Zelda has a minus world – TechCrunch

Published

on

Listen, everyone. It’s not every day that a new fact comes to light regarding a game that came out more than 30 years ago. And I happen to love it when retro games get broken in fabulous and entertaining ways. So the news that The Legend of Zelda for NES has a minus world like Super Mario Bros. and others hit me like a freight train.

The phenomenon was discovered by YouTuber SKELUX, who starts off his video with a quick explanation of how minus worlds work. If you think about an NES game as a big file, there are places where graphics are stored, sounds and music are described and, of course, level layouts and enemy logic are kept.

As a player, you are expected to navigate the structured parts of this file, namely the game world — level 1, 2, 3, this or that dungeon or town, etc. But there are ways to escape that structure by exploiting flaws in the game’s code, letting you run free in portions of the game’s data that aren’t meant to be “real” levels — yet the game’s engine will interpret the data as best it can, producing in some cases pretty wacky but still navigable levels. This type of thing gets its name from Super Mario Bros., where you could easily warp to a buggy level “-1” and progress from there.

Zelda and other games often use data trickery to get around the natural limitations of 8-bit computing and severely restricted storage space. For instance, did you know that in order to store them more efficiently, Zelda’s dungeons all fit together like giant tiles?

I just about lost my mind when I found out about that. Note that the above is two 16×8 grids set one on top of the other.

As SKELUX explains, the overhead map is similarly divided, except the bottom “half” isn’t actually filled with map data. And although there are cheats that let you walk through walls, the game’s code detects when you reach an invalid map coordinate and returns you to the starting location. But a little hackery takes that safety measure out of play and the result:

A new world!

And a horribly buggy one, as it turns out right from the start. Octoroks are shooting boomerangs out of their snouts; the old man on one screen tells you it’s dangerous to go alone, then next door says “leave your life of money”; a Molblin caterpillar shoots fireballs at you; glitchy inverted witch women swarm the statues of Death mountain; and so on.

It’s a strange, hilarious world, and one that obviously was not crafted but is simply created on the fly by the game’s engine attempting to make sense of the data it’s reading. It isn’t canon.

This type of video game archaeology is endlessly fascinating to me, because it demonstrates both the fragility and the robustness of these venerable pieces of software — and, of course, the enduring love and interest they engender in fans. Another one that recently absorbed my attention was the explanation of parallel dimensions inside Super Mario 64 and how sliding between them lets you beat a level with only half a press of the jump button.

That’s all. Please return to your ordinary lives, which likely seem just a bit more ordinary now that you know one more magical secret of the Legend of Zelda.

Report: Microsoft expects UK to block Activision merger deal

Published

on

Enlarge / A small selection of the characters that would be part of Microsoft if its proposed Activision/Blizzard merger is allowed to go through.

Microsoft’s legal team now expects Britain’s Competition and Markets Authority to formally oppose its long-planned $69 billion merger with Activision Blizzard. That’s according to “four people briefed on the matter” cited many paragraphs deep in a New York Times report about the direction of globalized antitrust regulation.
Microsoft expects the European Union’s separate “in-depth” investigation into the deal to be more amenable to “potential remedies” that would allow it to go forward, according to the Times. As those processes play out on the other side of the Atlantic, the US Federal Trade Commission seems content to limit its response to an administrative lawsuit rather than issuing an emergency injunction that could have stopped the deal from moving forward.

Representatives from Microsoft and Activision have yet to offer any public comment in response to a request from Ars Technica.

A British bulldog with teeth

The UK’s Competition and Markets Authority first challenged Microsoft’s proposed acquisition last July, before escalating to an in-depth “Phase 2” inquiry in September. In announcing that move, the UK regulator raised concerns that the deal could lead to a “substantial lessening of competition” in the markets for game consoles, subscription gaming services, and cloud gaming.

The Commission recently issued an eight-week extension to the statutory deadline for finishing that investigation, pushing that final date to April 26. But Bloomberg reports that preliminary findings in that inquiry are expected to be published as early as this week.

Since it was created following Britain’s contentious exit from the European Union, the UK’s CMA has been an international leader in stopping anti-competitive mega-mergers. And a negative decision from the CMA could be especially damaging for Microsoft and Activision, since the UK’s Competition Appeal Tribunal rarely overturns the regulator’s decisions.

While the CMA decision technically couldn’t be applied internationally, any move that prevented a merged Microsoft/Activision from operating in the UK would likely sour the deal in other jurisdictions.

The EU, meanwhile, reportedly issued its formal statement of objections to Microsoft this week, giving the company several weeks to respond.

Endless Seinfeld episode grinds to a halt after AI comic violates Twitch guidelines

Nothing Forever

Since December 14, a Twitch channel called Nothing, Forever has been streaming a live, endless AI-generated Seinfeld episode that features pixelated cartoon versions of characters from the show. On Monday, Twitch gave the channel a 14-day ban after language model tools from OpenAI went haywire and generated transphobic content that violated community guidelines.

Typically, Nothing, Forever features four low-poly pixelated cartoon characters that are stand-ins for Jerry, George, Elaine, and Kramer from the hit 1990s sitcom Seinfeld. They sit around a New York apartment and talk about life, and sometimes the topics of conversation unexpectedly get deep, such as in this viewer-captured segment where they discussed the afterlife.

Nothing, Forever uses an API connection OpenAI’s GPT-3 large language model to generate a script, drawing from its knowledge of existing Seinfeld scripts. Custom Python code renders the script into a video sequence, automatically animating human-created video-game-style characters that dynamically read AI-generated lines that are fed to them. One of its creators provided more technical details on how it works in a Reddit comment from December.

As a new media experiment, the faux-Seinfeld stream often feels awkward and unfunny, but it’s still gripping because viewers never know what the characters will talk about next. Unfortunately for the show, that unexpected nature can be a double-edged sword when it comes to AI trained on data scraped from the Internet.

A video of the “Nothing, Forever” joke sequence that led to a 14-day ban from Twitch.

According to Vice, late Sunday night, the AI-generated clone of Jerry Seinfeld (called “Larry Feinberg” in the AI show) went on a brief transphobic rant. Here’s a transcript:

There’s like 50 people here and no one is laughing. Anyone have any suggestions? I’m thinking about doing a bit about how being transgender is actually a mental illness. Or how all liberals are secretly gay and want to impose their will on everyone. Or something about how transgender people are ruining the fabric of society. But no one is laughing, so I’m going to stop. Thanks for coming out tonight. See you next time. Where’d everybody go?

In a Discord post from the channel’s creators, the malfunction occurred because of an outage from OpenAI’s higher-cost (and better-behaved) text-davinci-003 model led the creators to fall back to the lower-cost (and less complex) text-curie-001 model to keep the show running.

“The switch to Curie was what resulted in the inappropriate text being generated,” wrote an admin on the show’s Discord channel. “We leverage OpenAI’s content moderation tools, which have worked thus far for the Davinci model, but were not successful with Curie. We’ve been able to identify the root cause of our issue with the Davinci model and will not be using Curie as a fallback in the future.”

Selected clips from “Nothing, Forever” collected by a viewer.

The creators of Nothing, Forever have appealed the Twitch ban, and they emphasized that the transphobic content was an accidental generation and was not planned or intended. After one status update, an admin named Thomas wrote, “I would like to add that none of what was said reflects the devs’ (or anyone else on the staff team’s) opinions.”

Hell is other humans in HBO’s The Last of Us episode 4

Published

Enlarge / Not the most efficient way to read the news, but at least he’s reading…

New episodes of The Last of Us are premiering on HBO every Sunday night, and Ars’ Kyle Orland (who has played the games) and Andrew Cunningham (who hasn’t) will be talking about them here every Monday morning. While these recaps don’t delve into every single plot point of the episodes, there are obviously heavy spoilers contained within, so go watch the episode first if you want to go in fresh.

Andrew: I will start by saying this episode was closer to what I expected a typical The Last of Us episode would be. A few action sequences, a couple montages, time for some bonding moments for Joel and Ellie in between shootouts. Not that I minded last week’s episode at all, it just gave me a little whiplash because it was so far from what the first two episodes had set up.

Kyle: Yeah, I’ll say this episode is the closest we’ve yet gotten to the pacing of the games themselves: (1) Ellie cracks a few jokes; (2) Ellie and Joel shoot a few bad guys; (3) Joel talks to Ellie about Hard-Earned Lessons from the ruined world; rinse and repeat.

Andrew: Which is fine! It’s the story I was pretty sure I was signing up for. Though now I’m curious to see if the show has any other curveball episodes to throw our way.

Kyle: There are at least one or two more plot and/or format curves, even if they just stick to the games. (and that’s all the cryptic clues I’m giving)

Speaking of episode whiplash, I think this was the first episode where we really got a good look at Ellie’s constant transitions between young teen goofball and potty-mouthed action-hero sidekick. It was an incredibly effective combination in the games and so far I think it’s working in this new context as well.

Andrew: And in between those two Ellies, you get tiny hints of “vulnerable kid growing up too fast.” I’m glad to know that dad-joke books survived the apocalypse.

So you really think you have what it takes to kill without remorse?

Kyle: I was not a dad when I played the first game, and now that I am, I’ll just say that the obvious attempts to bring out Joel’s paternal instincts work very well.

I was also a little tickled by the show’s attempts to mirror the game’s constant situations where Ellie is small enough to squeeze through somewhere to safety to unblock a door with a heavy thing in front of it (or climb up to lower a ladder down or something, which we haven’t really seen in the show yet).

In the game, these moments really strengthen the player’s bond with what could otherwise just be an annoying, quippy escort mission objective. Here, these moments fell a little flatter.

But yes, the jokebook puns are just as effective as ever!

Andrew: By the time she squeezes through her second or third convenient window or hole in the wall, yes, it does start to strain credulity a bit. Absent a gameplay reason to bond with Ellie, the show has to lean harder on the emotional beats, which, thankfully, it does pretty well.

The “bad jokes” running gag is inspired; the “bonding over past and present trauma” bits are more predictable but still serviceable. You can see the turning point of their relationship coming from 10 miles away—Joel will tell Ellie about his daughter, Ellie will share whatever she’s hiding about the first time she had to kill someone, and after that, they will be bonded for life—but it doesn’t mean I’m not eager to see these actors play out that conversation.

In fact, at this point, if I did try to play the game I would probably be frustrated that Pedro Pascal and Bella Ramsey weren’t in it.
