The Pokémon Gold and Silver demo is an early build of the games Pokémon Gold and Silver shown at Nintendo Space World '97 from November 21 to 23, 1997. At the time, the final game was estimated to be about 80 percent complete and was set to be released for the original Game Boy, as the Game Boy Color had not yet been announced, in late March of the following year. [1][2] 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 Pokémon Blue 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; scripts, NPCs, and warp data is largely absent; collision data is missing; and some areas 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.


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). Afterwards, the player begins in his room in a town called Silent Hills (サイレントヒルズ). The player will already have 3000PokémonDollar.png and eight badges, although the Gym Leaders are blacked out. One of three starter Pokémon, randomly chosen, is already placed in the player's party.

Silent Hills 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 Hills 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 Hills" 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. 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 rival, 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.

Morning Day Night The demo was meant to be played on Gameboy hardware and was not designed to take advantage of the colors available on a Gameboy Color; as such, the colors available through the Super Gameboy 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 Gameboy yields a similar effect.

The intro lacks music, and instead of showing the Generation II starters at the end of the intro, Venusaur and Blastoise are shown instead; Charizard, 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:「はっけんされた ばかりの ポケモン げんざい ちょうさちゅう。」 ("Now investigating this newly discovered Pokémon.") 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, Normal-type and Dark-type would be super effective against Dark-types while Normal-types would only take half-damage from Dark-types, Water-type and Electric-type would have been super effective against Steel-type, and Poison-type would be resisted by the Steel-type instead of Poison-type moves doing no damage.

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 starter Pokémon.

The player only has Potions as PokéCenters are not accessible in the demo. PCs are also not able to be used. Trying to visit a PokéCenter or use a PC gives the text of "under repair" or "being adjusted." This is likely to prevent a single attendee from hogging the demo by repeatedly healing to avoid blacking out.

The player and rival's names cannot be selected or made and are instead given random pre-selected names. Starter Pokémon and wild Pokémon are not able to evolve to prevent their discovery. When an NPC loses, their losing dialog is not present to allow for more playing time in the demo. The player can only visit Silent Hill and early routes up to the forest area. When all the player's Pokémon faint, the game boots back to the title screen for the next person to play.


Main article: Pokémon Gold and Silver demo/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. 62 of these Pokémon were used in the final games, and 29 of these Pokémon received various changes before their release in the final games. 38 Pokémon 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. 20 of the unreleased Pokémon were not related to any existing Pokémon.

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 Leafeon or Lickilicky.

Main article: Pokémon Gold and Silver demo/Locations

File:Johto Town Map GS Demo.png Although only Silent Hill and the route and forest leading from it to Old City are accessible in the demo, many other locations are programmed into the game. However, the inaccessible locations lack collision and warp data.

The final map of Johto shares 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.


This build of the game contained far more mini-games, with a total of 5.

Title screen

A hidden mini-game involving Pikachu can be played if the game is left idle at the title screen for an extended period of time. The player tries to avoid obstacles and collect musical notes while catching up to Jigglypuff. The game ends once Pikachu catches up to Jigglypuff and returns to the title screen. After playing, the title screen will have musical notes flying across the screen, rather than fire.


A picross mini-game featuring Pokémon was present.

Some Pokémon picross puzzles would later appear in Picross NP Vol. 1. Pokémon Picross would also be announced for the Game Boy Color; however, it was ultimately cancelled. A Pokémon picross game would not be released until Pokémon Picross in December 2015.


The poker mini-game was based on the real-life game of poker but with various Pokémon on the cards instead of clubs, diamonds, hearts, and spades. It would be replaced with card flip in the final version of the game.

Memory game

A memory game is a game where the player attempts to match five pairs of cards in five turns. However, no coins are actually rewarded for any matches. This game remains unused in the final game.

Slide puzzle

The last mini-game is a 15-tile slide puzzle game where the player has to try rearranging the tiles to reveal who the Pokémon is.

With the introduction of held items, many new items and Key Items were added that would be cut, have slight changes in how they worked, or be scrapped altogether.
