Pokémon Gold and Silver Spaceworld '97 demo

The Pokémon Gold and Silver Spaceworld '97 demo is an early build of the games that was shown at Nintendo Space World '97 from November 21 to 23, 1997. At the time, the final game was estimated to be about 80% complete and was set to be released for the original Game Boy—the Game Boy Color would not be announced until late March of the following year.Pokemon Gold and Pokemon Silver Nintendo Space World 97 version - geocities.jp (archived; retrieved June 21, 2021)SPACEWORLD'97 Exhibit GAME BOY software vol.3 - nintendo.co.jp (archived; retrieved June 21, 2021) However, due to a variety of delays, including a complete overhaul to the game, it would not be released until late 1999.
During the two years after it was first shown at Nintendo Space World '97 until its final release in November 21, 1999, the game changed extensively from this early demo. As with the final games, the demo used the Japanese as its basis for development.
Up until 2018, little information was known about this demo, due to the majority of the game being locked off from players. Only a few photographs were taken, and most of the information known comes from testimony of attendees. On May 26, 2018, however, ROM files of both the Gold and Silver demos were anonymously posted online, including versions with debug menus, allowing players to explore data that was blocked off at Space World.
Beyond what was intended to be played appears unfinished: many Pokémon have unfinished and placeholder base stats, especially in Special Defense; scripts for events and NPC dialogue are completely absent, collision data is unfinished, and some areas, usually dungeons, are completely missing. Nevertheless, a large amount of information can be gathered from what is present, including many redesigned or scrapped Pokémon designs, minigame Easter eggs, and a completely different region. Additionally, the NPCs that remain give some implications for the original story; for example, an Imposter Professor Oak-like NPC can be seen in "High-Tech".
==Gameplay==
The demo begins with a monologue from Professor Oak, similar to the final game. However, there is no option to give the player a gender or a name, who is instead automatically a boy named Satoshi (サトシ) or Shigeru (シゲル). Afterwards, the player begins in his room in a town called Silent Hill (サイレントヒル); this town is also named Silent Hills (サイレントヒルズ) in the Official Fan Book of Pocket Monsters (Japanese: ポケットモンスター公式ファンブック), published earlier in 1997. The player will already have 3000 and eight Badges, although the Gym Leaders are blacked out. One of three first partner Pokémon, randomly chosen, is already placed in the player's party.
		
The player's Bag initially has the following items:
* 5 Poké Balls
* 10 Potions
* 10 Full Heals
* 1 (Japanese: きあいだま Fighting Spirit Orb), an early iteration of the Focus Band, which occupies the same slot as in the final game.
* 1 (Japanese: しげきだま Stimulus Orb). It is an item that prevents the holding Pokémon from , but it is not consumed upon use. It was dummied out in the final game as Teru-sama.
Silent Hill has exits to the west, north, and east; however, the northern and eastern exits are blocked to prevent the player from accessing unfinished areas. A Pokémon Center which the player can enter is present in the town, but all of its functions are unavailable. Silent Hill also has a laboratory, but it cannot be entered.
The player will then move west to Route 1, a typical route with a dungeon called Silent Hill (しずかなおか) in the middle. (Although the English translations for both サイレントヒルズ and しずかなおか are the same, they are written differently in Japanese: the town is a transliteration of the English term "Silent Hill" in katakana, and the dungeon area in Route 1 is the Japanese native translation for "Silent Hill," written in hiragana.) Silent Hill has the first Trainers to encounter in the game. They can only be challenged by directly talking to them, and won't have any dialogue when they lose. While prize money is given out, and one has a that knows , there is no way to spend money in the demo. After going through Silent Hill, the player reemerges on the other side of Route 1, where they will encounter another trainer. At the end of Route 1, the , automatically named Shigeru (シゲル), stops the player, and the demo ends. The demo will also end if the player blacks out.
==Differences from the final game==
The demo and the final versions of the Generation II games had numerous differences.
File:GS demo morning.PNG|Morning
File:GS demo day.PNG|Day
File:GS demo night.PNG|Night
The demo was meant to be played on Game Boy hardware and was not designed to take advantage of the colors available on a Game Boy Color; as such, the colors available through the Super Game Boy were less detailed. The day and night system is present, but due to running on a Game Boy color scheme, the change in colors for the time of the day are just shades of blue. Playing the final games on a Super Game Boy yields a similar effect.
The intro lacks music, and instead of showing the Generation II first partner Pokémon at the end of the intro, and are shown instead; , which was present in the final game's intro, has a slightly less detailed design.
Generation I Pokédex entries were carried over as placeholders for Pokémon until new Pokédex entries were able to be written for them. All Pokédex entries for Generation II Pokémon use the same placeholder text: In an odd occurrence, it was also possible to battle wild Pokémon twice in a row without moving from a grass panel; why this was an implemented feature at the time is unknown.
Kanto Route 1 music plays for all Routes. The music of Viridian City, Saffron City, and Pewter City plays for all cities and towns present. Trainer and wild Pokémon battles both use Pokémon Red and Green Gym Leader music. More tracks from Pokémon Red and Green are present for events that are not normally possible in this build.
===Type chart===
Several type match ups differed from the final version of the game. Notably, and would be super effective against Dark types, while Normal types would only take resisted damage from Dark-type moves, and would have been super effective against , and would be resisted by the Metal type instead of Poison type moves doing no damage. Additionally, and Poison remained super effective against each other, something that existed in Generation I, but was changed to Poison dealing neutral damage to Bug and Bug being resisted by Poison in the final version. and Dark would both deal neutral damage against Metal (like Generation VI onwards) instead of Metal resisting both types.
In the below type chart, bold text and a different shade of the color means that the type matchup is different than in the final version.

==Demo restrictions==
As this game was meant to be publicly played at Space World '97, there were several restrictions put in place to make sure the game could not lock up or be set up to not work for other players. The only options available at the start screen are "ポケモンを あそぶ" (Play Pokémon) and "せっていを かえる" (Change Settings). There is no Continue option as the player is not able to save in the demo build. The player is given a random level 8 first partner Pokémon.
The player could only heal using Potions as Pokémon Centers are not accessible in the demo. PCs are also not able to be used. Trying to visit a Pokémon Center or use a PC gives the text of "under repair" or "being adjusted." While prize money is given out, and one has a that knows , there is no way to spend money in the demo. This was likely to prevent a single attendee from hogging the demo by repeatedly healing to avoid blacking out.
The and rival's names are random pre-selected names. First partner Pokémon and wild Pokémon that appear in the demo are not able to evolve. The player can only challenge NPCs by talking to them directly. When an NPC loses, they do not have any losing dialog, presumably to make the demo faster to play. The player can only visit Silent Hill and early routes up to the forest area. When all the player's Pokémon faint, the game returns to the title screen to ensure the next person could have a turn.
==Pokémon==
Although only a few new Pokémon can be seen in the demo through normal gameplay, 100 new Pokémon had been designed at the time. Some of these Pokémon were kept into the final release largely unchanged; some had major modifications; others went completely unused. 16 of the unused Pokémon were related to the original 151 Generation I Pokémon, and two of the unused Pokémon were related to Generation II Pokémon which made it into the final release.
Many of the 151 Generation I Pokémon still used their sprites from Pokémon Blue as placeholder sprites during this time. Several Pokémon would have also gained either an Evolution or a pre-Evolution. Certain scrapped Pokémon correspond to, and may have inspired, later-generation Pokémon such as or .
Many new Pokémon that were unused in the demo had placeholder base stats, which were all 50.

===Special entry animations===
 and Sanī used the special "stars" animation, which would be later used for Shiny Pokémon. However, this demo lacked a special animation linked to Shininess.Pokémon Gold and Silver/Spaceworld 1997 Demo/Pokémon → Shinies | The Cutting Room Floor
Hōhō used a special "fade-in" animation, which remains in the final games, but is unused.
There was also a special "wave" animation, which was unused even in the demo.
===Shiny Pokémon===
Shiny Pokémon had much different mechanics than in the final games. Instead of exact DV requirements (Defense, Speed and Special DVs at 10, and Attack DV of 2, 3, 6, 7, 10, 11, 14 or 15), all Shiny Pokémon had DVs of 10 or higher for all stats other than HP, which translates to Shininess odds of 81/4096, or ~1.977%. Shiny Pokémon had no special star animation when sent out, although that animation is implemented in-game. For some reason, it only applies to non-Shiny and Sanī.
Due to technical limitations caused by the Super Game Boy's hardware, each color palette also had an assigned Shiny palette. Thus, all Pokémon with a given color palette also had the same Shiny palette.

==Trainer Classes==
In the demo, the majority of trainer classes present would go on to be unused or have drastic character redesigns when compared to the final game. In this build, the Gym Leader "classes" work just like in Generation I, with each entry only being the character's name. In the final release they're all just known as Gym Leader, with their name added after it.

01 	ハヤトHayato 	ジムリーダーGym Leader 	 	 	 	 	The first Gym Leader, Falkner, has a different design. Leader of Old's Gym.
02 	アカネAkane 	ジムリーダーGym Leader 	 	 	 	 	The second Gym Leader, Whitney, uses a placeholder sprite and reuses a copy of Bugsy's overworld sprites, though Whitney also is listed as the second Gym Leader internally in the final. West's Gym has Bugsy as the leader, meaning he may have already been decided as the second leader at an earlier point. It is unknown where she would have been battled, though a female Gym Leader can be found in High-Tech's Gym.
03 	ツクシTsukushi 	ジムリーダーGym Leader 	 	 	 	 	The third Gym Leader, Bugsy, has a different design. Can be found in West's Gym.
04 	エノキEnoki 	ジムリーダーGym Leader 	 	 	 	 	The fourth Gym Leader, Morty, has a different design. Overworld sprites depict him with a ponytail, though this is never used in the demo. It is unknown where he would have been battled, though the Birdon Gym features pitfalls much like Morty's in the final game and is also the fourth city with a Gym, suggesting that he may have still been the fourth leader. Enoki was the name given to Morty in Ken Sugimori's early conceptual sketches for the characters.https://web.archive.org/web/20230201102400/https://twitter.com/SUPER_32X/status/566790273804419073 It seems to originate from the Japanese name of the , often referenced in folklore surrounding the ghostly light , a kind of Will-o'-the-wisp.
05 	オケラOkera 	ジムリーダーGym Leader 	 	N/A 	 	N/A 	The fifth Gym Leader, seemingly related to Pryce. Uses a placeholder sprite and reuses a copy of Jasmine's overworld sprites. The name Okera was Pryce's name early in development,https://twitter.com/xdanieldzd/status/1253849097062285313 with this class sharing the same ID of Pryce in the final game. It is unknown where he would have been battled, though Newtype would be the next Gym after Birdon and contains a male leader.
06 	ミカンMikan 	ジムリーダーGym Leader 	 	 	 	 	The sixth Gym Leader, Jasmine, has a different design. Her overworld sprites go unused in the demo, so it is unknown where she would have been battled, since the gym in Blue Forest appeared to be a Ghost gym. It may suggest that Jasmine was originally a Ghost-type leader, or that the map was based on an even earlier arrangement of leaders.
07 	ブルーBlue 	ジムリーダーGym Leader 	 	N/A 	 	N/A 	The seventh Gym Leader, seemingly . Uses a placeholder sprite, with an overworld sprite of Red being in the Kanto Gym. ブルー is the default name for the player in . This does not refer to the rival character , who is known as Green in Japan. It is unknown where he would have been battled, though the aforementioned Kanto Gym appears to be most likely, a role ironically fulfilled by the rival character Blue in the final game. This slot was given to Chuck in the final version.
08 	ガマGama 	ジムリーダーGym Leader 	 	N/A 	 	N/A 	The eighth Gym Leader, uses a placeholder sprite. Gama may come from the Japanese name of the of the genus Typha, which is named after —a serpentine giant in Greek mythology. It is unknown where they would have been battled, though due to their placement as the final Gym Leader, this may be an early iteration of Clair, who uses Pokémon that fit a similar description in the final game, such as Dragonair and Gyarados. There is a Gym in Stand, but it is just a placeholder.
09 	ライバルRival 	ライバルRival 	 	 	 	 	This Trainer class doesn't use the class name, just the name assigned to it.
0A 	オーキドはかせProfessor Oak 	ポケモンはかせPokémon Professor 	 	 	 	 	The name is different in the final version.
0B 	サカキSakaki 	してんのうThe Big Four 	 	 	 	N/A 	Giovanni, uses a placeholder sprite. In the demo, Giovanni is found in the Radio Tower in West, meaning he was planned to be encountered there. Giovanni is absent from the final version, and this slot was given to Will.
0C 	しゅじんこうProtagonist 	ポケモントレーナーPokémon Trainer 	 	 	 	 	This Trainer class doesn't use the class name, just the name assigned to it. The name is different in the final version.
0D 	シバSiba 	してんのうThe Big Four 	 	 	 	 	Bruno, uses a placeholder sprite that appears to look like Kurt, which had a sprite even in the Pokémon Gold and Silver Spaceworld '99 demo before the idea of Kurt as a Trainer was dropped.
0E 	カスミKasumi 	してんのうThe Big Four 	 	 	 	 	Misty, uses a placeholder sprite. Due to how this section of Trainers was shuffled around, Misty was probably not intended to be an Elite Four member. Misty's entry ended up being moved to 0x12, and this ID spot was given to Karen.
0F 	カンナKanna 	してんのうThe Big Four 	 	 	 	N/A 	Lorelei, uses a placeholder sprite. This character doesn't exist in the final version, and this slot was given to Koga.
10 	ワタルWataru 	チャンピオンChampion 	 	 	 	 	Lance, uses a placeholder sprite. It is unknown if Lance was intended to be the at that time.
11 	ゲルゲだんいん♂Geruge Member♂ 	ジムリーダーGym Leader 	 	 	 	N/A 	The unused Geruge Member Trainer class, which has a clone at index 0x3E. Both versions use a placeholder sprite. Geruge (Japanese: ゲルゲトショッキングセンター Gerugeto Shocking Center, ゲルゲ Geruge for short) was a popular Japanese radio show that hosted various Japanese celebrities. They would likely be found in the Radio Tower. This slot was given to Brock in the final version.
12 	さんにんしゅうTrio 	ジムリーダーGym Leader 	 	 	 	N/A 	The unused Trio Trainer class, which uses a placeholder sprite. They may have inspired the Wise Trio in . This slot was given to Misty in the final version.
13 	さんにんしゅうTrio 	ジムリーダーGym Leader 	 	 	 	N/A 	This slot was given to Lt. Surge in the final version.
14 	さんにんしゅうTrio 	はぐれけんきゅういんResearcher Gone Astray 	 	 	 	N/A 	This slot was given to the class in the final version.
15 	ロケットだんいん♀Rocket Member♀ 	ジムリーダーGym Leader 	 	 	 	 	The female class, which uses a placeholder sprite. This class was moved to 0x42 in the final version, and this slot was given to Erika.
16 	たんパンこぞうShorts Youngster 	たんパンこぞうShorts Youngster 	 	 	 	 	The class, who had a different design.
17 	じゅくがえりComing Home from Cram School 	じゅくがえりComing Home from Cram School 	 	 	 	 	The class.
18 	ひよっこFledgling 	とりつかいBird Tamer 	 	 	 	N/A 	An unused Trainer class that was meant for beginning Trainers. It had similarities to the class in later generations. Suggesting by the name that could be taken to mean "chick" or "fledgling", but also "novice" or "rookie", this may have had ties with the class by being a child version of it, much like es grow up to be . Coincidentally, this slot was given to the Bird Keeper class in the final version.
19 	ミニスカートMiniskirt 	ミニスカートMiniskirt 	 	 	 	 	The class. The sprite is similar to the final, but with the appearance of a Generation I Lass.
1A 	てんさいGenius 	ジムリーダーGym Leader 	 	 	 	N/A 	The unused Genius class, uses a placeholder sprite. This slot was given to Janine in the final version.
1B 	プロフェッショナル♂Professional♂ 	エリートトレーナーElite Trainer 	 	 	 	 	The unused Professional class, meant as a replacement to the class. Has a whip, like Generation I Cooltrainers.
1C 	プロフェッショナル♀Professional♀ 	エリートトレーナーElite Trainer 	 	 	 	 	The unused Professional class, meant as a replacement to the class. Has a whip, like Generation I Cooltrainers.
1D 	おとなのおねえさんGrown-Up Woman 	おとなのおねえさんGrown-Up Woman 	 	 	 	 	The class. The sprite is similar to the final, but with the appearance of a Generation I Beauty.

21 	せんせい♂Teacher♂ 	スキーヤーSkier 	 	 	 	N/A 	The male class. As seen on an unused team from the Spaceworld '99 demo, this Trainer class would focus on masculine Pokémon like . This slot was given to the class in the final version, and male Teachers have never been seen since.
22 	せんせい♀Teacher♀ 	せんせいTeacher 	 	 	 	 	The female Teacher class. She drops the gender symbol in the final release.
23 	とっちゃんぼうやManchild 	ジムリーダーGym Leader 	 	 	 	N/A 	Uses a placeholder sprite. The name suggests it was probably a prototype of the class. This slot was given to Sabrina in the final version.
24 	むしとりしょうねんBug Catcher Boy 	むしとりBug Catcher 	 	 	 	 	The class, has a different name in the final version.
25 	つりびとFisher 	つりびとFisher 	 	 	 	 	The class. Has a cigarette, referencing the common Japanese stereotype of smoking fishermen. It can be seen on the final sprite, but was removed in the localizations.

==Maps==
Although only and the route and forest leading from it to are accessible in the demo, an almost fully mapped, albeit unpolished region is visible. However, the inaccessible locations use an outdated form of collision that makes areas inaccessible without debug mode; most notably, grass tiles are often treated as walls. Warps data is functional and all accessible houses feature NPCs, though dungeon maps are completely unused and the Pokémon League equivalent is nonexistent. No Trainer battles exist beyond the demo area, but a scant few areas have wild Pokémon, featuring some prototype Pokémon, averaging around level 30.
The final map of Johto bears little resemblance to the region present in the demo, which was based on the entirety of Japan, with Kanto included as a large city within it. Apart from Kanto and a prototype of the Ruins of Alph, none of the areas from the final game appear in the demo; however, some maps bear similarities.
