DOOM Runs On Husqvarna’s Robot Lawnmower

DOOM has been ported to a lot of platforms — to the point where the joke is kind of getting old now. Evidence of that is available in the fact that brands are now getting in on the action. Yes, as reported by The Register, you can now officially play DOOM on your Husqvarna’s Automower.

Nice, right? Speedrun it on this interface.

We had to check if this was some kind of joke; indeed, the April release date had us looking at the calendar. However, it seems to be legit. You’ll be able to download a version of DOOM via the Husqvarna Automower Connect App, and play it on the tiny screen of your robot lawnmower. Hilariously, due to the size of the game, Husqvarna notes it “may take up to a week before the game is playable” due to the time it takes the mower to download it, along with a necessary software update.

Controls are simple. The knob on the robot is used for turning left and right, while pressing start lets you run forward. Firing weapons is done by pressing the control knob.

We’ve seen some quality ports before, including an arcade port that was particularly cool. Really, though, at this stage, you have to work harder to impress. Show us DOOM running on a Minuteman launch console or something. Continue reading DOOM Runs On Husqvarna’s Robot Lawnmower”

Air Hockey Table Embraces DOOM, Retro Gaming

[Chris Downing] recently finished up a major project that spanned some two years and used nearly every skill he possessed. The result? A smart air hockey table with retro-gaming roots. Does it play DOOM? It sure (kind of) does!

Two of the most striking features are the score board (with LCD screen and sound) and the play surface which is densely-populated with RGB LED lighting and capable of some pretty neat tricks. Together, they combine to deliver a few different modes of play, including a DOOM mode.

The first play mode is straight air hockey with automated score tracking and the usual horns and buzzers celebrating goals. The LED array within the table lights up to create the appearance and patterns of a typical hockey rink.

DOOM hockey mode casts one player as Demons and the other as the Doom Slayer, and the LED array comes to life to create a play surface of flickering flames. Screams indicate goals (either Demon screams or Slayer screams, depending on who scores!)

In retrogaming emulation mode, the tabletop mirrors the screen.

Since the whole thing is driven by a Raspberry Pi, the table is given a bit of gaming flexibility with Emulation Mode. This mode allows playing emulated retro games on the scoreboard screen, and as a super neat feature, the screen display is mirrored on the tabletop’s LED array. [Chris] asserts that the effect is imperfect, but to us it looks at least as legible as DOOM on 7-segment displays.

This project is a great example of how complex things can get when one combines so many different types of materials and fabrication methods into a single whole. The blog post has a lot of great photos and details, but check out the video (embedded below) for a demonstration of everything in action.

Playing The Guitar Of DOOM

Over the years, we’ve seen DOOM run on pretty much everything from an 8088 to a single keycap. We’ve also written up one or two controllers, but we don’t think we’ve ever seen anything like this — playing DOOM with an electric guitar.

The guitar in question is a Schecter Hellraiser Deluxe, which seems like a great choice to us. In order to get the notes to control the game, [DOS Storm] converted a handful of notes to MIDI using a VST plugin called Dodo MIDI 2 and the Reaper DAW. Then it was a matter of converting MIDI to keystrokes. This took two programs — loopMIDI to do take the MIDI data and route it elsewhere, and MIDIKey2Key to actually convert the MIDI to the keystrokes that control DOOM.

The result is that the notes that move Doomguy around are mostly in an A-major bar chord formation, with some controls up in the solo range of the fret board. Be sure to check out the demo video below and watch [DOS Storm] clear level one in a fairly impressive amount of time, considering their controller is a guitar.

That key cap isn’t even the most ridiculous thing we’ve seen DOOM running on. It’s probably a toss-up between that and the LEGO brick.

ZX Spectrum Gets A 3D FPS Engine

The Sony PlayStation and Nintendo 64 are well-known for bringing 3D gaming into the mainstream in a way that preceding consoles just couldn’t. The ZX Spectrum, on the other hand, is known for text adventures and barebones graphics. However, it now has a rudimentary version of a Quake-like engine, as demonstrated by [Modern ZX-Retro Gaming].

As you might expect, the basic ZX Spectrum that sat in front of your dodgy old TV in the 1980s isn’t really up to the task of running a full 3D game. The engine runs at a fairly jerky frame rate on a 3.5 MHz ZX Spectrum, with purely monochrome graphics. However, the game can run more smoothly on 7, 14, and 28MHz ZX Spectrum compatibles. As with many such projects, most of the video you’ll see is of the game running in emulators. Impressively, the game features sound effects, three weapons, and a standard WASD control layout as per modern FPS games.

If you’re wondering about the confusing visuals, there’s a simple explanation. Yes, the UI and weapons are straight out of Doom. However, the game is running on a true 3D engine, with 3D enemies, not sprites. It’s inspired by the full 3D engine pioneered by Quake, hence the designation.

Files are available for those wishing to try it out at home. We do see a fair bit of the ZX Spectrum around these parts. Video after the break.

Will An 8088 Run DOOM? Now, Yes It Will!

The question on everyone’s lips when a new piece of hardware comes out is this: Will it run DOOM? Many pieces of modern hardware have been coaxed into playing id Software’s 1993 classic, but there have always been some older machines that just didn’t have the power to do it. One of them has now been conquered though, and it’s a doozy. [Frenkel]’s Doom8088, as its name suggests, is a port of the game for the original PC and AT.

As can be seen in this gameplay video, it’s not always the slickest of gaming experiences. But it works, so the question is, how on earth can a machine that was below the spec of the original, run this game? The answer comes in it being a port of GBADoom for the Game Boy Advance, a platform with less memory than a DOS PC. It still relies on extensive hard disk access for every frame though, which leaves it snail-like.

We set out to install it ourselves on one of the web based PC emulators, but fell over on the size of the required Watcom installation. If any of you have the real thing lying around though, we’d love to hear about how the game performed in the comments.

We’ve shown you so many ports of DOOM over the years to have lost count. One of our favourite recent ones uses an extremely unconventional but very retro display.

Running DOOM In A Keycap Takes Careful Work

Shoehorning DOOM into different hardware is a classic hacker’s exercise, and [TheKeebProject] managed to squeeze the 1993 classic into a custom keycap with the help of a Raspberry Pi RP2040, a custom PCB, and a clear resin enclosure. It even has a speaker for sound!

All processing is done inside the keycap, which is a clever feat. There is a USB connection, but it’s only for power and keyboard controls, so it’s completely playable without needing a whole lot of external support. The custom PCB and code are based off an earlier RP2040 DOOM project, and [TheKeebProject] has certainly made it their own by managing to get everything so tightly integrated. There’s a quick video mashup embedded below. There’s still a bit of work to do, but the code and design files are all on GitHub should you wish for a closer look.

Making DOOM physically smaller is a good challenge, but we’d like to remind fans that we’ve also seen DOOM shrink in terms of power consumption, all the way down to 1 mW.

DOOM On IPhone OS, On Android

So you want to play some games from the early days of 32-bit iPhone OS that no longer run on recent OS versions? [Hikari-no-yume] wrote a sweet high-level emulator, touchHLE, to do so on modern iOS phones. But maybe you don’t have an iPhone? [Ciciplusplus] has your back. He ported the iPhone OS emulator, written in Rust, to Android, and then ported a version of DOOM that runs on iPhone OS to go with it.

[Ciciplusplus] also made a video (embedded below) where he documented the trials and tribulations of porting Rust code to the Android platform – an intensely Java environment. It doesn’t sound like it was at all trivial. Of course, this couldn’t have been accomplished without [Hikari-no-yume]’s original work on touchHLE, which was made essentially to fulfill [Hikari-no-yume]’s long-time obsession with the game Super Monkey Ball.

So for now, touchHLE can boast the ability to run a few old 32-bit games on Android and desktop operating systems. What other games from the first years of gaming on smart phones (and iPods) do you need to see ported? Get involved in the project if you’ve got an itch you need scratched.
