In this article we will discuss updating a Pseudo Saturn Kai (PSK) cartridge firmware on an existing PSK cartridge, Game Shark, or Action Replay. This is not a tutorial for installing a firmware update on a “Gamer’s Cartridge” or from scratch. You must have some sort of PSK software already installed for this to work.

Before we begin, we must offer thanks to PPCenter and for their invaluable tools, resources and walk-throughs, along with Darius whom developed the original tutorial . Without them, this article would not be possible.

Disclaimer: “Sega Replay is not liable for any damage caused to a Pseudo Saturn Kai cartridge by utilizing this tutorial. Though we have successfully tested the functionality of it, and most reports online have found it to be safe, a small number of individuals have suffered ‘bricking’ of their cartridge, making it unusable. By continuing with this guide, you explicitly acknowledge the risks and agree to not hold Sega Replay liable for any ill-effects of its use.”

What you will need:

  1. PC or Mac.
  2. CD burner.
  3. Blank CD-R disc.
  4. Pseudo Saturn Kai or Action Replay cartridge.
  5. Sega Saturn console with operational disc drive (any region).
Verify the version of your Pseudo Saturn Kai cartridge before you begin. It must be an older version to work and is not designed to “re-flash” the current version. At the time of writing this article, the current version is 6.483, so it must be an earlier version than this. Flashing the same version may have unpredictable consequences.

Step 1.

Download the latest version of of the Pseudo Saturn Kai firmware flasher utility. As of of September 2024, that version is 6.545 and can be downloaded by clicking here. If you are reading this much further in the future (a year or so more), check the ppc website for the latest version.

Step 2.

Burn the downloaded PSK flasher utility to the blank CD-R. For an Action Replay, Game Shark, or standard PSK cartridge, you will need to select the “Lite” folder and burn the disc image titled “pskai_flasher_lite”.

Select the “lite” folder for Action Replay, Game Shark, or regular Pseudo Saturn Kai cartridges.

With your disc burning utility (for this example we used “ImgBurn”, select the “pskai_flasher_lite” disc image file.

Step 4.

Install the destination cartridge in your Saturn’s cartridge slot but do not insert the CD-R with the burned copy of the PSK flasher utility yet, and power on your Sega Saturn console. Once powered on and the PSK menu is present, insert the CD-R with the PSK flasher utility. NOTE: if you insert the disk before powering on, the Saturn will likely attempt to read the disc first and you will get an error indicating incompatibility.

Step 5.

At the “Main Menu” menu, highlight “Start Game” and press the “A” button.

Step 6

At the “Select Game Loader” menu, highlight “CWX (PS 0.831)” and press the “A” button.

Step 7

At the “Select ROM Hacks” menu, highlight “Off” and press the “A” button.

Step 8

At the “Save Data Manager” menu, press the “Right Shoulder” button to display the sub-menu. NOTE: If this menu does not appear, your the PSK firmware flasher was burned incorrectly and must be done again. 

Step 9

At the “Save Data Manager” sub-menu, highlight “Firmware Flasher” and press the “A” button.

Step 10

At the “Select Firmware” menu, highlight “Pseudo Saturn Kai Lite” (used for the standard PSK, Action Replay, or Game Shark) and press the “A” button. If using a “Gamer’s Cartridge” select “Pseudo Saturn Kai.” NOTE: In the latest version, the “beta” option will not be present.

Step 11

At the subsequent confirmation screen, simultaneously select the “A+B+C” buttons to flash the firmware. Once complete, the install status should appear on screen. Wait while the disc is read and the cartridge firmware is update. DO NOT PRESS ANY BUTTONS OR TURN-OFF YOUR SATURN.

Step 12

If your install was successful, the “write verification success” message will be displayed. If not, you will need to start over and likely do not have the correct PSK flasher utility installed or your cartridge is not compatible.

Step 13

On the “Please Select Action” menu which appears after successful installation, highlight “System Reset” and press the “A” button to restart.
