Subverting PS4 And PS5 Through The PS2 Emulator

October 3, 2022 by Arya Voronova 7 Comments

Game console hacking remains a fascinating area, and we’re glad when someone brings the spoils of exploration for us to marvel at. This time, we’re looking at the [mast1c0re] hack story by [cturt] – an effort to find bugs in PS2 emulation toolkit present on Sony PlayStation 4 and 5 consoles, proving fruitful in the end. What’s more, this exploit seems unpatchable – not technically, but under the Sony’s security practices, this emulator falls under the category of things they refuse to patch when identified.

In this story, we’re taken on a journey through the PS2 emulator internals, going through known-exploitable PS2 games and learning about a prospective entry point. Circling around it, collecting primitives and gadgets, bypassing ASLR on the way there, the emulator is eventually escaped, with a trove of insights shared along the way. As a demonstration, [cturt] successfully loaded a different PS2 game from outside the PS2 emulator, transferring it to the PS4 over WiFi!

PS5 Goes On Slim-Fast

June 20, 2022 by Matthew Carlson 28 Comments

For the past few decades, most console makers have first come out with a large flagship model, and then a few years later, released a smaller, more compact slim edition. Not content to wait for it, [Matt] at DIY Perks made his own PS5 Slim, and the results are awe-inspiring.

Generally, slim editions are made by lowering the TDP of the chip under the hood. A lower power draw means less cooling is needed, a smaller power supply can be used, and a design that is overall easier to manage. Unfortunately, [Matt] had none of these benefits and instead had to contend with the full 180 W that the AMD CPU inside the PlayStation can draw.

Taking apart the console left him with the main board that was quite thick as it had heat pipes on both sides. His first thought was water cooling as it can rapidly move the heat needed, but even with right-angle fittings, it didn’t fit within the ambitious thickness goal he had set for himself of less than 2 cm (about 3/4″). To do that, [Matt] had to fabricate a copper water block from three sheets of copper. The first one connects to the motherboard via standoffs and has cut-outs for various connectors and parts. The middle layer has a channel through which water can flow, and the last layer seals it together.

With the three layers together, he soldered them in a toaster oven repurposed as a reflow oven. Cleverly, he used silicone grease to prevent solder from getting into areas he didn’t want, like the fins in the CPU block. Luckily, the grease dissolved in alcohol, and after flushing the chamber, he had a solid copper, water-tight, custom loop. However, on his road to glory, [Matt] ran into a snag. He accidentally covered the intake vent on the radiator, and the PS5 overheated, killing it. With a fried mainboard and a project almost on the cusp of completion, he resorted to using the PS5 he had received for B-roll.

Last-minute motherboard swap aside, the final project is gorgeous. The polished exterior and sheer thinness of it are striking. [Matt] has already disguised his PS5 before and after this, we’re not quite sure where he could possibly take it next. But we’re excited to find out.

Disguising The PS5 With A Custom Wood And Carbon Fiber Enclosure

May 26, 2021 by Danie Conradie 8 Comments

The PlayStation 5 has a very distinctive enclosure that some love and others hate. Its design certainly does not lend itself to lying on its side, even though this is a more practical orientation for putting on a shelf in a TV console. [Matt] from [DIY Perks] decided to address this and built a custom wood and carbon fiber PS5 enclosure that looks good in any orientation.

He started by disassembling his PS5 and taking out only the main electronics unit, fan, and power supply. These were mounted on a carbon fiber baseplate using hexagonal threaded standoffs. The sides of the enclosure were constructed from dark walnut, with holes cut in the front and back for connectors and airflow. A long recess was cut in the front hole and covered with an ingenious carbon fiber cover which opens if you press it at one end and acts as the power button if you press it at the other end.

Matt paid close attention to the airflow routing of the original enclosure and copied it to the new one. Like the original, he used adhesive foam strips to direct the air through the heat sinks. The top cover is also carbon fiber, with an elegant honeycomb hole pattern with wood inserts for the air intake.

This is not [Matt]’s first custom PS5 enclosure. The other was a significantly more flashy brass incarnation of the original. Other custom enclosure he’s made include a wood PC case and a brass encased USB-C monitor. Continue reading “Disguising The PS5 With A Custom Wood And Carbon Fiber Enclosure” →

High-End Case Mods To A PlayStation 5

March 30, 2021 by Lewin Day 10 Comments

Modern consoles bring joy to televisions around the globe, but they’re fundamentally mass-produced totems to gaming excellence. That wasn’t good enough for [Matt], who decided that his PlayStation 5 needed a total case makeover. (Video, embedded below.)

The material of choice is brass. Capable of being polished to a mirror-like shine while being readily workable and available, it’s perfect for making a PlayStation 5 look just a little more deluxe. While [Matt] has worked with brass before, replicating the PS5’s case in the metal pushed him to learn new skills. The main center divider was easy enough, with paper used to create a cutting template to match the form which bends through 90 degrees. The real challenge, however, was the side panels. With complex curves across several axes, manually bending metal plates to match the shape proved impossible. Instead, a custom wooden and plaster jig was made, onto which brass plates could be clamped to match the curves. A blowtorch was then used to release the plate’s internal stresses in a process called normalisation.

[Matt] does a great job of making the whole thing look easy. With that said, the final results are stunning enough that we’re sure it would be difficult to replicate without a lot of experience and attention to detail. In particular, the deft way the side panel clips were dealt with had us nodding in sage approval. The final console makes a great companion for the brass-housed monitor [Matt] created for his [DIY Perks] channel quite recently. Video after the break.

Console Identity In The Age Of PlayStation 5 And Xbox Series

October 26, 2020 by Drew Littrell 22 Comments

Consoles are obsolete the minute they are released. The onward march of silicon innovation ensures that consoles never are able to keep up with the times, but technical superiority rarely results in being remembered. That kind of legacy is defined by the experiences a device provides. A genre defining game, a revolutionary approach to media, or a beloved controller can be enough to sway popular opinion. But really…it all boils down to a box. All the spurious promises of world-class hardware specs, all the overly ambitious software ship dates, and even the questionable fast-food crossover promotions exist in service to the box. The boxes vying for attention in 2020 A.D. are the PlayStation 5 (PS5) and Xbox Series X/S/Seriessss (XSX or whatever the common nomenclature eventually shakes out to be). These boxes likely represent the minimum spec for the next decade in big-budget video games, however, it is the core identity of those consoles that will define the era.

Official Teardown Gives Unexpected Look Into PS5

October 7, 2020 by Tom Nardi 65 Comments

With Sony and Microsoft still a month away from the public release of their next-generation game consoles, you’d expect technical details of their respective systems to still be under a veil of secrecy. But both companies look to be taking things a bit differently this generation, as it becomes increasingly clear that modern consumers are interested in what makes their devices tick. Today, Sony really threw down the gauntlet by beating the tech media to the punch and posting their own in-depth teardown on the new PlayStation 5.

Unsurprisingly, the video after the break is almost entirely in Japanese. But even if you don’t know the language, there’s plenty of interesting details to be had. For one thing, the heatsink and fan that cools the PS5’s AMD CPU and GPU are collectively so massive that they appear to take up most of the console’s internal volume.

In fact, the heatsink itself is so large that the motherboard is actually mounted to it instead of the other way around. So if you want to take out the board, you have to unbolt it from the heatsink and remove it first. In the process you’ll expose the unique liquid metal thermal compound that Sony apparently developed specifically for this application. Good luck to you if any dust gets in that expensive-looking goop.

It’s also interesting to note that, unlike the previous two generations of Sony consoles, the PS5 has no discrete hard drive. Instead, onboard flash with a custom controller is used to provide 825 GB of storage for software. Hopefully Sony has put the requisite amount of R&D into their wear leveling, as a shot flash chip will mean a whole new motherboard. That said, gamers with extensive collections will be happy to see there appears to be an expansion bay where you can install your own M.2 drive.

Between this and the recent PS4 assembly line tour, it’s refreshing to see a company like Sony be a bit more transparent. After years of adversarial treatment from the tech giants, we’d almost forgotten that the customer is supposed to be king. Continue reading “Official Teardown Gives Unexpected Look Into PS5” →
