Prerelease:Pokémon Gold and Silver
This page details one or more prerelease versions of Pokémon Gold and Silver.
Pokémon Gold and Silver had a long development phase marked by delays and a shift from Game Boy to Game Boy Color. It went through a significant overhaul between its first reveal in 1997 and its release date, leaving traces of a very different game.

Initially, the games were announced as Pokémon 2, then lengthened to Pokémon Gold and Silver. Four Pokémon were initially shown in CoroCoro Comic – Ho-Oh, Slowking, Ampharos, and Donphan. The games were intended to be for Game Boy, with Super Game Boy support.
Add information from the Official Pokémon Fanbook (JP).
In May, a guide called ポケットモンスター公式ファンブック (Pocket Monsters Official Fanbook) was published by Shogakukan. It contained new details about the upcoming Pokémon titles, including an interview with director Satoshi Tajiri and producer Tsunekazu Ishihara.
In the interview, Satoshi Tajiri gave a few details about the games' story:
The protagonist begins collecting Pokémon when he hears rumours about a certain boy in Kanto Province who completed his entire Pokédex. That's where the story starts.
There is something unusual about this quote; the official Japanese name for Kanto is カントー地方 (Kantō-chihō), which translates to "Kanto region", with the word "Kanto" written in katakana. However, it is referred to here as 関東州 (Kantō-shū), meaning "Kanto Province", with the word "Kanto" written in kanji.
One page of the fanbook confirms that it is possible to trade between Gold and Silver and Generation I games.
In response to the question "Will characters such as the protagonist and trainers from the previous titles make an appearance?", Tajiri had this to say:
There's a different protagonist, but the story takes place in the same setting, so there's a strong possibility that you'll meet characters from the previous titles. You'll definitely be seeing Ash and Professor Oak again! Giovanni also left to go train in the last games, so... [laughter] Look forward to that.
Ash, known as Red, and Professor Oak did, indeed, go on to appear in Pokémon Gold and Silver. Giovanni was absent from the games, but much of the plot centers around his disappearance.
Tajiri stated that, while the number of Pokémon that would appear in the games was not yet officially decided, he wanted there to be over 100 more than before. He also mentioned that players would be able to evolve some of the Pokémon that didn't have evolutions in the previous games.
The cover of the fanbook featured official art for Donphan, Ampharos, and Slowking. These three Pokémon, along with Ho-Oh, were described in greater detail inside its pages.
|Early Sprite||Gold Sprite||Silver Sprite|
This powerful-looking new Pokémon seems like it could really pack a punch. The details are still unknown, but it looks like a Rhydon-type Pokémon, doesn't it?
This initial screenshot of Donphan is very close to its final Gold sprite, lacking only the multicolored palette, which the move to the Game Boy Color would provide. The shading is less detailed, as well.
|Early Sprite||Gold Sprite||Silver Sprite|
This new type of Pokémon looks as though it came from outer space. The name suggests that it might be an Electric Dragon Pokémon...? Its true nature is not yet known.
The Japanese name for Ampharos is デンリュウ (Denryū), which is a homonym for both 電流 (denryū), meaning "electric current", and 電竜 (denryū), which translates to "electric dragon". Ampharos's sprite received heavy reworking before the final games in order to more closely match Ken Sugimori's artwork for it. Originally, it had smaller horns and a shorter, rounder body. Its more Red and Green -like sprite had outlines broken by lighter pixels, a significant amount of white, and a monochromatic palette, which would be overhauled to match the hardware and art style of the final game.
Ho-Oh was the first of the creatures appearing in Pokémon 2 to be revealed. It's said that this legendary Pokémon will only reveal itself to a genius...
In Pokémon Crystal and Pokémon Y, Ho-Oh's Pokédex description states that "It will reveal itself before a pure-hearted trainer by shining its bright rainbow-colored wings." There is no mention of whether the pure-hearted player must also be intelligent.
Secret Data on Slowking
Slowpoke, a very stupid Pokémon, was out fishing for bait when a Shellder clamped onto on its tail, causing it to evolve into Slowbro. However, it is said that, in 1 instance out of 10,000, a Shellder will clamp down on a Slowpoke's head instead of its tail. As the Shellder's bites down, its essence penetrates the Slowpoke's listless brain cells, bestowing upon it extreme motivation.
Slowking has quickly become a hot topic among Pokémon collectors. How its evolution takes place is still unspecified, but it has been established that it evolves from Slowpoke!
In the final games' Pokédex entries and the anime, Slowpoke's evolution is described similarly to the above, but in gameplay, Slowpoke evolves into Slowking when it is traded while holding a King's Rock item.
This image was captioned "The starting town, Silent Hills". (This name predates the PlayStation video game Silent Hill, which wasn't released in Japan until January 1999.) In the final game, the protagonist's hometown is known as ワカバタウン (Wakaba Town), which translates to "Young Leaf".
- The houses are closer to the ones seen in Red and Blue. Their chimneys are unique to this iteration.
- While the trees are similar to those the final game in terms of size and shape, their detailing is slightly different.
- The female NPC in this image does not resemble any NPC from the final game.
The town in this image was captioned オールドシティ (Old City). It bears resemblance to both Violet City and Ecruteak City.
- The buildings are constructed with pagoda-like roofs, pathways of stones dot the ground in front of buildings, and the signposts in the city resemble traditional Japanese signposts. It seems that these are unique to this location, as other locations in these early builds have the typical square signs.
- A large tower looms over the rest of the city. This may have been an early version of Sprout Tower in Violet City, or one of the two towers in Ecruteak City.
The October 1997 edition of Monthly CoroCoro Comic magazine (published in mid-September) carried an advertisement for Space World 97's Mew giveaway event, in which 100,000 players would be given the opportunity to insert their game cartridge into a machine that would upload Mew into an empty slot in their party, provided they'd received the Pokédex. The advertisement stated that this Mew could be traded to Pokémon 2, confirming its compatibility with previous titles.
In October, the November 1997 issue of Monthly CoroCoro Comics showed off three new types of trainers, along with their official art, leaving the editors to speculate on what role they played and what kind of Pokémon they would use. These three were Firebreather, Schoolboy, and Lass. 
In mid-November, the December 1997 issue of CoroCoro was published, continuing on the theme of introducing three characters per issue. These characters were Kurt, Fisherman, and Kimono Girl. Kurt was specifically described as a non-trainer character, but his role in the game was still unknown. 
The first publicly playable demo of Pokémon Gold andSilver was then featured at Space World '97, a showcase event held in Tokyo from November 21 to 23. Gold and Silver kiosks were separated into two large rows, and players were able to choose which version they wanted to try. Playtime was limited to around 10 minutes.
A promo video was on display in the area, which incorporated both footage and still images.
The official guidebook for the event also featured two full pages dedicated to the game, as well as a shorter bio. The following screenshots were featured in the guidebook.
The held item mechanic, new to Generation II, was introduced in the guidebook with a quote from Professor Oak himself:
Big news! It seems that some of the Pokémon set to debut in Pokémon Gold and Silver have been found to carry items themselves. What's more, I hear that there are occasions when, if the Pokémon is intelligent enough, it will use the item it's holding to give it an advantage in battle. It also appears that when you trade Pokémon with a friend, you'll also be able to exchange items. I'm sorry, but that's all the information I have right now...
The professor also advertised a number of new Pokédex features:
I also had a hand in revising and improving the latest version of the Pokédex. Pages can now be flipped through 10 at a time, and it will even automatically search by Pokémon type - Water, Fire, Grass, etc.
The official guidebook introduced the protagonist thus:
A boy living in a certain town. He has a brother who's 3 years older. These days, his primary hobby is toying around with a hand-me-down computer that was given to him by his brother.
The rival's description follows:
The boy's rival. He lives in the same town. His appearance and personality differ from the rival in the previous games.
The guidebook also listed some of the trainers who would be opposing the protagonist, and included official artwork for each. These were Schoolboy, Lass, Firebreather, Kimono Girl, and Fisherman.
Names and official art for Ho-Oh, Slowking, Ampharos, and Donphan were published in the guidebook. While no specifically new details were provided, the designs and Japanese names for these new Pokémon were evidently finalized by this point.
The following Pokémon were allegedly encountered or mentioned in the playable demo. Because the only source for much of the information below is a Japanese fan site dedicated to cut Pokémon, a majority of this data's veracity is unclear. Despite this, screenshots of the game have been found confirming that at least three of the described Pokémon have a basis in the actual Pokémon seen at Spaceworld. The sketches are fan-made and sourced from the same site, which claims that they are based on official art.
|ハッパ||Happa||Grass||Chikorita||This Pokémon's name translates to "Leaf". It was one of three starters. Some of its available moves were Absorb, Tackle, Growth, and Leech Seed. Prior to the finding of its sprite, Happa was thought to be a more amorphous-looking Chikorita due to the fanart from Hakuda2 being somewhat inaccurate. In reality, Happa's appearance is exactly the same as the final Chikorita. The primary difference is that Happa's sprite is fully on-screen as opposed to being cut off at the legs like in the final. |
|ホノオグマ||Honōguma||Fire||[Unknown]||This Pokémon's name translates to "Fire Bear". It was one of three starters. Some of its moves were "Fire", Scratch, and Leer. It knew "Fire" from the beginning.|
|クルス||Kurusu||Water||[Unknown]||This Pokémon was one of three starters. Some of the moves it could learn were Tackle, Growl, and Water Gun.|
|プクー||Pukū||Water||Qwilfish||This Pokémon appears to be an early version of Qwilfish, whose final Japanese is Harīsen. "Buku buku" is a Japanese onomatopoeia for bubbling. Its design is less angry-looking compared to Qwilfish.|
|キリンリキ||Kirinriki||Dark/Normal||Girafarig||This Pokémon is an early version of Girafarig, with whom it shares a name. Its Pokédex entry described it as "Combo Pokémon". Two of its moves were Growl and Double Kick. It could be encountered in the tall grass just beyond the protagonist's hometown. Unlike the final Girafarig, it possesses two heads, rather than a sentient tail, and has shorter legs. |
|マリル||Mariru||[Unknown]||Marill||This Pokémon is an early version of Marill, with whom it shares a name. Aside from its pink color, it has smaller ears, and a differently-shaped body and tail.|
|[None]||サニー||Sunny||Grass||Sunflora||This Pokémon appears to be an early version of Sunflora, whose final Japanese name is キマワリ (Kimawari). Its Pokédex entry described it as a "Flower Pokémon". Some of its moves were Leech Seed and Sing.|
|[None]||ハネコ||Haneko||Grass/Flying||Hoppip||This Pokémon is likely an early version of Hoppip, whose final Japanese name is ハネッコ (Hanekko).|
|[None]||ワタコ||Watako||[Unknown]||[Unknown]||This Pokémon is likely an early version of Jumpluff, whose final Japanese name is ワタッコ (Watakko).|
|[None]||ペインター||Painter||Normal||Smeargle||This Pokémon may be an early version of Smeargle, whose final Japanese name is ドーブル (Dōburu). Its Pokédex entry described it as a "Fairy Pokémon", and it had the appearance of an artist.|
|[None]||ヨロイドリ||Yoroidori||Flying/Metal||Skarmory||This Pokémon's name translates to "Armor Bird". Its Pokédex entry described it as a "Bird Pokémon". It was likely an early version of Skarmory. While Skarmory's final Japanese name is エアームド (Eāmudo), it is described in the Pokédex as an "Armored Bird Pokémon". Yoroidori's name and type were mentioned in an article found on the PC on the protagonist's house, which announced the discovery of a new Pokémon type known as "Metal". In the final game, this type is called はがね (Hagane), meaning "Steel".|
|[None]||アクア||Aqua||[Unknown]||[Unknown]||The playable demo referred to this Pokémon only by name. Its name suggests that it's Water-type.|
|[None]||エレキング||Eleking||[Unknown]||[Unknown]||This Pokémon may be an early version of Elekid or a cut evolution for Electabuzz. Electabuzz didn't receive an evolution until Gen IV's Electivire, whose final Japanese name is エレキブル (Elekiburu), which is likely a pun on the Japanese pronunciation of the English loan words "electric" and "cable".|
|[None]||ネタモン||Netamon||[Unknown]||[Unknown]||This Pokémon's name is very similar to Ditto's Japanese name, Metamon. It could be encountered on a route.|
|[None]||ブクー||Bukū||[Unknown]||[Unknown]||This Pokémon could be encountered at night on a route near the player's house. It was described as resembling a flying squirrel. It's possible that Bukū was an early version of Sentret, whose final Japanese name is オタチ (Otachi).|
Pokédex entries for the following Pokémon allegedly appeared in a promo video on display at Spaceworld that explained the new features of the Pokédex. Because the only source for the information below is a Japanese fan site dedicated to cut Pokémon, its veracity is unclear.
|[None]||アクエリア||Aquaria||[Unknown]||[Unknown]||This Pokémon's name suggests that it's Water-type, and that it may be the evolved form of Aqua.|
|[None]||アニモン||Animon||[Unknown]||[Unknown]||"Animon" may be a portmanteau of the English word, "animate", and the Japanese word 文 (mon), meaning "letter" or "character". As such, it's possible that this Pokémon was an early version of Unown.|
|[None]||イカリ||Ikari||[Unknown]||[Unknown]||This Pokémon's name translates to "Rage". In the final game, "Ikari" (Rage) is a Pokémon move. The name may be a pun on イカ (ika), meaning "squid" or 錨 (ikari), meaning "anchor".|
|Spaceworld '97||Final (J)||Palette Glitch (J)|
This early version of the Gold title screen features animated leaves on a white background. A stationary Ho-Oh is emblazoned across the center. The title reads ポケットモンスター2 金 (Pocket Monsters 2 - Gold), with a stylized "2" partially visible behind the kanji.
Footage and descriptions of the Silver title screen has yet to be found, so it's unclear what it may have looked like. Lugia did not exist at this point in development.
At one point during the game's development, the Ho-Oh that appears on the title screen of Gold was rendered in color instead of silhouette. This functionality is still accessible in the final game by using a a glitch that causes Ho-Oh to be displayed in color, albeit with an incorrect palette. Conversely, the Lugia that appears on the title screen of Silver lacks these extra palette colors, suggesting that this title screen may have been created well after the developers decided to use silhouettes, and that Lugia was added significantly later in the game's development.
- The first town in the demo was not named in personal accounts, but its description resembles the picture of Silent Hills. It consisted of the player's house, Oak's lab, and a Pokémon Center. Players could meet the rival, watch a news story about Professor Oak, and leave the town by going west. The first route had Pidgey, Rattata, Pikachu, Marill, Sunflora, Ledyba, Hoppip, and Girafarig in the grass.
- The next area was a forest dungeon, similar to Ilex Forest. Caterpie and Metapod could be found in the grass. Various trainers could be fought in this area; each trainer had either Paras, Snorlax, Clefairy, Meowth, or Slowking. Trainers were named, and their trainer classes included Bug Catcher, Lass, Schoolboy, and Beauty.
- There is a gate at the end of the forest (perhaps the building with "GATE" above its doors, seen in screenshots) and the rival stands in front of it. If the player talks to the rival, the demo ends.
- According to visitor accounts, night and day had been implemented, along with Pokémon encountered only at night, and the real time clock also was functioning (although it may have been adjusted to show off the nighttime feature.)
Four screenshots of the overworld were included on page 35 of the Space World '97 Official Guidebook. The player sprite is not offset in any of them. These locations were not described in any accounts, and were possibly from the current non-demo stages of development at the time. The four screenshots have slightly different sprites for buildings, signs, fences, and floor tiles, likely as part of an attempt to make each location more unique.
- This area has a detailed radio tower as well as a male NPC, water, trees, a brick road, and a gate to another location. It most closely resembles Goldenrod City.
- The small trees' sprites are rounder and stumpier than their final versions.
A slightly later version of Old City. There are now two signposts, shockingly, and a male NPC stands in front of one of the doors to the tower.
- The tall trees have been updated and now more closely resemble their final iterations.
- The signpost here is square with a small base, and seems to be built into the fence.
A small town with a grassy area, with trees surrounding what looks like some ruins with a waterfall exiting a hole in the middle.
- The ruins have symbols on the walls that resemble Unown hieroglyphs in the Ruins of Alph.
- The doors on the buildings have three windows on them.
- The signposts look like the ones in the radio tower screenshot, but lack the fencepost borders.
The player Surfs across a stretch of ocean, avoiding newly found whirlpools. To the lower right is a section of land with tall grass that is protected by a line of Headbuttable trees. Above, a line of rocks keeps the player on their path.
- The small trees look notably like their final versions, as opposed to the small trees in the other screenshots. Whether this is another aesthetic difference or if these are different builds is unknown.
The overworld is also briefly visible in an incredibly washed-out snippet of preserved footage from the promo trailer. Once again, the player sprite is not offset.
This does not seem to resemble any final location in the game, but may have been early on in the game, or playable in the demo.
- These trees are the same as the ones seen in Silent Hills.
- A Cuttable tree is present.
A bridge over some water, separated by a fence. This most closely resembles the route to the north of Goldenrod City, but no discernable features or NPCs are present.
Battles were briefly showcased in surviving footage. Most of the battle interface is the same as the final.
- The Super Game Boy border is unique to this demo, with grinning Gengars at the top, and Pikachus lining the bottom. "Pokémon Gold" is repeated above and below the screen.
- Gust's type had been changed from Normal-type to Flying-type at this point.
- During the promotion video, the weather function was shown, with Poliwhirl using Rain Dance.
In December 1997, CoroCoro revealed the official art for the protagonist and the rival, identical to their final versions, as well as information that was already revealed at Spaceworld 97: descriptions for both characters, an upgraded Pokédex, Professor Oak's presence, held items, the release date and price, and the four previously seen in-game screenshots. 
Unknown date, 1997
A set of screenshots of unknown origin, most likely from 1997, as they feature similar graphics to the known early builds of the game.
- The first two screenshots appear to depict roughly the same location: a small town with fences, houses, trees, and NPCs.
- The latter two screenshots were found in several publications, such as the TV Gamer magazine,  and the third edition of a book called ポケットモンスターを遊びつくす本 赤 (Pocket Monsters Play Book - Red), published on Feb. 20th, 1998.  Notably, the player sprite is slightly offset from the center of the screen, unlike how the games normally function.
Gold and Silver were playable again at the January 1998 World Hobby Fair. Only one image survives from this event, showing Honooguma and Metapod. Assuming that the demo contained the same content, this battle would have been against a wild Metapod in the forested area.
- Unlike the Spaceworld 1997 demo, the game's palette may not have been completely configured for the Super Game Boy, as the entire screen is shaded with an orange palette.
- Metapod's sprite is unique to this demo.
- The SGB border for the game has changed from the earlier version seen at the Spaceworld demo.
Add info from here and other sources. Was this a playable demo?
Pokémon Gold and Silver was showcased at Space World '99, held at the end of August, where it was said to be 90% complete.
These screenshots can use comparisons with final.
These are screenshots of unknown origin, but the border may help identify the source. They're dated 1999-11-08. The multicolored screens indicate that the game has been fully ported to the Game Boy Color. The player sprite is not offset. Genders are not present on battle screens. The Bag layout is radically different.
The route has been changed slightly in layout, and the two female NPCs were replaced, mostly with eager Youngsters and Bug Catchers. The ledge which prevents progress earlier on by placing a Pokémon battle next to it is missing completely. The tile for normal Pokémon-free grass seems to have larger dark spots.
- The water tile resembles that of Red and Green.
- The brick bridge and the water are placed awkwardly and look strange, which was fixed in the final by making the edge of the water completely straight.

Prototype footprints can be seen on Pokédex screens - a generic footprint with the Pokédex number written within it. These are still located in the final, visible in the dex entries for glitch Pokémon #252 and #254-256. The footprint mark itself would become the final footprint for Donphan.
Farfetch'd's Pokédex description was the same as it was in Red and Green.
Clefairy uses its Pokédex entry from Pokémon Blue.
This screenshot appears to be from an older version of the game, possibly around Spaceworld 1997, as it has the 'new Pokémon under investigation' entry and Slowking's palette is monochromatic. Slowking's sprite has since been flipped horizontally. There is no red border between the description and the data, nor are there any sub-menu options such as listening to the cry. The Pokédex number text is missing as well. The border around the screen is an orange bevel, as opposed to the 1998 build above and the final version, which use a simpler red line with white highlights.

A build was showcased in footage shown on Nintendo's website. This showcases a much later version of the game, with more new Pokémon. Some sprites are different, but many elements resemble the final more than the Spaceworld demo. Notably, some Pokémon are encountered in the wild that are impossible to encounter in the final game, namely Slowking, Ampharos, and Togepi.
