PS2 Gets Integrated HDMI

February 17, 2021 by Tom Nardi 34 Comments

It might be difficult to imagine in our modern HDMI Utopia, but there was a time when game consoles required proprietary cables to connect up to your TV. We’re not just talking about early machines like the NES either, turn of the millennium consoles like the PlayStation 2, Gamecube, and the original Xbox all had weirdo A/V ports on the back that were useless without the proper adapter.

But thanks to the efforts of [Taylor Burley], you can now upgrade your Slim PS2 with integrated HDMI capability. It’s not even a terribly difficult modification, as these things go. Sure there’s a lot of soldering involved to run from the console’s A/V connector to the commercially-made HDMI dongle he’s hidden inside the case, but at least it’s straightforward work.

Tapping into the console’s A/V connector.

As [Taylor] shows in the video after the break, all you have to do is remove the proprietary connector from the HDMI adapter dongle, and wire it directly into the console’s A/V port with a bit of ribbon cable. There are only 8 pins in the connector that you need to worry about, and the spacing is generous enough that there’s no problem getting in there with your iron and some standard jumper wires. You’ve also got to pull 5 V from the board to power the adapter, but that’s easy enough thanks to the system’s nearby USB ports.

There’s a perfect spot to mount the adapter board next to the console’s Ethernet connector, and once that’s tacked down with a bit of adhesive, the only thing left to do is cut a hole in the back of the enclosure for the HDMI port and snip away a bit of the metal RF shield. Presumably the same modification could be done on the original “fat” PS2, though you’ll be on your own for finding a suitable place to mount the board.

While modern game consoles can easily emulate their earlier peers, providing enhanced graphical fidelity and introducing modern conveniences like wireless controllers in the process, there’s still something to be said for playing classic games on the original hardware. Even if these projects are fueled by little more than youthful nostalgia, it’s a safe bet we’ll continue to see folks keeping these older machines running far into the future.

VGA Without The Hassle, From Your PlayStation One

February 12, 2021 by Jenny List 45 Comments

The original Sony PlayStation was a nifty console for its day; that grey box may have only had a 33 MHz MIPS processor and 4 MB of RAM, but for the early to mid 1990s its games were some of the best to be had. From the days when it would have sat under a family TV with a composite video or RF connection, you might expect that the PlayStation would require some form of converter box to drive a higher quality monitor. As [Wesk] found out though, present on the PS1 mainboard are all the required H and V sync as well as RGB video signals to drive a VGA monitor at 15 kHz.

It’s a wallow in the past for anyone who spent the 1990s using their SMD soldering skills to install modchips in PS1s, but it’s pleasing to find that those sync lines aren’t only available from tricky-to-solder IC pins, instead they appear on handy pads. Along with RGB lines from the normal video output they’re brought out via lightweight co-ax to a VGA socket that sits in a 3D printed bracket in the space where a removed system link port would have been. A small trim of the internal shield is requited to clear the new socket, leaving the VGA port on the back of the reassembled console looking for all the world as though it was installed in the Sony factory. Given how simple this mod turned out to be and the sharpness of the resulting image, it’s surprising that this wasn’t tried back in the day. Perhaps we were all too busy playing Wipeout.

While you’re idly rekindling your interest in a PS1, should you buy one then perhaps you’ll need a modchip.

Thanks [John] for the tip.

DualShock Flight Simulator Yoke

November 4, 2020 by Danie Conradie 6 Comments

Aircraft control interfaces can be divided into stick or yoke, with the stick being more popular for flight simulators. [Akaki Kuumeri] has been designing some ingenious 3D printed adaptors for game console controllers, and his latest build is a yoke adaptor for the PlayStation DualShock Controller.

Like his previous joystick/throttle combination, this yoke makes use of a series of ball and socket links to convert the yoke’s push/pull and rotation motion into the appropriate inputs on the controller’s thumbs sticks. All the components are 3D printed except for rubber bands to provide spring tension. On the sliding contact surfaces between the different components, [Akaki] specifically designed the parts to slide along the grain (layer lines) to allow for smooth motion without resorting to bearings.

If you want an absolute minimalist yoke, tape some potentiometers to a desk drawer. Or you can go to the other end of the scale and build a complete cockpit. With the arrival of Microsoft Flight Simulator 2020, we’ll be seeing a lot of controller builds.

Burning Your Own PS1 Modchip Is Easy

November 1, 2020 by Lewin Day 18 Comments

The original Sony PlayStation came out just in time for CD piracy to really start taking off. Aware of this threat to sales, Sony engineers included a copy protection and region locking mechanism that placated executives and annoyed end-users alike. [MattKC] explores how this copy protection worked, and how you can burn your own modchip at home for just a few dollars.

Sony’s method of copy protection relied on steps taken during the manufacturing process, pressing a special groove into the game media that regular CD burners couldn’t replicate, a topic our own [Drew Littrell] has covered in depth. This groove contained a four letter code that could be read by the console, corresponding to the region in which the game was sold. The console would read this groove on startup, and check that the code in the game matched the code in the console before booting. Modchips circumvent this by injecting a spoof code into the console that matches the local region, regardless of what is read off the disc. This has the effect of both allowing users to run bootleg CD-Rs, homebrew code, as well as games from other regions.

Today, we’re blessed with the Internet and cheap hardware. As [MattKC] demonstrates, it’s no longer necessary to mail-order a chip from a dodgy ad in the back of a games magazine; instead, one can download source code and flash it to a commodity PIC microcontroller for just a few bucks. With the chip soldered in to the relevant points of the PS1’s motherboard, you’re good to go.

As far as console modding goes, the PS1 is a great platform to start with — simple to work on, and also the best selling console of all time, so the stakes are low if you mess up. Video after the break. Continue reading “Burning Your Own PS1 Modchip Is Easy” →

Clear PS2 Is The Crystal Edition We Deserved

October 15, 2020 by Lewin Day 13 Comments

Every so often, console manufacturers release a crystal edition of their hardware that never really lives up to the hype. The manufacturing realities of producing optically clear plastic mean the expense is rarely justified, even for a special edition. Instead, we get hazy, smoky translucent cases that are comparatively underwhelming. Here to rectify that, [BitHead1000] delivers on a properly transparent PlayStation2.

While the title calls it a Glass PS2, the cutting tools used and the labels on the material make it pretty clear (pun intended) that this build uses acrylic. Regardless, it’s an attractive material all on its own, and much more suited for such a build. To get the best possible visual effect, the internal shielding is removed and tossed in the bin, with plastic standoffs used to hold things in place instead. The case is then assembled around the components, giving an unparalleled view of the hardware inside.

It’s undeniably cool to watch the optical drive doing its thing inside the case when it’s switched on, and a few internal LEDs only add to the spectacle. We’ve seen [BitHead1000] pull off other casemodding feats, too, such as the fire breathing N64. Video after the break.

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” →

The Mini Console Revolution, And Why Hackers Passed Them By

August 27, 2020 by Lewin Day 31 Comments

The Raspberry Pi was initially developed as an educational tool. With its bargain price and digital IO, it quickly became a hacker favorite. It also packed just enough power to serve as a compact emulation platform for anyone savvy enough to load up a few ROMs on an SD card.

Video game titans haven’t turned a blind eye to this, realising there’s still a market for classic titles. Combine that with the Internet’s love of anything small and cute, and the market was primed for the release of tiny retro consoles.

Often selling out quickly upon release, the devices have met with a mixed reception at times due to the quality of the experience and the games included in the box. With so many people turning the Pi into a retrogaming machine, these mini-consoles purpose built for the same should have been immediately loved by hardware hackers, right? So what happened?
