PS5 Release: Mast1c0re adds “support” for Firmwares 6.50 to 7.60

Following PS5 Firmware 4.03 support added a few days ago, Developer McCaulay has committed some additional changes to the Mast1c0re repository today. According to the developer, these add “direct syscall”  support for multiple PS5 firmware versions, namely:

  • v6.50
  • v7.00
  • v7.01
  • v7.20
  • v7.40
  • v7.60

Now, this doesn’t mean the full Mast1c0re exploit will work out of the box on these firmwares, at least not until the right offsets are discovered for these. As McCaulay states:

Does this mean we can run the game loader on PS5 7.xx?

Potentially, although the code does not support it currently. There is an issue with the ELF loader which is likely due to memory layout changes. Certain functionality (eg: dialogs) also would not work so would be hidden.

The full list of available syscalls can be found here.

What is Mast1c0re for PS5 and PS4?

Mast1c0re is an unpatched exploit for PS4 and PS5, which leverages a vulnerability in the PS2 emulation layer of Sony’s newer consoles. The vulnerability was disclosed, and described with great detail, by PlayStation hacker CTurt in September last year. Since then, new released have built upon the exploit, allowing in particular for emulators and PS2 ISOs to run on the PS4 and PS5.

Back then, CTurt stated Sony had no plan to fix the vulnerability, which seems to be confirmed recently with the 10.70 Mast1c0re release for PS4, and no announce from hackers that the exploit has been patched on PS5.

Download latest Mast1c0re for PS5/PS4

Mast1c0re requires you to purchase and install the game Okage on your PS4 (it is a PS2 game that you can purchase on the PSN). Remember that what you can do with the hack is fairly limited, so think carefully about purchasing that game if money is tight.

You can download the latest Mast1c0re files here. (You might have to run the compilation yourself until a binary is released). We have a basic guide on how to run the exploit here.
