PS5SX2 Brings Back Physical PS2 Discs
The app driving most of the buzz is PS5SX2, a native port of the PC emulator PCSX2 built by a developer known as Sword. Early versions let jailbroken PS5s run PS2 games from disc images, but a recent 2.01 update added something more striking: the ability to insert an original PS2 disc into the PS5’s drive and have it dump and launch directly. It isn’t true backward compatibility since each disc has to be dumped once before it will run, but it’s the closest the PS5 has come. Sword has reportedly confirmed PS3 disc support is next.
Running alongside PS5SX2 is Relapse, a separate jailbreak exploit chain released by developer Nathan Fargo in late September. It covers firmware 7.00 through 13.60, a wider range than the previous public jailbreak’s 12.70 ceiling, and works on any PS5 that hasn’t been updated to firmware 14.00.
Claude Is Listed as a Contributor, Not Just “Credited”
What sets this jailbreak wave apart from earlier ones is how openly AI-assisted it is. Sword has described PS5SX2 as an AI-assisted project, and Claude is listed among the three contributors on its GitHub repository rather than just mentioned in passing. Decompiling, the process of rebuilding readable source code from a game’s compiled binary, used to take skilled hackers years. AI models can now write, test, and iterate on that work without fatigue, which has produced hundreds of AI-decompiled emulators and game ports in recent weeks, many crediting Claude Opus 5.5.
Not everyone sees this as progress. Developers behind fan projects like Zelda: Recompiled have pushed back on AI-generated knockoffs as disrespectful to the original reverse-engineering work, and critics point out that many of these AI-assisted ports ship buggy or incomplete.
Original PS2 Discs Still Command a Premium
The irony is that while emulation gets easier, physical copies of certain PS2 games keep climbing in price on the secondhand market:
- Marvel vs. Capcom 2 (2002): $80 to $100
- Silent Hill: Shattered Memories (2009): around $500, with some listings near $700
- Haunting Ground (2005): over $500, sealed copies topping $1,000
- Rule of Rose (2006), never officially released in the US: over $1,000, with some sales reaching $5,000
- Kuon (2004), an early FromSoftware title: over $2,000
None of that scarcity goes away because an emulator exists. If anything, easier emulation just makes the originals more of a collector’s trophy than a way to actually play the game.
Confirmed on GitHub, Unconfirmed Everywhere Else
The PS5SX2 case is the rare one where AI’s role isn’t speculation, since Claude’s name sits directly in the project’s contributor list. But most of the hundreds of other AI-decompiled emulators and ports circulating right now carry no such confirmation, just a credit line in a changelog. That distinction matters for anyone trying to gauge how much of this boom is genuinely AI-driven versus developers attaching AI branding to code they’d have written anyway. Jailbreaking also still voids warranties and risks bricking a console outright, a costly mistake given how expensive PS5 hardware remains right now.
