UltraC0re — Jak X (PS2-on-PS5) userland exploit

A userland code-execution entry point for Jak X via the PS5's PS2 emulator, built on
Luac0re by Gezine. From a crafted save it reaches native
code in the emulator and brings up a remote Lua loader on port 8888, which can host Luac0re's
PS5 jailbreak payloads (poops).

What's in this release

  • SCUS-97429 — the crafted Jak X save (NTSC, SCUS-97429) with the UltraC0re framework baked in.
  • poops.lua — PS5 kernel-exploit payload (send it over the loader).

Requirements

  • Jak X: Combat Racing (NTSC, SCUS-97429 / CUSA07842) installed on the PS5.
  • A way to re-sign PS5 save data for your own account (e.g. Garlic Save Manager).

Install

  1. Re-sign the save for your own PSN account — guide: https://github.com/n0llptr/remote_lua_loader/blob/main/SETUP.md
  2. Import it to the PS5 (USB save import).
  3. Launch Jak X → load the save → Adventure mode. When the cutscene starts, press △ to skip it; the loader dialog appears (Listening :8888).
  4. From your PC, send a payload to <PS5-IP>:8888 to run it (e.g. poops.lua for the jailbreak).

Notes

  • Only poops has been tested. Built on Gezine's Luac0re; full credits in the README.
