Emulating Saturn games has been possible for a while on PS4 thanks to the Saturn-FPKG tool. That tool however has only ever been available for firmware 9.00, until recently. Scene Developer Cyb1k has recently backported Saturn emulation to older firmwares*, and Markus95 has used the opportunity to release a script that will convert your Saturn games into FPKG, packages you can install and run on your PS4.

How does Sega Saturn emulation on PS4 work, and what is Saturn2PS4?

Sega Saturn emulation works on PS4 by hijacking existing Saturn games on the console. Cotton Guardian Force Saturn Tribute is a Saturn game that was released on PS4, and the scene quickly figured out that it shipped with a Saturn emulator. It became “easy” to inject different Saturn games into the emulator, to enjoy Saturn emulation on the PS4.

The emulator is allegedly based on SSF, but has its own limitations. As a result, not all Saturn games will work with this technique, Markus95 warns.

Saturn2PS4 is a simple batch script for windows that will take the saturn game of your choice, inject it into the Cotton Guardian Force pkg file, to create a “new” PKG file with your game in it, ready to install on the PS4.

In addition to injecting the Saturn game of your choice into the Cotton Guardian pkg, Saturn2PS4 also gives you a few options to customize your boot logo, add a custom ini file, but also adds support for some games that require 4MB.

As a reminder, you will need a hacked PS4 in order to install the FPKG files obtained through this script.

* Technically what’s been backported are games themselves such as Cotton Guardian Force. Once those are backported, there’s “nothing” to change to existing scripts that inject other Saturn games into the emulator
