PCNY Chronology Research (Sequencing)

“Sequencing”, what on earth is that? Well you see, certain PCNY Pokémon “go together”. Not in the sense of evolutionary lines or boudoir compatibility, but in that they were distributed from one of the PC New York’s four “Gotta Catch ‘Em All” (GCEA) stations during a particular, retraceable timeframe. Through sequencing, we try and work out what was distributed when.

Think of it like this. Your workplace probably has a coffeemaker, right? That’s our GCEA station. During, say, the fourth week of October 2003 (Ghost Week), it was able to randomly dispense four different flavours of coffee (four Pokémon). Sometime during that week, a hypothetical Joe filled up a whole tray with back-to-back coffees. Meryl did the same, as did Harry. Now, the magic of the sequencing technique is that by parsing coffee grounds scraps of Pokémon data, we can learn how many minutes, hours or even days apart Joe, Meryl and Harry used the coffee machine. In turn, this provides us with clues how long a particular combination of flavours (a campaign) was active. It may even, under certain conditions, help us to identify the exact day some 20 years ago that each got their coffees. And if the coffees (Pokémon) handed down by Joe, Meryl and Harry don’t match up at all, this suggests that same flavour combination (campaign) was put back on on another occasion. Neat, huh?

Now, the goal of the sequencing effort is aid in the reconstruction of a fine-grained GCEA campaign timeline. Official sources are scant, and distribution windows derived from memory card campaign data tell us only what was intended, not what transpired. For example, sequencing has borne out that July 2004’s Pokémon Box distribution continued (far) longer than official sources would have it. But I’m getting ahead or myself. To better understand the sequencing tools at our disposal, and why – despite our best efforts – there is yet a divide between the practical outcomes and theoretical potential of sequencing, let’s start by taking a short primer on the inner workings of the friendly-looking GCEA “machines”.

If one were to strip away the custom facade of any of the Center’s four GCEA stations, one would find concealed several pieces of electronics. Most noticeably, each of the stations housed a TV attached to an archetypal turquoise “NR Reader” GameCube DevConsole, which acted as the beating heart that facilitated PCNY distributions. Each GameCube took a disc containing the distribution software as well as two memory cards: one in slot B with system data (“machine information”) required to make the system tick, and one with campaign data in slot A instructing the station what Pokémon to provide during what timeframe. Connected to controller port 4 was a rectangular metal box containing a “cart writer” circuit board that interfaced between the Cubes and players’ copies of Ruby or Sapphire. A cartridge slot poked out from the concealed writer; guests would insert their RS game directly into it and have a Pokémon uploaded straight to their in-game party without further input. The software played back (on the TV) a floating Pokéball animation whenever a station was idling; it switched to classic Pokémon transfer visuals when a Pokémon was being redeemed. A Gameboy Advance hooked up to Gamecube port 3 acted as a superfluous controller and verification handshake for the whole system. Intelligent Systems (of Fire Emblem fame) developed this intricate multi-part setup specifically for the PC New York, initially to service the GSC games of Gen2 and later, in early to mid 2003, modified it for use with Ruby & Sapphire. Words can only describe so much, and for a visual demonstration of the hardware in action, check out Hard4Games’ video on the subject.

Now, each time the cart writer successfully scanned an inserted gamecart, a Pokémon and its slew of unique characteristics like nature, individual values (IVs) and a vitally important hidden identifier called PID were determined pseudo-randomly there and then. The GCEA also conferred two other pieces of Pokémon data critical to constructing a timeline: Original Trainer Name (or OTN) and Trainer ID (TID). Let’s start with the Trainer Name. As is the standard for event Pokémon, the OTN reflected a key piece of information about the distribution, in this case which of four GCEA stations it was derived from: PCNYa, PCNYb, PCNYc, or PCNYd. Or more accurately, which of the four slot B “machine info” memory cards had been plugged into which station. PCNY letter designations were not determined by some immutable station identifier (as was long thought), but dependent entirely on the inserted memory card.

Four stations, four slot B memory cards, so therefore four separate letter designations per campaign, right? Ah. Would that it ’twere so simple! For starters, not all of the GCEA stations actively pushed campaigns all of the time. They could run demos, or simply be shut off. Sources indicate that out of four total booths, at most two operated concurrently during Generation III. This was (initially) not a matter of convenience or power-savings; rather, it had to do with the Center’s floorplan. Located on the second (US) floor, the positioning of the two GCEA stations nearest the front-facing windows created an insurveyable little corner sheltered from watchful eye of PCNY staff and the Center’s security cameras. This was a problem: schoolkids dropped their backpacks there as they explored the Center, only to – on multiple occasions – report theft of personal items. To prevent this from happening, the corner was closed and its two stations shut off. Technical analysis rhymes with this anecdotal insight: both the 2003 and 2004 campaigns blocs only ever had two unique letter designations: PCNYb+PCNYc for 2003, and PCNYc+PCNYd for 2004. Sources further suggest that between December 2003 and March 2004, all four machines were disabled as management lost confidence in their crowd-pleasing usefulness, not to be powered back up until April 2004 – with the intriguing exception of one singular day over Christmas.1When an irate visitor demanded that the GCEA stations be powered up for their kid to redeem Pokémon! No unallocated campaigns that would fill this void are known, with the possible exception of BC (or CD) Dragons.2Source for these insights is former PCNY staffer Aurora.

Also intriguing is how out of four potential PCNY OTN, only three – B, C and D – exist in the wild. The 2003 and 2004 campaign blocs both include PCNYc, yet neither features PCNYa. For years, the absence of OT “PCNYa” fed the popular belief that one of the stations (commonly dubbed “machine A”) had irreparably malfunctioned early in its lifecycle. Yet staff recall no permanent technical GCEA station failures, even the if the two unfortunately situated ones were commonly offline, and overheated NR units needed replacement from time to time.3Source for this latter tidbit is an anonymous employee close to the situation. We now understand that the explanation the missing-in-action PCNYa lies elsewhere: the memory card labelled “A” in fact produced OT PCNYc. The sequencing implication is that we needn’t look for Pokémon marked “PCNYa” because they cannot logically exist, just like campaigns cannot exceed the practical maximum of two unique letter designations (it’s either B & C, or C & D).4Most campaigns have a relative overabundance of Pokémon branded PCNYc compared to B and D. Why this is so is not entirely clear – it may relate to GCEA station positioning.

Right. Now for that second piece of pertinent information the GCEA stations bestowed upon their Pokémon: Trainer IDs (TID). Gen3 event Pokémon TID often point to the starting date of a particular event. The 2004 Tanabata Jirachi for example had a TID of “40707” for July 7, 2004 the first day of the Star Festival on the Gregorian Calendar. Alternatively TIDs might be set to some commemorative number, like “00010” for Pokemon’s Tenth Anniversary “Journey Across America” event series. Unusually, PCNY Pokémon were numbered sequentially. Until a GCEA station was reset, every new Pokémon it produced had its TID incremented by +1 compared to the previous. Meaning, for instance, that the first Pokémon of the day spat out by “machine” B would always be numbered PCNYb 00001, the second PCNYb 00002, the third PCNYb 00003, and so on, up to a theoretical maximum of 65535. By simply surveying the highest TIDs of preserved PCNY Pokémon, we can begin to make guesstimations about the popularity of any given campaign. It’s brilliant.

Seems straightforward, right? Combine OTN with TID and you have your sequence right there! Why bother with technical analysis? Ah. Distro reruns. Reruns? Yes. PC New York staff could reinstate any given campaign at any time by reverting a GameCube’s internal clock to its appropriate programmed distribution window, provided they had the right memory cards on hand, of course. (Reprogramming of which was done at Japan HQ.) Take “Dragon Week”, for example. It’s fair to assume a powerful dragon distribution was popular with visitors to the Center. So did it truly run only once, for a week in early October 2003? Or was it put back on for Christmas, perhaps, as sources tenuously suggest? Did it make a wholly unaccounted for reappearance somewhere in late Spring 2004? Theoretically, anything is possible, limited only by the (unknowable) actions of PCNY staff. As such, even if no machine resets occurred in the midst of a campaign, and no machine hiccups took place that could splice perfectly good Pokémon chains, any campaign can theoretically have multiple distinct sequences. And many do: there isn’t a single distribution bar May 2004’s “Sheep & Wolf” of which we don’t have multiple. Surface-level analysis has difficulty dealing with TID/OTN overlap between sequences, and when used in isolation may cause false positives (Dragon Week’s PCNYc 00021-00026 really look like they ought to fit together, but they don’t!) Similarly, OT/TID “blocs” can often be shuffled to connect up in any number of ways – but which is the correct one? To say nothing of working out the timegaps between them.

Timegaps. What TID/OTN analysis alone cannot tell us at all is timegaps. The OTN/TID combinations of, say, PCNYb 00100 and 00101 could have been generated 10 seconds, 10 minutes, or 10 hours apart – and there is simply no way to tell off surface-level information. Redeeming a GCEA Pokémon was quick: a speedy customer could generate one every 10-15 seconds, so timegaps could be tiny, or huge, if nobody was using a particular machine (or if it was left on overnight)!

This is where we must dig deeper. Technical sequencing picks up where common logic leaves off. Happily, the output of GCEA stations followed predictable pseudo-random patterns. Unseen by the end user, while active a GCEA station its pseudo-random number generator (PRNG) advanced with every frame for a total of 60 RNG calls per second. PCNY Pokémon their natures and IV spreads are derived from this PNRG state, and critically, so are their 8-digit hexadecimal Pokémon Identifiers (or PID).5Fun fact, species determination is done separately, and uses a modified version of Pokémon Stadium RNG, which is itself legacy from Gen2 PCNY. Why is this information useful to us? Well, because in a stroke of great fortune, we came to know the precise algorithmic variant. Normally unknowable to players, the discovery of DanTrain’s monolithic PCNY stash allowed Project Pokémon wizards to find and reverse-engineer the PID relationship between his Pokémon and thus crack the algorithm.

Algorithm in hand, we are able to group preserved PCNY into accurate, distinct sequences. We can assert with confidence, for example, that “CD Dragons” had a minimum of five unique C sequences, which is a lot, hinting at redistribution(s). And since we know that the GCEA station RNG advanced 60x/second, timegaps between Pokémon in a single chain emerge naturally.6False positives are rare. A full algorithmic cycle takes a theoretical 828.5 days to complete – that’s some ~4.3 billion unique PRNG states! Staying with Dragon Week, more than five hours separate PCNYc 149 Flygon from PCNYc 791 Seadra (~1.1 million frames). Such time intervals reveal how pressured a user was (or wasn’t) in their redeems, which provides clues to the popularity of a campaign at any given time. Inkydog’s hugely impressive 80d-190d Spring Fling sequence is a great example: a mere 78 minutes elapsed from start to finish, suggesting a constant tempo indicative of having had the place mostly to himself. Remarkable chains such as these allow us to speculate on the timing of particular sequences within a campaign (long chains on weekends); sequences that, in some instances, we’re able to retrace to specific dates. The aforementioned Dragon Week and Monster Mosh may both have comprised Day 1 of their respective distributions. And in what is perhaps sequencing’s greatest success, we were able to string together 2004 Box Pokémon from many different owners and prove conclusively distribution overshoot, thus confirming what scraps of anecdotal evidence had long indicated. In this manner, technical sequencing is the gateway to a veritable treasure trove of insights. Its potential only increases with more data points. (So please, if you own original PCNY, donate them for research!)

Finally, there’s another helpful dimension to sequencing: Pokémon authenticity. I’ve commented elsewhere how publication of the PCNY algorithm, the possible release of modified distribution software, or even the simple monetisation of existing equipment makes possible the full reproduction of PCNY Pokémon exactly as distributed all these years ago. However, armed with an exhaustive dictionary of historical PCNY sequences, we are able to identify even replicas that otherwise pass all checks. This is critical to the ultimate goal of maintaining an accurate historical record.

Now for the data itself. Each bloc below marked “Seq X” makes for a distinct chain. Where significant or notable timegaps exist between two surviving PCNY of a single sequence, these are given. As you will see, we don’t have very many examples of a sequence spanning multiple days, which could mean any number of things. It could mean the distribution hardware was manually reset more frequently than our information suggests – perhaps as a matter of routine maintenance, or to resolve software errors. It could also mean that the chief donators of our small sample size – GoldUrsaring, DanTrain, and Inkydog – liked to visit the Center on specific days only due to real-life commitments. Saturday shortly after a reset or a Sunday seem like good candidates. We also have a number of sequences of one, ie. Pokémon that don’t chain with anything else, which would be inherently suspect hadn’t they come from reliable sources before the PCNY algorithm was cracked.

Seq. D3: Saturday, August 28, 2004 (?)7Note: A “FRLG-related event” was held at PC New York on August 28, 2004. It is likely that the “Trade & Nature Power” campaign, scheduled to conclude the 27th, was reactivated to effectively overshoot its distribution window by a day and have the GCEA stations dispense its Pokémon to party guests. While we can’t be fully certain, the rapid rate of redeems in Inky’s primary sequence, coupled with the conspicuous absence of Fossils in his collection, is suggestive of acquisitions made on a busy Center (Satur)day different from EXEC’s.

All credit to Sabresite for developing sequencing tools and groundbreaking, trailblazing analysis.

  • 1
    When an irate visitor demanded that the GCEA stations be powered up for their kid to redeem Pokémon!
  • 2
    Source for these insights is former PCNY staffer Aurora.
  • 3
    Source for this latter tidbit is an anonymous employee close to the situation.
  • 4
    Most campaigns have a relative overabundance of Pokémon branded PCNYc compared to B and D. Why this is so is not entirely clear – it may relate to GCEA station positioning.
  • 5
    Fun fact, species determination is done separately, and uses a modified version of Pokémon Stadium RNG, which is itself legacy from Gen2 PCNY.
  • 6
    False positives are rare. A full algorithmic cycle takes a theoretical 828.5 days to complete – that’s some ~4.3 billion unique PRNG states!
