Hackaday Links: June 14, 2026

Times are tough out there, and many are starting to feel the pressure at the grocery store checkout line or the gas pump. But whenever you start to worry about affording life’s necessities, take comfort in the knowledge that somebody is so flush with cash that on Friday they decided to treat themselves and spend $3 million for a sealed copy of Super Mario Bros for the Nintendo Entertainment System.

Although we’re not going to say it necessarily justifies the insane price — a new record for the most ever paid for a video game, incidentally — Heritage Auctions does note in their press release that this is an exceptionally rare version of what’s admittedly one of the most iconic pieces of software ever produced. This is only one of three copies of this particular variant known to exist, which Nintendo apparently distributed to test markets in the United States ahead of the game’s official 1985 release.

In slightly more modern gaming news, Asha Sharma, the new head of Microsoft’s Xbox division, has been making some big swings to try and get Microsoft’s gaming division back on track after years of declining sales. As part of that effort, she recently penned an article detailing some of the challenges the company is facing, which includes some interesting hardware details.

According to the blog post, she claims that in February, the cost of memory and storage components for the Xbox console had doubled compared to the previous year. But those numbers have jumped again, and by the time the holidays roll around, she expects they’ll be paying five times what they did in 2024. That’s bad news for anyone looking to put an Xbox under the tree come Christmas, but even worse news as the company works on the console’s successor. Considering that today’s hardware from Sony and Microsoft can already set you back $700 USD depending on which version you get, it seems like we’re approaching a point where gaming consoles could price themselves out of the market.

Just How Vulnerable To Accidental Erasure Are EPROMs Anyway?

On the scale of things worth worrying about, having to consider whether your EPROMs will be accidentally erased by some stray light in the shop is probably pretty low on the list. Still, losing irreplaceable data can make for a bad day, so it might just pay to know what your risks really are.

To address this question, [Adrian] set out to test just how susceptible to accidental erasure some common EPROM chips are. An EPROM, or “erasable programmable read-only memory”, is a non-volatile memory chip that can be programmed electrically and then erased optically, by exposing the die inside the chip to light at a specific wavelength, usually in a special chip erasing tool. But erasure can also happen in daylight (even if it takes a few weeks), so [Adrian] cooked up an experiment to see what the risk really is.

He exposed a selection of EPROMs with known contents to UV and checked their contents. Three of the chips had a simple paper or foil label applied, while one had its quartz window exposed to the UV. As expected, the unprotected chip was erased in just 30 minutes. The covered chips, though, all survived that onslaught, and much more — up to 780 minutes of continuous exposure.

So rest easy — it seems that even a simple paper label is enough to protect your precious retro EPROMs. It’s a good data point, and hats off to [Adrian] for taking a look at this. But now we can’t help but wonder: what would a little sunscreen applied to the quartz window do to erasability? Sounds like a fun experiment, too.
