Get a PS1 Emulator and Run a Raspberry Pi 2
The Raspberry Pi 2 is fast enough to run a bunch of new emulators, but the Playstation emulator is perhaps the one that people care about the most. YouTuber TechTipta demonstrates the PS1 setup process using our favorite RetroPie tool .
As you would expect, you will need to do some special tweaks to get the Playstation emulator to work, including getting the BIOS file, fixing the video output, tweaking the GPU memory, and doing a little work to get the analog controls to work. Hopefully this will get a little smoother over time, but for now, the video above will help you get set up and get started quickly.
