OG DOOM Shows Off The Origins Of Multi-Monitor

February 7, 2023 by 13 Comments

We have a thing for DOOM, and we admit it. The source was released, and clever hackers have ported the engine to every system imaginable. It’s a right of passage, when hacking a machine, to run DOOM on it — be it a VoIP phone, or tractor. But the original 1993 release does have a few notable tricks, and there’s something to be said for recreating that experience on period hardware. And that’s what we’re covering today: [Tech Tangents] discovered DOOM’s multi-monitor support, and built a 4-computer cluster to show it off.

There is a catch, of course. DOOM 1.1 has the multi-monitor support, and under-the-hood, it works by running a copy of the game on individual computers, and controlling the drones over the network. As the game’s network code was updated for version 1.2, the multi-monitor feature was axed to make the network code easier to maintain. So, find a 1.1 shareware release, install it on a DOS machine with IPX drivers, and start each iteration with a -net flag. Use -left and -right to set the drones to the appropriate view. And that view is ninety degrees left and right.

Maybe not ideal, but at the time it was one of the first games to have any sort of multi-monitor support at all. Likely inspired by a commercial flight simulator setup. Either way, it’s a neat feature, and kudos to [Tech Tangents] for showing off this obscure feature of a beloved classic!

Electronic Shoe Explores Alleged Chess Misbehavior

February 1, 2023 by 20 Comments

A few months ago, a scandal erupted in the chess world which led to some pretty wild speculation around a specific chess player. We won’t go into any of the details except to say that there is virtually no physical evidence of any method this player allegedly used to cheat in a specific in-person chess match. But [Teddy Warner] and partner [Jack Hollingsworth] were interested in at least providing a proof-of-concept for how this cheating could have been done, though, and came up with this device which signals a chess player through a shoe.

The compact device is small enough to fit in the sole of one of the player’s shoes, and is powered by an ATtiny412 microcontroller paired with a HC-06 Bluetooth module. The electronics are fitted into a 3D printed case along with a small battery which can then be placed into the sole of a shoe, allowing the wearer to feel the vibrations from a small offset-weight motor. With a second person behind a laptop and armed with a chess engine, the opponent’s moves can be fed into the computer and the appropriate response telegraphed through the shoe to the player.

While [Teddy] and [Jack] considers the prototype a success in demonstrating the ease at which a device like this could be used, and have made everything related to this build open source, this iteration did have a number of issues including that the motor buzzing was noticeable during play, and that his chess engine made some bizarre choices in the end game. It also requires the complicity of a second person, which is something this other chess cheating machine does away with. They also note that it’s unlikely that any chess players at the highest levels use devices like these, and that other chess experts have found no evidence of any wrongdoing in this specific scandal.

Wizards Get Creative, Maybe Save The World

January 30, 2023 by 12 Comments

While it’s not normal Hackaday fare, we’ve covered the Dungeons & Dragons licensing kerfuffle, partially because we’re all nerds at heart, and also because it’s worrying that an Open Source styled license could be “deauthorized”. I did touch base with the Open Source Initiative, and got a telling comment that this issue was outside their purview, as the OGL 1.0a didn’t rise to the definition of an OSI approved license, and the update looked to be a disaster.

Since our coverage was published, Wizards of the Coast released part of the Fifth Edition System reference Document (SRD) under a Creative Commons license, removed the profit sharing language from the OGL update, but notably left the language in place about deauthorizing the 1.0a version of the license. As you can imagine, fans were still unamused, and we informed WotC of our displeasure when they launched a survey, asking fans their thoughts on the new license.

And the outpouring was overwhelming, with over 15,000 survey responses in just over a week. The vast majority (90% for some questions) informed WotC that they had lost their collective minds. That response, combined with a plummeting subscription count on DND Beyond, Paizo’s explosion of popularity and new ORC license announcement, and the plethora of publishers jumping ship, has finally shone the light of reason upon management at WotC.

The latest announcement is a win in basically every regard. The OGL 1.0a will not be deauthorized, and the entire 5e SRD has been released under the Creative Commons 4.0 By Attribution license. That’s an interesting choice, as CC-BY-4.0 is a very permissive license. It’s not “viral”, as it does not place any licensing restrictions on derivative works, and there are no restrictions on commercial use. The only restriction is that attribution must be included. The latest SRD is now available under both licenses, you pick your preference. So as a reward for going through the trauma, we get a sizable chunk of the game under an even less restrictive license. Bravo.

Original Controller Ports In Custom Case Means Retro Gaming In Style

January 28, 2023 by 34 Comments

Some careful measuring and a little extra effort can be all that separates what looks like a hack job from a slick end product, and that is apparent in [Eric Sorensen]’s classy retrogaming rig, complete with ports for original console controllers.

Neatly housing these components in a case makes all the difference.

[Eric] likes his vintage gaming, and was terrifically pleased with MiSTer, an open-source project that recreates various classic computers, game consoles and arcade machines using modern FPGA-based hardware. Of course, what makes retro gaming even better is using a platform’s genuine original controllers, which just takes a little extra hardware and wiring.

But [Eric] found that all the required accessories and peripherals started to look awfully cluttered. He solved this issue by packing everything carefully into a specialty PC case called the Checkmate A1500 Plus, which gives off a strong 80s design vibe. As a bonus, the front panels are all removable and that’s where [Eric] decided to house the custom controller ports.

First [Eric] carefully measured each controller connector to create CAD models, then designed matching front panels to house the connectors and 3D printed them. Once that was done, post-processing the panels was a long process of apply Bondo, sand, paint, and repeat as needed. The results looks fantastic, and this project is a prime example of how aesthetics and finish can matter.

Find yourself in a similar situation? [Tom Nardi] has shown us all that 3D prints don’t have to look 3D-printed, and careful application of paint and primer can really put the ‘pro’ in prototyping.

Wolfenstein 3D, As You Never Imagined It.

January 27, 2023 by 21 Comments

When tracing the history of first-person shooting (FPS) games, where do you credit with the genesis of the genre? Anyone who played 3D Monster Maze on the Sinclair ZX81 might dare to raise a hand, but we’re guessing that most of you will return to the early 1990s, and id Software. Their 1992 title Wolfenstein 3D might not have been the first to combine all the elements, but it’s arguably the first modern FPS and the first to gain huge popularity. Back in 1992 it needed at least a VGA card and a 286 to run, but here in 2023 [jhhoward] has taken it back a step further. You can now slay virtual Nazis in 3D on an 8088 PC equipped with a lowly CGA card.

Whether the gameplay survives in the sometimes-bizarre CGA color schemes and whether it becomes too pedestrian on an 8088 remains as an exercise for the reader to discover, but it’s a feat nevertheless. The textures all need converting to CGA mode before they can be used and there are even versions for the shareware and paid-for versions of the game.  It’s possible that an 8088 may never be able to say yes to “Will it run DOOM?”, but at least now it can run the predecessor.

Casting Custom Resin Buttons For The Steam Deck

January 26, 2023 by 11 Comments

If you play games on multiple consoles, you’re probably familiar with the occasional bout of uncertainty that comes with each system’s unique button arrangement. They’re all more or less in the same physical location, but each system calls them something different. Depending on who’s controller you’re holding, the same button could be X, A, or B. We won’t even get started on colors.

Overhearing her partner wish the buttons on his Steam Deck matched the color scheme of the Xbox, [Gina Häußge] (of OctoPrint fame) decided to secretly create a set of bespoke buttons for the portable system. There was only one problem…she had no experience with the silicone molding process or epoxy resins which would be required for such an operation.

Toothpicks were used to make channels in the mold.

Luckily we have the Internet, and after researching similar projects that focused on other consoles, [Gina] felt confident enough to take apart Steam’s handheld and extract the original plastic buttons. These went into a clever 3D printed mold box, which was small enough to put into a food vacuum container for degassing purposes. The shape of the buttons necessitated a two-piece mold, into which [Gina] embedded two channels: one to inject the resin, and another that would let air escape.

The red, green, blue, and yellow resins were then loaded into four separate syringes and forced into the mold. It’s critically important to get the orientation right here, as each button has a slightly different shape. It sounds like [Gina] might have mixed up which color each button was supposed to be during an earlier attempt, so for the final run she made a little diagram to keep track. After 24 hours she was able to peel the mold apart and get a look at the perfectly-formed buttons, but it took 72 hours before they were really cured enough to move on to the next step.

[Gina] applied the legends with a sheet of rub-on lettering, which we imagine must have been quite tricky to get lined up perfectly. Since the letters would get worn off after a few intense gaming sessions without protection, she finally sealed the surface of each button by brushing on a thin layer of UV resin and curing it with a flashlight of the appropriate wavelength.

There are a fair number of steps involved, and a fair bit of up-front cost to get all the materials together, but there’s no denying the final result looks phenomenal. Especially for a first attempt. We wouldn’t be surprised if the next time somebody wants to head down this particular path, it’s [Gina]’s post that guides them on their way.

Inside The Atari 2600

January 15, 2023 by 17 Comments

The Atari 2600 was an extremely popular yet very simple game console back in the 1970s. They sold, apparently, over 30 million of them, and, of course, these things broke. We’d get calls from friends and — remember, back then normal people weren’t computer savvy — nine times out of ten, we’d ask them to swap the controllers to show them it was a bad controller, and problem solved. But if you did have to open one up, it was surprising how little there was inside, as [Steve] notes in his recent teardown.

The bulk of the circuit board was switches, the power supply, and a TV modulator if you remember those. The circuit board was a tiny thing with a shrunk-down 6502, a 6532 RIOT chip, and a custom chip called a TIA. If you are familiar with those chips, you might wonder if the TIA had any memory in it. It didn’t. Nearly all the ROM and RAM for the game lived in the cartridge itself. Sure, the RIOT has 128 bytes of memory, but that’s not much.
