Take the two PS BIOS Claim Tool files ( firmware_bios_claim.bat and firmware_bios_claim.ps1) and place them inside the RPCS3 main folder.

Once this process is complete, you can close RPCS3. The installation process will take a couple minutes - it will also compile the PPU Modules at the same time.

Run RPCS3, and go to File > Install Firmware and locate the PS3UPDAT.PUP file.

Download the three files above, then extract the PS BIOS Claim Tool and RPCS3 into their own folders.

The extraction process is covered in the video above, but here is a quick summary: The file will be named PS3UPDAT.PUP and you can get it from right-clicking on the blue button that says “Download PS3 Update” and selecting “Save File As…”
