As the saying goes: if it has a processor and a display, it can run DOOM. The corollary here is that if some software displays things, someone will figure out a way to make it render the iconic shooter. Case in point KiDoom by [Mike Ayles], which happily renders DOOM in KiCad at a sedate 10 to 25 frames per second as you blast away at your PCB routing demons.

Obviously, the game isn’t running directly in KiCad, but it does use the doomgeneric DOOM engine in a separate process, with KiCad’s PCB editor handling the rendering. As noted by [Mike], he could have used a Python version of DOOM to target KiCad’s Python API, but that’s left as an exercise for the reader.

Rather than having the engine render directly to a display, [Mike] wrote code to extract the position of sprites and wall segments, which is then sent to KiCad via its Python interface, updating the view and refreshing the ‘PCB’. Controls are as usual, though you’ll be looking at QFP-64 package footprints for enemies, SOIC-8 for decorations and SOT-23-3 packages for health, ammo and keys.

If you’re itching to give it a try, the GitHub project can be found right here. Maybe it’ll bring some relief after a particularly frustrating PCB routing session.

When people talk about the lack of a DOOM being the doom Commodore home computers, they aren’t talking about the C64, which was deep into obsolescence when demon-slaying suddenly became the minimal requirement for all computing devices. That didn’t stop [Kamil Wolnikowski] and [Piotr Kózka] from hacking together Grey a ray-cast first-person shooter for the Commodore 64.

Grey bares more than a passing resemblance to id-software’s most-ported project. It apparently runs at 16 frames per second on a vanilla C64 — no super CPU required. The secret to the speedy game play is the engine’s clever use of the system’s color mapping functionality: updating color maps is faster than redrawing the screen. Yeah, that makes for rather “blockier” graphics than DOOM, but this is running on a Commodore 64, not a 386 with 4 MB of RAM. Allowances must be made. Come to think of it, we don’t recall DOOM running this smooth on the minimum required hardware — check out the demo video below and let us know what you think.

The four-level demo currently available is about 175 kB, which certainly seems within the realms of possibility for disk games using the trusty 1541. Of course nowadays we do have easier ways to get games onto our vintage computers.

If you’re thinking about Commodore’s other home computer, it did eventually get a DOOM-clone.

Thanks to [Stephen Walters] for the tip.

On Monday, veteran game developer Rebecca Ann Heineman died in Rockwall, Texas, at age 62 after a battle with adenocarcinoma. Apogee founder Scott Miller first shared the news publicly on social media, and her son William confirmed her death with Ars Technica. Heineman’s GoFundMe page, which displayed a final message she had posted about entering palliative care, will now help her family with funeral costs.

Rebecca “Burger Becky” Heineman was born in October 1963 and grew up in Whittier, California. She first gained national recognition in 1980 when she won the national Atari 2600 Space Invaders championship in New York at age 16, becoming the first formally recognized US video game champion. That victory launched a career spanning more than four decades and 67 credited games, according to MobyGames.

Among many achievements in her life, Heineman was perhaps best known for co-founding Interplay Productions with Brian Fargo, Jay Patel, and Troy Worrell in 1983. The company created franchises like Wasteland, Fallout, and Baldur’s Gate. At Interplay, Heineman designed The Bard’s Tale III: Thief of Fate and Dragon Wars while also programming ports of classics like Wolfenstein 3D and Battle Chess.
