Overview
- A developer known as Gezine demonstrated the mast1c0re method running through the PS4 disc of Star Wars: Racer Revenge on PS5 firmware 12.0, but the code has not been released.
- Resale listings have surged from tens of dollars to roughly $250–$500, with some asking prices even higher on marketplaces such as eBay.
- Reports say the approach requires the 2019 Limited Run physical disc rather than digital copies, and sales data indicate only about 8,500 units were produced.
- Coverage cites a long-standing Hall of Fame menu bug in Racer Revenge as the code-injection entry point leveraged through PS5’s backward-compatibility layer.
- A New Year’s leak of PS5 ROM keys is aiding research, but homebrew developers caution that additional components are needed for a full public jailbreak and Sony has not commented.
