Details of Mario Kart 64’s Catchup AI

It’s information I’d much rather see in text, and I find the video a bit annoying from a construction standpoint (the speaker has a bad case of Youtube Voice), but it’s really interesting information regardless. This video from Abyssoft contains a deep explanation of MK64’s opponent driving algorithm, and explains that the game selects two rivals for your character on each cup, and that opposing drivers pick one of three paths through the course, and can clip right through walls if needed to continue driving around the circuit.

Roguelike Celebration Talks Start Tomorrow!

Ah, it crept up on me, so let me remind everyone that Roguelike Celebration begins today, although until tomorrow it just means they’re opening their social space for awhile. Nicole Carpenter at Polygon wrote a short piece about this year’s conference.

Frightened Ghosts in Pac-Man: Where Do They Go?

Retro Game Mechanics Explained generally does interesting videos, I find. The details on how the ghosts (monsters) in Pac-Man behave when dangerous are fairly well understood now, thanks to the work of Jamey Pittman in writing The Pac-Man Dossier. RGMEx did a summary video of that work three years ago.

The question of how vulnerable ghosts move, after Pac-Man has eaten a Power Pellet (Energizer), isn’t covered in as much detail. It’s still as accurate as the rest of the information in the document, but its implications are left for the reader to explore. Well, RGMEx has explored it.

Vulnerable ghosts move pseudo-randomly, through an interesting process. The game has a RNG (random number generator) that’s reset at the start of every level, that cycles through a period of 8,192 values. Vulnerable ghost movement is the only thing in the game that it’s used for, but it isn’t applied directly. Instead, it’s used as a pointer into the game’s own code, and the value of the address it finds is used to determine how the ghost moves.

A result of this is that not all directions are chosen equally. But further, and more importantly, if the direction chosen isn’t available, the ghost tries the next direction in a clockwise order. If that one’s not possible, it tries the next, until it finds one that works.

These two facts combine to give a definite bias to the directions that frightened ghosts move. Retro Game Mechanics Explained then ran the numbers and figured out where scared ghosts tend to go. It’s interesting, even slightly useful, information.

Dall-E Sucks At Drawing Most Classic Video Game Characters

I had originally scheduled a post on this for a couple of weeks ago, but WordPress gained what I will euphemistically call a personality at that time, and the post developed a “critical error” whenever I tried to edit or view it. I kept pushing it back in the hopes of being able to figure out what was the trouble, but the trouble refused to be be figured out. So eventually I just remade the post.

Whether it’s intentional or not, if you ask Dall-E to depict a number of classic video game characters or elements, it’ll show itself to be surprisingly clueless. Here’s what I got from it:

News 2/16/23: Switch Online, Google Share Prices, MS v Sony, Toaplan

“We scour the Earth web for indie, retro, and niche gaming news so you don’t have to, drebnar!” – your faithful reporter

Welcome shlorbs and foobs to our mostly-weekly text-based internet news program! I hope you enjoyed our techno/bicycle horn fusion theme song! It’s the number one chart-topper on my homeworld, but admittedly my species doesn’t have ears. Images includes in this post are ultimately from Mobygames.

Emily Olson at NPR (swanky!): Google’s shares dropped by $100… (holds paper in front of eyes, reads twice to make sure I see it right)… billion after a disastrous AI demonstration. As a wise cartoon butler once said, “You people have too much money!” I guess we see where everyone’s looking for the next unsupportable tech bubble now that crypto’s in what I understand humans call “the crapper!” I never understood that saying personally. It isn’t the thing that craps!

Liam Doolan at Nintendo Life tells us that the game lineup on the Japanese version of the new Game Boy game collection on Nintendo Switch Online is different than the Western lineup. Alone in the Dark: The New Nightmare replaces video mahjongg player Yakuman. Interestingly the article tells us that Japan-only classic For The Frog The Bell Tolls is coming eventually, although it doesn’t say if it’ll see U.S. release, let alone if it’ll come out on my planet, drebnar!

I’ll admit, Kirby’s Dream Land is pretty nice.
Just look at the smile on that bomb-throwing Poppy Bros. Sr. That’s not the look of a sane person.

Also, Andrew Webster of The Verge says that the addition of the Game Boy games make Nintendo Switch Online the ultimate retro subscription. I mean it’s pretty good, but how was it that Gameboy titles were what pushed it over the line?

Matt Bassil of Wargamer brings us the surprising news that Bank of America thinks that Hasbro is harming its business by over-monetizing Dungeons & Dragons and Magic: The Gathering. When a bank thinks you’re too money-grubbing you might want to sit down with some hot tea and reflect on your life.

Kotaku. Luke Plunkett. Sony claims before court that Microsoft’s request for documentation goes so far that it’s “obvious” harassment. I mean I am at a point in my blobular life that I don’t see anyone representing a corporation as saying a single syllable that isn’t mathematically calculated to four decimal places to improve their balance sheet, so who the hell knows if it’s true. Maybe it is? I am staying neutral in this fight. Acids and bases hurt my cell wall.

Metroid Prime

Oli Welsh of Polygon really likes the HD remake of Metroid Prime that Nintendo put on sale a few days ago, noting that it includes the pointing interface improvements introduced with the Wii rerelease.

Will Shanklin of Engadget tells us that a “Minecraft mad scientist” has recreated The Legend of Zelda in Minecraft, and in true mad scientist fashion is holding the work hostage, refusing to release it unless a video demonstrating it hits 5,000 Youtube likes. The article said it was at 500 likes; at our own press time it was up to 4.5K, so by the time you read this it should have enough. I will pass it along to Editorial as possible blog fodder (“blodder”) for Set Side B!

Ron Amadeo brings us the news that with the switch to monthly updates of Android 14, Google will begin just blocking apps on it made for versions of Android before 6. The reason given is security, but bah to that, old software and its preservation simply isn’t a priority for megacompanies like Google. Does anyone remember the days when it seemed like they might be a different kind of tech company? Me neither.

Nicole Clark at Polygon says Okami is the best Zelda-like. Sal Romano at Gematsu reveals that M2 is planning a collection of Toaplan shooters, including the infamous Zero Wing, the game whose U.S. translation brought us the “All Your Base” meme a 100 billion years ago. And Justin Carter at Game Developer reveals that Double Fine has made a documentary about the making of Psychonauts 2. Drebs out!

News 12/1/22: DABLOONS

“We scour the Earth web for indie, retro, and niche gaming news so you don’t have to, drebnar!” – your faithful reporter

Quite a bit to get through today! Pull up a florb and moop for a bit!

Luke Plunkett at Kotaku informs us of Nintendo pulling support from the third-party tournament Smash World Tour, leaving them in a gigantic financial hole. This will severely harm tournaments’ willingness to trust Nintendo in the future, and the esports scene around future Nintendo products. Nintendo’s response at the end is especially frustrating, claiming they did not request any events be cancelled while still denying SWT a license, forcing them to cancel anyway.

Benj Edwards at Ars Technica: an AI from Nvidia can play Minecraft now, performing tasks based on text prompts. Congrats, you’ve invented a 10-year-old!

After our initial post, I’ve purposely been trying not to talk up the Super Mario Bros. movie, but I do think this post from Ryan Leson at IGN is of interest, about Shigeru Miyamoto noting that Donkey Kong’s been a bit redesigned for the movie, still recognizably the Rare-made version of the character, but with some adjustments to more resemble the original version.

Here’s Rich Stanton at PC Gamer on the effort to preserve a Ridge Racer Full Scale, a version of the arcade game that featured an actual car chassis the player would sit it, had triple ultra-wide display, and cost operators $250,000. Very few were sold, and it’s possible only one survives, which was in Blackpool. After an arcade museum sought to purchase it, but refused when they learned of damage to the frame, it was thought lost, but although the physical structure of the unit has not been salvageable, the car portion and the hardware have been saved, and its code dumped. More can be read at Arcade Blogger.

Yep! I’m old.

Richael Watts at Rock Paper Shotgun has a piece up on Dabloontok, an RPG-ish thing a bunch of people are doing on TikTok, involving cat videos trading an imaginary currency called “dabloons.” This isn’t imaginary in the sense of crptocurrency, or indeed all money when you think about it; this is really imaginary. How many you have is completely on the honor system. Participants use it to “trade” with these cats, and they can also be “stolen” by them. The whole thing seems pretty silly overall, but it’s entertaining to learn about!

And at Engadget, I. Bonifacic remarks upon Pong turning 50 years old. Yeah, that number isn’t getting any smaller. It’s a useful retrospective, although I take issue with them saying that without Pong Nintendo would not exist. Nintendo is over a century old, originally making playing cards. What is more likely is they wouldn’t exist as we know them today-they may not have gotten into video games at all. (By the way, they make traditional Japanese game playing equipment too, like go boards!)

News 11/9/22: Lego Zelda, AI Art, EA Software Patent

“We scour the Earth web for indie, retro, and niche gaming news so you don’t have to, drebnar!” – your faithful reporter

Lego is banning new Ideas projects based on The Legend of Zelda, according to Chris Wharfe at Brick Fanatics. The reasoning given is a bit vague. It could either be because Lego is working on their own Zelda sets (and they already have a working relationship with Nintendo, making the popular Super Mario sets), or it could be that the rights to Zelda models were sold to someone else. Either way, it may mean we get Zelda models through some company eventually.

A pretty good Link model from Lego Ideas! From its project page.

PC Gamer, Andy Chalk: Final Fantasy XVI’s using excuses to not have Black characters. Specifically, by claiming the game’s world is based on medieval Europe, despite Black people existing there. Grumble, grumble!

Old school blogger Mark Frauenfelder of good ol’ Boing Boing mentions illustrator Hollie Mengert discovered her work was used without her permission to make AI-generated work, and the model that utilized her work released as open source by MysteryInc152. It links to an original article by Andy Baio at Waxy. Someone explain to me how AI-generated work isn’t legally a derivative work based on every work it’s trained on? That seems like it’s just obvious.

From Andy Baio’s article-the left is Hollie Mengert’s work, the right, the output of the AI model trained from it.

Rich Stanton at PC Gamer writes that EA’s been granted a patent on game controls that change based on how well the player does. Software patents are bad on principle, that is a horse that I will always flog despite this awful situation having existed for literally decades now, but getting past that, for now. This seems at first like just another version of adaptive difficulty, which is also something that seems like it’s kind of a problem when it happens without notifying the player or giving them a say in it. I know I know, “Kent Drebnar, get with the 21st Century.” Maybe I’ve been hanging out with the Gripe Monster too much lately. The article goes back into the history of these kinds of effort, going all the way back to Compile’s Zanac, although I would argue that’s not so much adaptive difficulty as a system that the player can strategize to manipulate. Zanac is terrific, by the way.

Bryan at Nintendo Everything mentions that Sega is hiring a Sonic “loremaster,” presumably someone who knows the history of the many forms of the character. Said role will assist in creating new content and characters in the Sonic universe. Sounds like a tall order given the many varied and contradictory versions of the property there’s been, but I’m sure there are people out there who are up to it. Good luck, whoever they pick!

News 7/12/22: Yu-Gi-Market Contraction, Oh!

“We scour the Earth web for indie, retro, and niche gaming news so you don’t have to, drebnar!” – your faithful reporter

It’s a rare day that we get to link to the Washington Post, in this case a piece by Michael Cavna on the death of Yu-Gu-Oh! creator, mangaka Kazuki Takahashi. Hey there Michael! Bet you never thought your work would be linked by a single-celled pixel-art organism! Can you ask them to do something about their ludicrous paywall drebnar? Yu-Gi-Oh! is only tangentially part of our purview here but there have been enough video games from that series that we can probably make room for it under Retro, plus it’s published by Konami. One of my favorite facts is that the card game includes several cards that officially refer to the Gradius series, including cards of the Vic Viper and Big Core.

Elliot Williams at Hackaday challenges us: You think you know how Mario Kart works? I think so? You supply electric potential through a wire to a console loaded with some game software, which sends signals to a video screen, and you use a wired controller to interact with it. Yes, I win! His article just links to a video (see above) about how the AI drivers work. This subject has been thought of so much that there’s a patent on such drivers granted to Lyle Rains for his work back in the early days of Atari, in 1979! That it took 20 years for that to expire is a blight on the history of game programming, drebnar!

PC Gamer’s Rich Stanton tells us that Yuji Naka is still angry at Square Enix for removing him from the Balan Wonderworld project. He accurately notes that the degree of acrimony from Naka about this is unprecedented-Naka is pissed and doesn’t care who knows it. The article suggests listening to both sides here. Here at Set Side B we admit, we tend to take the word of developers over those of gigantic corporations, especially when the developer is someone of Yuji Freaking Naka’s standing! We may be wrong, and if the word comes out that we are we’ll cheerfully admit to it, but it is easy for me to believe, in Naka’s words, that Square Enix “doesn’t care about games.”

Zack Zaiezen at Kotaku writes that Take Two is going after another Grand Theft Auto modder. Boo! Hiss! News like that fills up my angry sac!

It’s a good day for linking to non-gaming sites! At CNBC, Ryan Brownie warns of a coming contraction of the games industry, partly due to it coming down off the boost caused by the pandemic, and also from bottlenecks produced by Russia’s invasion of Ukraine.
