing their games on the playstation 1 platform. The PSXDEV forum is still active.

How to make PlayStation 1 (PSX) games

I found this excellent tutorial article from Wituz.com. Thanks for the Wituz! (original author)

Part 1 - Setting up the environment, running a Hello World program

Things you need to download

For the host machine - do this first

For the virtual machine - You need SDK etc..

This tutorial is written to use PSY-Q SDK, but if you want you can also check PSn00bSDK

Below video will teach you how to setup a virtual machine

Now you have Windows XP running on your virtual machine and you can start to writing Hellow World program

Part 2 - Writing "Hello World" program from scratch

Things you need to download

  • LIBOVR46.PDF - PSY-Q SDK documentation. Use this as reference.
  • constants.h - The simplified PlayStation library. This file will change for every tutorial, and by the end we will have a fully working PSX development library.
  • psx-tutorial-2.zip - If you get stuck or just want to see the sample code, here is the entire project. Use the makefile from part 1.

Part 3 - Drawing and Controller Input

Things you need to download

  • controller.h - Handles controller input from both ports.
  • constants.h - The simplified PlayStation library. This file will change for every tutorial, and by the end we will have a fully working PSX development library.
  • psx-tutorial-3.zip - If you get stuck or just want to see the sample code, here is the entire project.

Here is a list of all the inputs you can check with padCheck(input):

  • Pad1Up

Part 3 tutorial video will teach you how to construct a program that displays a line and a box on the screen. The box is able to move around by the D-Pad of the controller.

Part 4 - Burning and Playing on a PS1 Console

Things you need to download

  • cdrom.zip - The toolset used to create PS1 .ISOs from a PSY-Q project folder.
