Proto:Pokémon Gold and Silver/Spaceworld 1999 Demo/Pokémon

This is a sub-page of Proto:Pokémon Gold and Silver/Spaceworld 1999 Demo.

This article is a work in progress. ...Well, all the articles here are, in a way. But this one moreso, and the article may contain incomplete information and editor's notes.

While the Pokédex is starting to resemble the final game's, there are plenty of unusual differences to note. Several Johto Pokémon also use placeholder sprites (or even leftovers from the Spaceworld '97 demo) and/or cries. Please note that for a more accurate comparison of how the sprites evolved throughout the game's initial development, the Final sprites shown on this page are from the game's original Japanese release. A handful of sprites underwent further changes during the localization process prior to the game's international release, full details of which can be seen here.

195	Wooper									マダーム Madaamu	Gold sprite has a different design which depicts Wooper with a quadrupedal body shape, differently shaped gills, and no markings on its chest. Silver sprite is a duplicate of the Gold one. Uses the name, backsprite, and menu sprite of Madame, the unused Farfetch'd evolution from Spaceworld '97, and also uses its typing, Normal/Flying, and its moveset, implying Madaamu was originally supposed to be here. Its cry is Remoraid's cry played at a lower pitch. Quagsire occupies this Dex spot in the final game, while Wooper was moved to spot 194.
196	Espeon									エーフィ Eefi	Gold sprite is almost similar to the final, albeit smaller and with a design similar to the one seen in the Spaceworld 1997 demo. Silver sprite is similar to the final, but was refined. Reuses its back sprite from June 1999, albeit with updated shading.
197	Umbreon									ブラッキー Burakkii'	Gold sprite matches the final. Silver sprite is similar to the final, but was refined and flipped horizontally. Reuses its back sprite from June 1999, albeit with updated shading. Its cry is totally different.
198	Murkrow									ヤミカラス Yamikarasu	Gold sprite is almost identical to the final, albeit with missing toes. Silver sprite is similar to the final, but was refined.
199	Slowking									ヤドキング Yadokingu	Gold sprite is identical to the final. Silver sprite is similar to the final, but was refined. Reuses its back sprite from June 1999.
200	Misdreavus									ノロワラ Norowara	Gold sprite is identical to the final. Silver sprite has a totally different pose and seems to be an earlier version of the Gold sprite. Uses the name of Norowara, a Ghost type Pokémon which was in the Spaceworld '97 build of the game.
201	Unown									アンノーン Unown	The sprites for Unown and all of its alphabetical variants are identical to the final.
202	Wobbuffet									ツインズ Tsuinzu	Uses the name of Tsuinzu, the unused Girafarig pre-evolution from Spaceworld '97, and the backsprite shows another unused pre-evolution of Girafarig. Its moveset is similar to Girafarig's and it even evolves into it at level 24. Its red palette seems to be a leftover of Tsuinzu's previous design, and it's a Psychic/Normal type. Unfortunately, whatever this iteration was meant to represent is still little more than an outline. Interestingly, the temporary front sprite used matches the outline of Wobbuffet's final back sprite flipped upside down. In the final, Wobbuffet shares the Dex spot, Psychic type and a similar concept, and has various design similarities to the various Twins incarnations, suggesting that Tsuinzu was reworked into Wobbuffet.
203	Girafarig									キリンリキ Kirinriki	Gold sprite is almost identical to the final. Silver sprite is similar to the final, but was refined.
204	Pineco									クヌギダマ Kunugidama	Both front sprites were refined for the final game, and so was the backsprite. It is a Grass-type instead of a Bug-type, and it does not evolve. Uses the quadruped menu icon instead of the clawed bug icon.
205	Shuckle									ツボツボ Tsubotsubo	Has a very differently shaped shell, bearing close resemblance to a vase, as well as featuring a longer neck and thinner tentacles. Shuckle's Dex number is 213 in the final game, while Forretress is the one occupying 205.
206	Dunsparce									ノコッチ Nokocchi	Both sprites showcase much simpler designs which appear to be closer to the traditional look of the Tsuchinoko, a mythical Japanese snake creature on which Dunsparce is based. Noticeably, the wings and drill shaped tail are absent from these early sprites, as are the blue stripes, which are instead filled by small black spots on either side of its body on the Gold front sprite. The eyes are also much simpler, and the Gold sprite features a blue tongue which is never seen anywhere else.
207	Gligar									グライガー Gligar	Both sprites match the final.
208	Steelix									ハガネール Haganeeru	Gold sprite is almost identical to the final. Silver sprite is similar to the final, but was refined.
209	Snubbull									ブルー Buruu	Both its front sprites have white collars instead of blue. Gold sprite almost matches the final, albeit with some minor alterations to the face. Silver sprite is similar to the final, but was refined.
210	Granbull									グランブル Granbull	Gold sprite is almost identical to the final. Silver sprite has a totally different pose.
211	Qwilfish									プクー Pukuu	Gold sprite is reused from the Spaceworld 1997 demo. Silver sprite is similar to the final, but was refined. Still uses its early name, "Pukuu", from the Spaceworld '97 demo.
212	Scizor									ハッサム Hassamu	Gold sprite is almost identical to the final. Silver sprite has a totally different pose.
213	Forretress									プラックス Purakkusu	Gold sprite is only a basic outline at this point. Silver sprite is a duplicate of the Gold one. Uses the name and backsprite of of the unused Pinsir evolution from Spaceworld '97. Forretress' Dex number is 205 in the final game, while Shuckle is the one occupying 213.
214	Heracross									へラクロス Heracross	Gold sprite is almost identical to the final. Silver sprite is similar to the final, but was refined.
215	Sneasel									ニューラ Nyuura	Both sprites have totally different sprites and use Sneasel's design from the Spaceworld 1997 demo, albeit with the Gold sprite missing its tail. Reuses its backsprite from the Spaceworld '97 demo. Its cry is Donphan's cry played at a higher pitch.
216	Teddiursa									ヒメグマ Himeguma	Gold sprite appears to be a redrawn version of Honooguma's from the Spaceworld '97 demo. This, in addition to the similar Japanese names, suggest that Teddiursa might have been based on Honooguma's design. Silver sprite has a totally different pose. Backsprite is similar to the final, but was refined.
217	Ursaring									リングマ Ringuma	Both sprites match the final.
218	Magcargo									マグマッグ Magumaggu	Both sprites have similar poses, but lack their shell flames, lava bubbles, have smaller, cross-eyed eyes, and a palette which more closely resembles Magcargo's color scheme from future games in the series. Uses Slugma's name as well as its height and weight. Uses the monster menu icon instead of the slime icon. Slugma occupies this Dex spot in the final game, while Magcargo was moved to spot 219. Its cry is unfinished.
219	Corsola									みてい8 mitei 8	Gold sprite matches the final. Silver sprite is a duplicate of the Gold one, while, in the final game, Silver has its own unique sprite. Uses the placeholder "Mitei" name. Uses the backsprite and typing of the Mr. Mime pre-evolution from Spaceworld '97, and its cry is unfinished. Corsola's Dex number is 222 in the final game, while Magcargo is the one occupying 219.
220	Swinub									みてい8 mitei 8	Both sprites match the final. Uses the placeholder "Mitei" name. Evolves at level 15, instead of level 33.
221	Piloswine									イノムー Inomuu	Both sprites match the final.
222	Slugma									みてい10 mitei 10	Gold sprite has differently, more stereotypical "slug eyes" than the final design, in addition to lacking the magma-themed bubbles and "drool" seen in the final sprite. The color palette also bears a closer resemblance to Magcargo's final sprite palette than Slugma's. Silver sprite is a duplicate of the Gold one. Its backsprite is very crude and unrefined, indicating it wasn't quite finished at this point in development. Uses Magcargo's height and weight and uses the "Mitei" placeholder name. It is an Ice/Ground-type. Uses the quadruped menu icon instead of the slime icon. Corsola occupies this Dex number in the final game, while Slugma was moved to 218.
223	Remoraid									テッポウオ Teppouo	Gold sprite reuses its sprite from the Spaceworld '97 demo. Silver sprite is in a similar pose to the final sprite, but still uses the Spaceworld '97 design.
224	Octillery									オクタン Okutan	While Octillery no longer wears a helmet, the design is otherwise similar to that seen in Spaceworld '97. Both sprites have similar poses to their final counterparts. Reuses its back sprite from the Spaceworld 1997 demo, albeit with updated shading.
225	Delibird									ギフト Gifuto	Gold sprite is the same as the one from June 1999. Silver sprite is similar to the final, though it also features the "June 1999" design. Back sprite is the same as the June 1999 one, albeit with updated shading. Still uses its early name, "Gifuto" ("Gift"), from the Spaceworld '97 demo.
226	Mantine									ハネエイ Haneei	Still uses its early name, "Haneei", from the Spaceworld '97 demo. Has a differently shaped "mouth" more in line with that of real-life manta rays. Additional differences between these front sprites and the final sprites can also be spotted in the patterns on its fins and chest, as well as its antennae being further spaced out. Also apparent are the fish on its underside, which appear to be torpedo-like featureless fish rather than the Remoraid seen in the final design, as well as having two as opposed to just one. Moreover, only the proto Goldsprite depict these "Remoraid" with a face. Its cry is shorter, and only repeats once, instead of twice.
227	Skarmory									ヨロイドリ Yoroidori	Both sprites match the final. Still uses its early name, "Yoroidori", from the Spaceworld '97 demo.
228	Houndour									デビル Debiru	Gold sprite matches the final. Silver sprite almost matches the final, but was refined. Still uses its early name, "Debiru", from the Spaceworld '97 demo. Backsprite is almost identical to the final, but features a spine-like series of bone protrusions, similar to the ones seen in the Spaceworld 1997 backsprite.
229	Houndoom									へルガー Herugaa	Gold sprite matches the final. Silver sprite almost matches the final, but was refined.
230	Kingdra									キングドラ kingudora	Gold sprite and backsprite are reused from the Spaceworld '97 demo. Silver sprite has a totally different pose, and still uses Kingdra's early design. Uses the snake menu icon instead of the dragon icon.
231	Phanpy									パオン Paon	Gold sprite and back sprite resemble the ones from June 1999, albeit touched-up and matching the final design. Silver sprite almost matches final, but was refined. Still uses its early name, "Paon", from the Spaceworld '97 demo.
232	Donphan									ドンファン Donphan	Gold sprite matches the final. Silver sprite almost matches the final, but was refined.

234	Stantler									オドシシ Odoshishi	Gold sprite matches the final. Silver sprite almost matches the final, but was refined.
235	Smeargle									ドーブル Dooburu	Gold sprite matches the final. Silver sprite almost matches the final, but was refined.
236	Tyrogue									ゴング Gongu	Gold sprite and back sprite are reused from the Spaceworld '97 demo. Silver sprite also uses the Spaceworld '97 design, and features a different pose which may have been inspired by Hitmonchan's Gold sprite. Still uses its early name, "Gongu" (Gong), from the Spaceworld '97 demo.
237	Hitmontop									カポエラー Kapoeraa	Gold sprite and back sprite are the same as the June 1999 ones. Silver sprite has a totally different pose, and also uses the updated early design.
238	Smoochum									キスキス Kisukisu	Gold sprite almost matches the final, albeit with some shading differences. Silver sprite almost matches the final, but was refined. Reuses its backsprite from the Spaceworld '97 demo. Uses a different name, with it being Kisukisu (Kisskiss), as opposed to ムチュール Muchuuru, its final name, or even Rippu (Lipp), its name from the Spaceworld '97 demo.
239	Elekid									キッド Elekid	Gold sprite matches the final. Silver sprite almost matches the final, but was refined.
240	Magby									エレブビィ Bubii	Gold sprite almost matches the final, but was refined. Silver sprite matches the final.

242	Blissey									ハピナス Hapinasu	Both sprites match the final.
243	Raikou									ライ Rai	Gold sprite is almost identical to the final, albeit with Raikou's fangs being red and much longer than they are in the final game. Silver sprite uses the early design and has a totally different pose, and, in the final game, both Gold and Silver share the same sprite. Backsprite is totally different. Still uses its early name, "Rai", from the Spaceworld '97 demo.
244	Entei									エン En	Gold sprite is almost identical to the final, albeit with Entei sporting a larger tuft of fur in the front. Silver sprite uses the early design and has a totally different pose, and in the final game both Gold and Silver share the same sprite. Still uses its early name, "En", from the Spaceworld '97 demo. Its cry is played at a different pitch.
245	Suicune									スイ Sui	Gold sprite matches the final. Silver sprite uses a totally different pose, and in the final game both Gold and Silver share the same sprite. Still uses its early name, "Sui", from the Spaceworld '97 demo. Gold sprite matches final.

251	Celebi									みてい12 mitei 12	Gold sprite and back sprite have a totally different pose and color scheme, and a design which appears to be based on Kokopelli, a fertility deity in some Native American cultures. Silver sprite is a duplicate of the Gold one. Uses the placeholder "Mitei" name. It also has a different species name, being listed as the "Plant Pokémon" instead of the "Time travel Pokémon", it is a Normal-type instead of a Psychic/Grass-type, and it is one kilogram heavier than in the final game.

Footprint Changes

As it turns out, some of the footprint graphics differ between the ones used in this prototype and the ones used in the final game.

This placeholder graphic can be seen used in the Pokédex entries for Chinchou, Azumarill, Sunkern, Wobbuffet, Corsola, an Celebi. In the final game, all these Pokémon were given their own unique footprint, with exception of Sunkern, as its finalized design lacks feet of any kind.

Tentacool uses a footprint which is shaped like the extremity of its tentacles, while it doesn't have any footprint in the final game (and the rest of the franchise for that matter).

Tentacruel uses a small round footprint which seems a bit too small to represent the extremity of its tentacles. Much like with Tentacool, Tentacruel doesn't have any footprint in the final game (and the rest of the franchise for that matter).

Exeggcute, for some odd reason, uses a medium-sized round footprint despite it not having feet of any kind. Unsurprisingly, it doesn't have any footprint in the final game (and the rest of the franchise for that matter).

Interestingly, the footprint used by Lanturn appears to have been intended for Tsubomitto, as it matches the general shape of its feet. This makes sense as Lanturn was built off Tsubomitto, reusing its name, typing, and back sprite, while Tsubomitto itself was apparently still planned to be included in the final game by June of 1999, making it clear it had received a footprint of its own by then. Meanwhile, in the final game, Lanturn doesn't have a footprint.

Also worth noting is the footprint used by Wooper, which appears to have been intended for Madame, as it matches the general shape of its feet. This makes sense as Wooper was built off Madame, reusing its name, typing, back sprite and menu sprite, while Madame itself was apparently still planned to be included in the final game by June of 1999, making it clear it had received a footprint of its own by then. Interestingly enough, Wooper still uses this exact same footprint in the final game, despite having totally different feet. This oddity/oversight would later be fixed in subsequent games.

Piloswine	Slugma

Interestingly enough, the Spaceworld '99 version of Slugma (known there as "Mitei10") uses a footprint which appears to be a larger version of the one used by Piloswine. This could reinforce the theory that Slugma was built off of a short-lived cut Piloswine evolution, as in this build it also uses the "Quadruped" menu sprite and the Ice/Ground typing, much like Swinub and Piloswine. Further proof could also be found in the Gold CBB Scratchpads, with Slugma's entries containing a larger Piloswine sprite, and Swinub's containing a smaller Piloswine sprite (which could mean the developers were trying to repurpose Piloswine as a middle stage evolution). Meanwhile, in the final game Slugma doesn't have a footprint, and Piloswine would only get an evolution in Generation IV in the form of Mamoswine.

SW'99	Final

Raticate has a slightly different footprint, with it incorrectly showing a four-toed foot instead of a three-toed one.

SW'99	Final

Mew has a slightly different footprint, with it being slightly longer than in the final game.

SW'99	Final

Murkrow has a slightly different footprint, with it showing a three-toed foot instead of a four-toed one. Interestingly, as can be seen in Murkrow's Spaceworld '97 design as well as its Spaceworld '99 Silver sprite, Murkrow was originally intended to only have two front toes instead of three like it does in the final game. The footprint graphic was updated in the final game to reflect the updated foot design.

Pokédex Entry Changes

To do: Document the differences.

Almost all of the dex entries are different in this build of the game:

Pokémon	Demo Entry (Gold)	Demo Entry (Silver)	Final Entry (Gold)	Final Entry (Silver)	Notes
Bulbasaur	JP DEMO GOLD ENTRY	JP DEMO SILVER ENTRY	JP FINAL GOLD ENTRY	JP FINAL SILVER ENTRY	NOTES.
