What’s So Random About Ms. Pac-Man

I’m not going to say that famously Ms. Pac-Man is a more random game than Pac-Man, because who really knows things like that who isn’t a hardcore gamenerd. But among hardcore game nerds, it’s common knowledge. (If you didn’t know, A. congrats on your coolness, and B. sorry to now destroy your coolness.) Here a video about how randomness works in that game, from Retro Game Mechanics Explained (21 minutes):

Pac-Man is a game that is vulnerable to patterns: if you do exactly the same thing each time on the same level, the same results will occur. There is one pseudo-random element in Pac-Man though: when vulnerable ghosts reach an intersection, the code picks an arbitrary address from a range of memory addresses, then uses that value to pick a direction to decide which route to take. Two implications of this: vulnerable ghosts are most likely to head left at intersections and least likely to go up, and if any byte in that range changes the behavior of the game slightly changes too, even if it’s not an executable byte. Patterns still work in Pac-Man, despite this pseudo-random function, because the seed is reset at the start of every level, so if you do exactly the same thing, vulnerable ghosts will still have the same information fed to their movement routines.

Ms. Pac-Man has other sources of randomness: the ghosts, in Scatter mode, use a different source of pseudo-randomness to decide where to go, one that isn’t so easy to manipulate; and which fruit appears and which of four predefined routes (three for one of the mazes) it’ll take through the board.

Ms. Pac-Man doesn’t have its ghosts scatter periodically through the level like they do in Pac-Man. They only scatter at the start of the board. It’s not much randomness, but it’s enough to upset rote pattern creation, since each ghost has the opportunity to make several decisions of which path to take during that period. The way the randomness is handled is interest itself. The ghosts pick one of the corners of the board, much like they would in original Pac-Man, but randomly, when making their choice of target to home in on.

So there! Now you can amaze your friends, if it were 40 years ago and your friends were then able to be impressed by your knowledge of Ms. Pac-Man! You’re retroactively welcome!

News 8/12/2022: Re-Volt, Pac-Movie, MOS7600

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

Graham Smith at Rock Paper Shotgun tells about the return of Re-Volt, an RC Car racing game from the Dreamcast age that many regarded as fairly lackluster, but has nonetheless gathered a strong fanbase. It’s for sale again on Steam and GOG. While the game itself isn’t terrific as it is, fan-made mods that improve it require ownership of the original to function.

At GamesRadar (warning: will harass you to subscribe to their newsletter), Dustin Bailey (which may be a fun pseudonym) lets us know that the Coconut Mall reprise track from the DLC of Mario Kart 8 has been “improved,” in that the cars in the parking lot at the end of it now drive around getting in your way like they did back in the Wii version, and in fact are now even more annoying, doing pointless doughnuts in the lot just to piss you off. And yet, the drivers are Shy Guys, not the system Miis that drove the cars in the original, which in my bulbous eyes is still a downgrade.

Jesse Belinsky at The Verge contributes a personal essay about how the Animal Crossing series helped them explore their gender. They especially note how the pandemic gave them the push they needed, an event which will be remembered for years to come as a pivotal moment in time, I think at least.

Coming soon, just in time for… 2023?! They might have missed this property’s best-by date.

In sillier news, at the Hollywood Reporter, Mia Galuppo tells us that Bandai Namco is trying to get a Pac-Man movie made. Pac-Man’s relationship with media has been a strange journey. In Japan it originally didn’t do especially well, but in the U.S. it quickly set arcade cabinet sales records, partly due to the stewardship and marketing acumen of U.S. licensee Bally-Midway. They commissioned several sequels that were unauthorized by original creator Namco, most of which have been stricken from the records, except, for a time, Ms. Pac-Man, created by GCC as a hack of the original game that would go on to eventually surpass it in lifetime sales. Namco would in turn adapt several aspects of the Pac-Man expanded universe for their own use, notably Ms. Pac and aspects of the first Pac-Man TV show, a pretty dumb cartoon made by Hanna-Barbera back in the period where they’d adapt anything for a buck. Namco made Pac-Land, an important early scrolling platformer, using the characters, music, and art style from that cartoon. In recent years rights issues have caused Bandai-Namco to reject Ms. Pac-Man too, creating a rights-unencumbered replacement character called “Pac-Mom,” which presumably will feature in this movie. All of this is just to demonstrate to you how incredibly twisted and fraught Pac-media has become, and I haven’t even gotten into the second TV show, Pac-Man and the Ghostly Adventures, which I’d rather not discuss. I will note, however, that because of Pac-Man’s inclusion as a character in Smash Bros. 4 and Ultimate, the first Pac-Man cartoon show in some small way lives on in Smash Bros’ Pac-Land stage.

Hamish Hector at TechRadar (that’s a different site from GamesRadar, right?) writes that there’s never been a worse time to buy an Oculus Quest 2. Considering that dumps more money into the hated trough of Zuckerberg, I can’t think that there’s ever been a good time.

Jenny List at Hack-A-Day points to a long and interesting post by Cameron Kaiser on good ol’ Blogger blog Old Vintage Computing about MOS Technology’s early entries into the Pong system-on-a-chip market, the MOS 7600 and 7601, which were programmable, meaning, they could run code, and systems that used them. It makes for fascinating reading to my gelatinous brain.

And at PC Gamer, Christopher Livingston relates how the developers of survival MMO Last Oasis decided their genre “sucks,” and reworked it to be PvE instead of PvP.

News 7/4/2022: Gilbert’s Sonic Pac-Mom

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

Jay Peters at The Verge reports that, sadly, personal attacks from griefers have caused Ron Gilbert to stop posting updates on the development of his upcoming Monkey Island game. Booo! Don’t be a Gripe Monster, friends!

On NintendoLife, Damien McFerran mentions an piece in the next issue of pay fanzine Lock-On by Undertale and Deltarune creator Toby Fox, about the impact of the Japanese series Mother, known in the US as Earthbound.

Destructoid’s Chris Moyse mentions the remake of Pac-Man World mentioned at Nintendo’s indie-focused Direct has Pac-Mom instead of Ms. Pac-Man, pushing her further down the memory hole. The issue seems to be a rights issue around the character, who was not created by Namco but instead by classic indie arcade designer GCC, who has licensed her exclusively to AtGames.

It was a few days ago, but at Kotaku Jeremy Winslow posted about Simon Thomley, a.k.a. “Stealth,” of Sonic Mania developer Headcannon, about how he has complained that their work on Sonic Origins was done under time crunch, and they were not allowed to debug their work before release, and even that integration with the final product introduced new bugs they were not responsible for.

Greetings, humans! Here is the gaming news I could glean from decrypting your internet broadcasts from my flying saucer floating above your atmosphere!

Jordan Devore, Destructoid: Rogue Legacy 2 Drops Vertigo From Its Traits List. You see, each character you play in that game is part of a lineage of characters, and they have semi-random traits. One of those traits flipped the screen upside-down during play. Or it did. Now it’s not in the game anymore!

Oisin Kunhke, Gamebyte tells us about a word-in-progress Breath of the Wild Randomizer mod!

Brad Linder of Liliputing notes of a new version of a three-key keyboard made by Stack Overflow.

Wololo (?) of Wololo (??) tells us that homebrew fans are reviving Playstation Home!

Andrew Cunningham at Ars Technica lets us know that Nvidia is facing scrutiny from the FCC for inaccurately representing how cryptocurrency mining boosted the sales of their graphics hardware.

Sam Medley of NotebookCheck tells of AltStore, a sneaky way around Apple’s App Store for distributing software they’d rather you not use. I hesitate to speculate on how long this loophole will last, but I’m no fan of hardware lockouts and use limitations, so it’s nice while it lasts!

More news from the orchard. MacRumors talks with Feral about porting games to Apple’s new M1 hardware and the difficulties it has faced with their graphics.

Always awesome Kyle Orland at Ars Technica has an article with a headline too fun to paraphrase: Eve Online fans literally cheer Microsoft Excel features at annual Fanfest.

Trent Cannon of Nintendo Life reviews Prinny Presents: NIS Classics Volume 2 for Switch.

Alex Donaldson at VG247 warns us that Sonic Origins probably won’t have Sonic 3‘s original soundtrack, due to rights issues related to Michael Jackson’s involvement with the project. Sega has been hampered with music rights across several games, including the soundtrack for some ports of Crazy Taxi.
