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

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

While the Pokédex is starting to match the one seen in the final games, there are still plenty of unusual differences to note. Several Johto Pokémon also use placeholder sprites (or even leftovers from the Spaceworld '97 demo) and/or cries. Speaking of sprites, it is clear that Silver having its own unique sprites was a relatively recent addition, given how virtually all of them are unfinished. Moreover, a couple of sprites here clearly use SGB ("Spaceworld 1997-style") shading, which tell us that some of those sprites were older assets being reused, with some of them ultimately being redrawn for the final game.

For the sake of accuracy, the "Final" sprites shown here 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, the full details of which can be seen here.

The fact Wobbuffet has design similarities to the various Tsuinzu incarnations, in addition to sharing their Dex spot, and Psychic type suggests that Tsuinzu was reworked into Wobbuffet. Uses the Rhydon menu icon instead of the Gengar icon.
203	Girafarig									キリンリキ Kirinriki	Gold sprite matches final. Silver is similar, but lacks refining.
204	Pineco									クヌギダマ Kunugidama	All sprites were refined for the final games. Uses the quadruped menu icon instead of the 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 games. 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 classical depictions of the Tsuchinoko. Lacks the wings and drill tail, and the blue stripes are instead small black spots. 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 final.
208	Steelix									ハガネール Haganeeru	Gold sprite matches final. Silver is similar, but lacks refining.
209	Snubbull									ブルー Buruu	Both its front sprites have white collars instead of blue. Gold sprite almost matches final, albeit with some minor alterations to the face. Silver is similar, but lacks refining.
210	Granbull									グランブル Granbull	Gold sprite matches final. Silver has a completely different pose.
211	Qwilfish									プクー Pukuu	Gold sprite is reused from the Spaceworld 1997 demo. Silver is similar, but lacks refining. Still uses its early name, "Pukuu", from the Spaceworld '97 demo.
212	Scizor									ハッサム Hassamu	Gold sprite matches final. Silver has a completely different pose.
213	Forretress									プラックス Purakkusu	Gold sprite is only a basic outline at this point. Silver is a duplicate of the Gold one. Uses the name and backsprite of of the scrapped Pinsir evolution from Spaceworld '97. Forretress' Dex number is 205 in the final games, while Shuckle is the one occupying 213.
214	Heracross									へラクロス Heracross	Gold sprite matches final. Silver is similar, but lacks refining.
215	Sneasel									ニューラ Nyuura	Both sprites makes use of a slightly more refined version of Sneasel's more overtly Kamaitachi-like design from the Spaceworld 1997 demo, albeit with the Gold sprite missing its tail. Despite the updated front sprites, the backsprite is reused from the Spaceworld '97 demo.
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 has a completely different pose. Backsprite is similar to final, but was refined. All sprites use a yellow palette as opposed to a light brown one.
217	Ursaring									リングマ Ringuma	Both sprites match final.
218	Magcargo									マグマッグ Magumaggu	Both sprites have similar poses, but lack the shell flame and lava bubbles, have smaller, cross-eyed eyes, and have 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 Rhydon menu icon instead of the slime icon. Slugma occupies this Dex spot in the final games, while Magcargo was moved to spot 219.
219	Corsola									みてい08 Mitei 08	Gold sprite matches final. Silver is a duplicate of the Gold one. Uses the placeholder "Mitei" name. Uses the backsprite and typing of the Mr. Mime pre-evolution from Spaceworld '97. Uses the Rhydon menu icon instead of the shell icon. Corsola's Dex number is 222 in the final games, while Magcargo is the one occupying 219.
220	Swinub									みてい09 Mitei 09	Both sprites match final. Uses the placeholder "Mitei" name. Uses the Rhydon menu icon instead of the quadruped icon.
221	Piloswine									イノムー Inomuu	Both sprites match final.
222	Slugma									みてい10 Mitei 10	Gold sprite has different, more stereotypical "slug eyes", in addition to lacking the magma-themed bubbles and "drool" seen in the final sprite. Silver is a duplicate of the Gold one. Its backsprite is very crude and unrefined. Uses Magcargo's height, weight, palette, while using the "Mitei" name. Uses the quadruped menu icon instead of the slime icon. Corsola occupies this Dex number in the final games, while Slugma was moved to 218.
223	Remoraid									テッポウオ Teppouo	Similar poses to final, but still using 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 is similar to final, though it also features the "June 1999" design. Back sprite is the same as the June 1999 one, albeit with updated shading, unlike the front sprites, which still use Spaceworld 1997-style shading. Still uses its early name, "Gift", from the '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 Gold sprite depicts these "Remoraid" with a face. Uses the bird menu icon instead of the Magikarp icon.
227	Skarmory									ヨロイドリ Yoroidori	Both sprites match final. Still uses its early name, "Yoroidori", from the Spaceworld '97 demo.
228	Houndour									デビル Debiru	Gold sprite matches final. Silver almost matches final, but was refined. Still uses its early name, "Debiru", from the Spaceworld '97 demo. Backsprite almost matches 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 final. Silver is similar, but lacks refining.
230	Kingdra									キングドラ kingudora	Gold sprite and backsprite are reused from the Spaceworld '97 demo. Silver sprite has a completely different pose, and still uses Kingdra's early design. Has a different, duller palette. 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 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 final. Silver is similar, but lacks refining.
233	Porygon2									ポリゴン2 Porygon2	Gold sprite and backsprite almost match the final, albeit with some shading differences. Silver almost matches final, but was refined.
234	Stantler									オドシシ Odoshishi	Gold sprite matches final. Silver is similar, but lacks refining.
235	Smeargle									ドーブル Dooburu	Gold sprite matches final. Silver is similar, but lacks refining. Uses the Animal menu icon instead of the Rhydon icon.
236	Tyrogue									ゴング Gongu	Gold sprite and back sprite are reused from the Spaceworld '97 demo. Silver also uses the Spaceworld '97 design, and features a different pose which may have been inspired by Hitmonchan's Gold sprite. Uses the Humanoid menu icon, instead of the Machoke icon. Has a different, tackier palette. 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 has a completely different pose. Has a different, tackier palette, which is reused from Tyrogue. Uses the Humanoid menu icon, instead of the Machoke icon.
238	Smoochum									キスキス Kisukisu	Gold sprite almost matches final, albeit with some shading differences. Silver almost matches 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									エレキッド Elekid	Gold sprite matches final. Silver is similar, but lacks refining.
240	Magby									ブビィ Bubii	Gold sprite is similar to final, but was refined. Silver matches final.
241	Miltank									ミルタンク Miltank	Gold sprite is reused from the June 1999 folder, and the back sprite is an updated version of the one from Spaceworld 1997 demo, only with touched-up shading. Silver has a completely different pose.
242	Blissey									ハピナス Hapinasu	Both sprites match final.
243	Raikou									ライ Rai	Gold sprite almost matches final, albeit with Raikou's fangs being red and much longer than they are in the final games. Silver uses the early design and has a completely different pose, whereas in the final games, both versions share the same sprite. Backsprite is completely different. Still uses its early name, "Rai", from the Spaceworld '97 demo.
244	Entei									エン En	Gold sprite almost matches final, albeit with Entei sporting a larger tuft of fur in the front. Silver uses the early design and has a completely different pose, whereas in the final games both versions share the same sprite. Still uses its early name, "En", from the Spaceworld '97 demo.
245	Suicune									スイ Sui	Gold sprite matches final. Silver uses a completely different pose, whereas in the final games both versions share the same sprite. Still uses its early name, "Sui", from the Spaceworld '97 demo.
246	Larvitar									ヨーギラス Yoogirasu	Gold sprite has a completely different pose and is very clearly unfinished. Silver is a duplicate of the Gold one. Only a basic outline has been drawn at this point. Uses a shrunken-down version of Tyranitar's backsprite as its own.

Silver is a duplicate of the Gold one. Uses the placeholder "Mitei" name. Uses the Rhydon menu icon instead of the Humanoid icon. It also has a different species name, and uses a placeholder typing, as well as a different, brown palette.

New Pokédex Differences

While the "Old" Pokédex mode (also known as "National Dex") already features some differences, the "New" mode (or "Regional Dex") deviates even more from its final counterpart. The only exceptions are the starters, and the very last chunk of the dex, with Pokémon ranging from Chansey to Celebi.

Pokémon Dimensions

Some of the Pokémon in this prototype are assigned a different height and weight when compared to final games, in some cases reflecting earlier designs.

Pokémon	Early	Final
Ariados	0.9 m 33.5 kg	1.1 m 33.5 kg
Crobat	2.1 m 75.0 kg	1.8 m 75.0 kg

Pokémon Species

Some of the Pokémon in this prototype use different species names when compared to final games.

Pokémon	Early Species	Final Species	Notes
Ledian	ななつぼし Seven Star	いつつぼし Five Star	Only has five spots, though with its wings deployed it does appear to have seven of them, as one gets cut in half.
Crobat	エックス X	こうもり Bat	Crobat was known as "エクシング" (X-ing) in the Spaceworld 1997 build of the games, hence the different species name. Was ultimately given the same category as Zubat and Golbat.
Politoed	かわず Frog	かえる Frog	Uses a different, less common term for "frog".
Wobbuffet	シャドー Shadow	がまん Endurance	Wobbuffet was originally a Girafarig pre-evolution named Tsuinzu, as seen in the Spaceworld 1997 build of the games, hence the different species name.
Shuckle	やきも Pottery	はっこう Fermentation	Originally had a more vase/pot-like shell, hence the different species name.
Sneasel	いたち Weasel	かぎづめ Claw	Originally looked more like a weasel, hence the different species name.
Piloswine	いのぶた Pig-Boar	いのしし Wild Boar	Reuses Swinub's species name.
Remoraid	ジェット Jet	ふんしゃ Propulsion	Uses a different term for jet.
Octillery	ジェット Jet	ふんしゃ Propulsion	Uses a different term for jet.
Suicune	あまのがわ Milky Way	オーロラ Aurora	The Japanese term for "Milky Way" is "Heavenly River", meaning that its wavy tail was originally meant to evoke the flow of water. In the final games, this was changed to the undulating form of an aurora borealis.
Celebi	プラント Plant	ときわたり Time Travel	It appears to have already been envisioned as a Pokémon which has a relationship with nature. In this build of the games, however, it uses the Normal type as a placeholder.

Footprints

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

This placeholder graphic can be seen used in the Pokédex entries for Chinchou, Azumarill, Sunkern, Wobbuffet, Corsola, and Celebi. In the final games, all these Pokémon were given their own unique footprint with the 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 games (or in 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 games (or in 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 games (or in 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 of Tsubomitto, reusing its name, typing, and back sprite, while Tsubomitto itself was still in the games' Pokédex as of June 1999, making it clear it had received a footprint of its own by then. In the final games, Lanturn doesn't have a footprint.

The footprint used by Forretress, meanwhile, appears to have been intended for Purakkusu, as it matches the general shape of its feet. This makes sense as Forretress was built off Purakkusu, reusing its name and back sprite, while Purakkusu itself was still in the games' Pokédex as of June 1999, making it clear it had received a footprint of its own by then. In the final games, Forretress doesn't have a footprint.

The footprint used by Wooper 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 still in the games' Pokédex as of June 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 games, despite having totally different feet. This oversight would later be fixed in subsequent games.

Piloswine	Slugma

Interestingly enough, the Spaceworld '99 version of Slugma (known there as "Mitei 10") uses a footprint which appears to be a larger version of the one used by Piloswine. This is due to Slugma having been built off of a short-lived cut Piloswine evolution, as seen by Piloswine evolving into it starting at Level 30. This is further seen by it also using the "Quadruped" menu sprite and the Ice/Ground typing, much like Swinub and Piloswine.

In the final games, Slugma doesn't have a footprint. Piloswine wouldn't get an evolution until Generation IV, in the form of Mamoswine.

SW'99	Final

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

SW'99	Final

Mew has a slightly longer footprint than in the final games.

SW'99	Final

Furret has a slightly shorter footprint than in the final games.

SW'99	Final

Marill has a slightly longer footprint than in the final games.

SW'99	Final

Murkrow has a slightly different footprint, showing a two-toed foot instead of a three-toed one. This matches Murkrow's design in the Spaceworld '97 build and Spaceworld '99 Silver one. The footprint graphic was updated in the final games to reflect the updated foot design.

SW'99	Final

Sneasel has a radically different design, namely with it featuring three toes instead of just two, as seen in its early design.

Evolutionary Requirements

Unlike the Spaceworld 1997 build of the games, this prototype does feature all the Pokémon seen in the final games. However, a handful of them were quickly built upon scrapped Pokémon, leaving a few entries with the sprite of one Pokémon, but the name and other data of another. This leaves Chinchou, Quagsire, Magcargo, and Pineco as single-stage Pokémon, due to Lanturn, Wooper, Slugma, and Forretress all retaining leftover evolutionary data. Sunkern also lacks an evolution method altogether, due to it then being a recent addition (as evidenced by its placeholder name, typing, and sprites).

Pokémon Types

A handful of Pokémon still have different types, mainly due to them being either placeholders or leftovers.

Pokémon	Early Typing	Final Typing	Notes
Chinchou	Normal	Water/Electric	Uses the Normal type as a placeholder.
Lanturn	Grass/Poison	Water/Electric	Reuses the typing of Tsubomitto.
Sunkern	Normal	Grass	Uses the Normal type as a placeholder.
Wooper	Normal/Flying	Water/Ground	Reuses the typing of Madame.
Misdreavus	Ghost/Dark	Ghost	Reuses the updated typing of Norowara.
Wobbuffet	Normal/Psychic	Psychic	Reuses the typing of Tsuinzu.
Pineco	Grass	Bug	Has a completely different typing.
Shuckle	Rock/Ground	Bug/Rock	Its Ground typing was replaced with the Bug typing.
Slugma	Ice/Ground	Fire	Reuses the typing of the scrapped Piloswine evolution.
Corsola	Normal	Water/Rock	Either reuses the typing of Baririina, or uses the Normal type as a placeholder.
Ho-oh	Normal/Flying	Fire/Flying	Uses Normal instead of Fire as its first type.
Celebi	Normal	Psychic/Grass	Uses the Normal type as a placeholder.

Cries

Unsurprisingly, some Pokémon cries are not yet finalized, with pitch differences and even some placeholders here and there.

Placeholder Cry

A placeholder cry returning from the Spaceworld '97 build of the games. Used here for Chinchou, Sunkern, Magcargo, Corsola, Pupitar, and Celebi.

Palettes

Unsurprisingly, most Pokémon had their palette finalized by the time this demo was compiled, with the only few outliers being the handful of Johto Pokémon which still had to be finalized. Namely, Furret, Azumarill, and Wobbuffet all reuse the palette of the Pokémon they overwrote (in that case, Gyopin, Hinaazu, and Tsuinzu respectively). As for the Slugma line, its case is a bit special, as Slugma and Magcargo pretty much swapped everything with one another, which also relates to their color schemes, with the latter originally being orange, and the former being pink (the exact same palette as the one used by Magcargo in the final games).

Shinies

Virtually all shiny Pokémon have been finalized by now, though a few outliers still remain. Interestingly, it's worth noting that Oddish, Gloom, Sunkern, Murkrow, Dunsparce, Corsola, Larvitar, and Pupitar all lack an actual shiny palette, as the one they are assigned to just consists of their base colors. This also happens to Azumarill, whose base palette was coincidentally later repurposed as its shiny palette. Magcargo, meanwhile, is rather interesting, as it is assigned Slugma's final shiny palette and vice-versa.

Pokémon	Early Palette				Final Palette				Sprite
Chansey	0FFFFFF	0x5048F0	0xF050B0	0x000000	0xFFFFFF	0xD8C898	0x689808	0X000000
Chinchou	0FFFFFF	0x7070D0	0x3838A0	0x000000	0xFFFFFF	0xB0E060	0x6070A0	0X000000
Wobbuffet	0FFFFFF	0xE000E8	08048E0	0x000000	0xFFFFFF	0xB838C8	0x384880	0X000000
Ho-Oh	0FFFFFF	0xE8B000	0xE06800	0x000000	0xFFFFFF	0xC8A000	0xF84020	0X000000
Celebi	0FFFFFF	0x98F860	0x48B008	0x000000	0xFFFFFF	0xF87878	0x782090	0X000000

Oddly enough, the shiny palette assigned to Chansey has the lighter pink turned to a deep blue, while the darker pink stays the same. This improper palette causes the sprites to look messed up, and so it's likely that the darker pink was instead supposed to become blue, as seen below:
