PS5SX2, an app that lets jailbroken PlayStation 5 consoles run PlayStation 2 games, has become the center of a fast-moving homebrew scene on Reddit, according to Mashable.
Sony dropped backward compatibility starting with the PS4 in 2013, making the app's existence notable on its own.
Version 1.00 shipped with bugs that users traded fixes for; a 2.00 update followed within roughly two weeks, adding frame generation and multi-disc support, and one community post claims PS3 games now run on jailbroken PS5s too.
A separate exploit chain called Relapse, released in late September by developer Nathan Fargo, covers firmware versions 7.00 through 13.60, extending past the prior public jailbreak's ceiling of 12.70 and working on any console that hasn't installed Sony's firmware 14.00, released Sept. 16.
Console jailbreaking has historically moved slowly because it is both legally fraught, falling under the Digital Millennium Copyright Act, and technically demanding, requiring deep firmware expertise to a small circle of hackers.
That cycle is compressing, and AI coding assistants appear to be a factor, though there is no confirmation the Relapse developers used AI tools.
Evidence seems to point to decompilation, the process of rebuilding readable source code from a game's compiled binary, which once took volunteers years for projects like the unofficial Super Mario 64 PC port.
Hundreds of AI-decompiled emulators and games have surfaced in recent weeks crediting Anthropic's Claude Opus 5.5, including browser ports of Halo: Combat Evolved, Grand Theft Auto: Vice City and Skate 3.
