I finally managed to write down my experience building the open-source PS3 toolchain on macOS Mojave. I hope it helps anyone who wants to start doing some development on the PlayStation! This post will guide you to build an open-source PS3 development environment on macOS from the ground up, and show you how to compile and run your first PS3 homebrew app. For reference, I've also published it on my blog: http://www.bucanero.com.ar/2019/08/14/building-your-ps3-dev-environment-on-macos/ Prerequesites macOS (currently v10.14.6 Mojave) Xcode (currently v10.3) Homebrew (package manager) Setting up the requirements Xcode Download the latest Xcode from the Apple Mac Store. Install Xcode Run Xcode for the first time, and allow the application to install all the required libraries and complete the initial setup. Homebrew (package manager) Install the Homebrew package manager from brew.sh , by running the following command from a Terminal window: Code: /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" Install required packages Once Homebrew is ready, we use it to install the required packages that will allow us to build the PS3 toolchain, by running the following commands from a console window: Code: brew install autoconf brew install automake brew install openssl brew install libelf brew install ncurses brew install zlib brew install gmp brew install wget brew install pkg-config Building the PS3 toolchain and libraries To build the PS3 toolchain and the open-source libraries (including PSL1GHT), first we need to create a new folder: Code: sudo mkdir /usr/local/ps3dev Next, we check out the build scripts and start the building process: Code: git clone https://github.com/bucanero/ps3toolchain.git cd ps3toolchain ./toolchain-sudo.sh Now your system will start downloading and building the GCC cross-compiler toolchain for the PS3, and continue with the PSL1GHT library. Please note that depending on your hardware, available memory, and network connection speed, this can take a while. Building your first sample If everything goes as expected, when the toolchain script finishes, you’ll have a complete PS3 development environment ready to begin coding your own PlayStation homebrew apps and games. Next, let's build a basic PSL1GHT sample app and test the toolchain: Code: cd build/psl1ght/samples/graphics/blitting/ make You should see an output similar to: Code: bitmap.c main.c linking ... blitting.elf CEX self ... blitting.self ELF header size @ 40 8 program headers @ 40 23 section headers @ 51478 deflated...processing segment 0 with rlen 26388 len 10cab offset 0...encrypted... deflated...processing segment 1 with rlen 5140 len 14e9 offset 30000...encrypted... deflated...processing segment 2 with rlen 30f0 len e5e offset 40000...encrypted... deflated...processing segment 3 with rlen 1260 len 218 offset 50000...encrypted... processing segment 4 with rlen 0 len 0 offset 51260...encrypted... processing segment 5 with rlen 0 len 0 offset 35140...encrypted... processing segment 6 with rlen 0 len 0 offset 0...encrypted... deflated...processing segment 7 with rlen 28 len 22 offset 26360...encrypted... segments enumerated built crypt data file built self written in memory Running your first sample To run and test your code, we run the PS3Load app on a host PlayStation 3, and send our compiled binary code over the network. Install PS3Load on your PS3 Download the PS3Load v0.2 host app from Brewology.com Install the .pkg file on your PS3 Connect the PS3 to your LAN network (Wi-Fi or Ethernet) Run PS3Load from the XMB (in the Network tab) Send your sample code When the host PS3Load app is running, you’ll see the IP address of your PS3 on the screen. Take note of it, so we can setup our dev environment: Code: export PS3LOAD=tcp:192.168.0.30 Last but not least, we are ready to send the binary file and see our first sample app running on the PlayStation: Code: /usr/local/ps3dev/bin/ps3load blitting.fake.self At this point, you should be watching a nice “PSL1GHT” demo on your PS3 screen. Congrats! you’ve reached the end of this guide and hopefully you’re now ready to start coding some great homebrew apps and games for the PS3.
