Super NES Cartridge Pulls A Sneaky, Plays Minecraft

August 31, 2023 by Donald Papp 24 Comments

Sometimes it’s the little touches and details that make a project. That’s certainly the case with [Franklinstein]’s Super Nintendo (SNES) Cartridge Hard Drive. It might only be an enclosure for a solid-state hard drive with a USB interface, but the attention to detail is what really makes it worth checking out.

A SNES cartridge has a pretty standard clamshell-ish construction, but fitting the solid-state drive plus cable adapter turned out to be a bit of a challenge.

Since [Franklinstein] wanted the cartridge to look as original as possible, careful measuring and cutting was needed to securely fit the drive and provide an unobtrusive USB-C port tucked discreetly into the cartridge’s opening. We like the technique of using a 3D printed fixture to take up the slack on the cable by exactly the right amount, resulting in a 100% rattle-free end product. A custom Minecraft sticker label provides the finishing touch.

Being able to plug it into a computer and actually play Minecraft is a neat gimmick, but it really shows that some careful construction and assembly can be what makes something look like a clean build instead of a hack job. Take a look at additional build detail and pictures, and check out the video of the build, embedded below.

Hey, if sneaky cartridge mod tricks intrigue you, then you’ll absolutely want to check out how it was possible to play DOOM on a NES from a cartridge. Maybe that’s the next evolution for a cartridge with a Minecraft label on it?

New Year Habits – What Do You Do For Data Storage?

January 20, 2020 by Bob Baddeley 109 Comments

2020 is a year of reflection and avoiding regret, and one of the biggest practices we all know we should do better is back up our data. Inevitably there will be a corruption or accident, and we mourn the loss of some valuable data and vow to never let it happen again, and then promptly forget about good data retention practices.

I believe life is about acquiring memories, so it makes sense to me to try to archive and store those memories so that I can reflect on them later, but data storage and management is a huge pain. There’s got to be a better way (cue black and white video of clumsy person throwing up arms in disgust).

Nice Cloud You Have There; Shame if Something Happened to It

The teens of the century saw a huge shift towards cloud storage. The advantages of instantly backing up files and using the cloud as the primary storage for all your devices is appealing. It’s now easier to transfer files via the cloud than with a cable. With Google Docs and WordPress we have our most important documents and writing stored as database blobs on someone else’s servers. Facebook and Google and Flickr record all of our memories as photo albums. Unlimited storage is common, and indexing is so good that we can find photos with a vague description of their contents.

These things are instantly accessible, but lack permanence. Gone are newspaper clippings and printed photos discovered in a shoebox. When we aren’t in control of those services, they can disappear without any warning. Even some big offerings have packed up shop, leaving people scrambling to back up data before the servers were shut down. Google Plus is closed, Yahoo Groups is closed, MySpace lost all content created prior to 2016, GeoCities closed in 2009, and Ubuntu One closed in 2014. It’s safe to say that no online content is safe from deletion. It’s also safe to say that cloud storage is a difficult location from which to extract your data.

With the risk of data leaks and privacy violations occurring daily, it’s also safe to say that some of your files should probably not be stored in the cloud in the first place. So, how do we do it well, and how do we get in the habit of doing it regularly?

Fail Of The Week: Careful Case Mod Is All For Naught

July 12, 2018 by Tom Nardi 20 Comments

Today’s entry comes to us from [Robert Tomsons], who was kind enough to document this crushing tale of woe so that we might all learn what true heartbreak is. If you’ve ever toiled away at getting that perfect surface finish with body filler, this one is going to hurt. In fact, you might just want to hit that “Back” button and head to safety now. There’s probably a pleasant story about some 3D printed thing being used with a Raspberry Pi of some sort that you can read instead.

For those of you brave enough to continue on, today we’ll be looking at what [Robert] thought would be a simple enough project. Seeing the board from a USB 3.0 external hard drive kicking around his parts bin, he had a rather unusual idea. Wanting to add an extra drive to his computer, but liking the idea of being able to independently control its power, he decided to integrate the external drive into machine’s front panel. This would not only allow him to power off the secondary drive when not in use, but it meant he could just plug his laptop into the front panel if he wanted to pull files off of it.

All [Robert] needed to do was make it look nice. He carefully squared off the edges of the external drive’s back panel to roughly the size of the computer’s 3.5 inch drive bay opening. He then glued the piece in place, and began the arduous task of using body filler to smooth everything out. It’s a dance that many a Hackaday reader will know all too well: filler, sand, primer, sand, filler, sand, primer, sand, so on and so on. In the end, the final result looked perfect; you’d never have thought the front panel wasn’t stock.

It should have been so easy. Just snap the case back together and be done with it. But when [Robert] finally got the machine buttoned back up and looked at the front, well, it’s safe to say his day couldn’t get much worse. Maybe the glue was not up to the task. Perhaps it was how excited he was to get the case put back together; a momentary loss of muscular coordination. A few extra foot-pounds of energy per second, per second. Who can say?

[Robert] says he’ll return to the project, but for now he needs a break. We agree. Interestingly, he mentions in his post that his body filler work was inspired by [Eric Strebel], a name that is well known around these parts. Considering how good it looked before it exploded, we’ll consider that high praise.

Cracking An Encrypted External Hard Drive

March 16, 2018 by Tom Nardi 13 Comments

As far as hobbies go, auditing high security external hard drives is not terribly popular. But it’s what [Raphaël Rigo] is into, and truth be told, we’re glad it’s how he gets his kicks. Not only does it make for fascinating content for us to salivate over, but it’s nice to know there’s somebody with his particular skill set out there keeping an eye out for dodgy hardware.

No word on how the “Secret Wang” performs

The latest device to catch his watchful eye is the Aigo “Patriot” SK8671. In a series of posts on his blog, [Raphaël] tears down the drive and proceeds to launch several attacks against it until he finally stumbles upon the trick to dump the user’s encryption PIN. It’s not exactly easy, it did take him about a week of work to sort it all out, but it’s bad enough that you should probably take this particular item off the wishlist on your favorite overseas importer.

[Raphaël] treats us to a proper teardown, including gratuitous images of chips under the microscope. He’s able to identify a number of components on the board, including a PM25LD010 SPI flash chip, Jmicron JMS539 USB-SATA controller, and Cypress CY8C21434 microcontroller. By hooking his logic analyzer up to the SPI chip he was able to dump its contents, but didn’t find anything that seemed particularly useful.

The second post in the series has all the gory details on how he eventually gained access to the CY8C21434 microcontroller, including a description of the methods which didn’t work (something we always love to see). [Raphaël] goes into great detail about the attack that eventually busted the device open: “cold boot stepping”. This method allowed him to painstakingly copy the contents of the chip’s flash; pulling 8192 bytes from the microcontroller took approximately 48 hours. By comparing flash dumps he was able to eventually discover where the PIN was being stored, and as an added bonus, found it was in plaintext. A bit of Python later, and he had a tool to pull the PIN from the drive’s chip.

This isn’t the first time we’ve seen a “secure” hard drive that ended up being anything but. We’ve even been witness to a safe being opened over Bluetooth. Seems like this whole “Security by Obscurity” thing might not be such a hot idea after all…
