Pokémon

This is a sub-page of Proto:Pokémon Gold and Silver/Spaceworld 1997 Demo.

Despite only being a demo, this build of the game contains data for 251 Pokémon: the returning original 151 as well as 100 newcomers. While only a handful are obtainable through the demo, all of them have front and back sprites, names, typing, and the like. 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.

Pokédex#

The final games have a handful of Pokémon menu sprites changed in relation to this demo, including some newly designed ones not yet implemented as of this build. Said missing menu icons are marked with an asterisk (*) in the following tables.

Original 151#

All of the original 151 Pokémon received brand new sprites, with both front and back sprites being completely original. Interestingly, many of the front sprites come from the Japanese release of Pokémon Blue. This is due to both Blue and Gold and Silver being developed side by side with Blue being completed first and ultimately making use of these sprites first. The back sprites seen here are exclusive to this build, with a lot of them based off the Blue front sprites. Blue and Yellow reused the original Generation I sprites; this was likely a space or memory-saving measure as the original back sprites have significantly smaller file sizes. While Generation I back sprites are stored at half size, these back sprites already follow the same design philosophy as the final Gold and Silver ones, with them being drawn in full resolution.

Another thing worth noting when it comes to the relationship between this build of the games and Pokémon Blue is that the former shares the latter's changes made to Nidoqueen and Geodude's weights, as well as Porygon's Pokémon category. The category change and Nidoqueen's corrected weight would go on to be featured in the final versions of Gold and Silver, whereas Geodude's decreased weight was reverted in Japan starting with Yellow in 1998.

Demo 152-251#

The 100 new Pokémon introduced in this prototype, of which only 60 were officially released as part of Generation II, with 29 of those released Pokémon undergoing anything from minor to major design revisions before the final releases. Also note that while somewhat organized, the order in which these Pokémon appear in likely reflects some sort of internal index. The final incarnation of these Pokémon (if known) will be provided for comparison.

Base Stats#

Data Structure#

The data structure is 31 bytes long, compared to Generation I's 28 bytes, and the final Generation II games' 32 bytes. The base stats data table is in Pokédex order (starting with Bulbasaur), and begins at address 0x50f10. The demo lacking the egg groups byte reveals that while breeding had already conceived, it had yet to be actually implemented.

Other than that, the data structure is essentially the same as the final Gold and Silver one, with the only remaining difference is that the final table lacks the address of the front and back Pokémon sprites for the Pokémon, unlike Generation I and this demo. Interestingly enough, however, the final table does have a zero-filled four-byte section where these addresses were.

Original 151#

Of the 151 returning Pokémon, 95 of them received changes to their Special Attack or Special Defense between the demo and the final version. In general, Pokémon have higher Special Attack and lower Special Defense in the final version. The Bellsprout, Magnemite, and Tangela evolutionary lines received the most drastic changes.

The Pokémon's demo stat is listed first, and its final stat is listed second.

Demo 152-251#

All of the new Pokémon have a placeholder catch rate of 255, along with a base experience of either 100 or 64, and many of them use 50s as a placeholder. They virtually all share a Medium Slow growth rate, with the only exceptions being Crobat, Slowking, and Elekid, which have a Medium Fast rate. The entirety of the new roster is assigned the same TM flag data, with them being able to learn TMs 1, 5, 6, 8, 9, 10, 11, 12, 13, 14, 15, 17, 18, 19, 20, 22, 24, 25, 29, 30, 31, 32, 33, 34, 35, 36, 38, 40, 44, 45, 46, 49, 50, 54, and 55.

Interestingly, some stats appear to have been cloned from Gen 1 Pokémon during development, with the SpD dummied out.

Slowking and Politoed's stats were cloned from Slowbro and Poliwrath respectively.
Rai and En's stats were cloned from Zapdos and Moltres.
Sui appears to use a previous revision of Articuno's stats, with the Special Attack still being 125 from before it was swapped.

Gender Ratios#

Despite gender having been implemented, it is still in a visibly early state. Namely, only the 50/50, purely Male, purely Female, and Gender Unknown ratios have been implemented, and even there differences are abound. Unless specified, the Pokémon mentioned below use the default 50/50 ratio:

The starter, Eevee, Kabuto, Omanyte, Aerodactyl, and Snorlax lines were ultimately given the 87.5 Male/12.5 Female ratio.
The Growlithe, Abra, Machop, and Magby lines, as well as Electabuzz, were ultimately given the 75 Male/25 Female ratio.
The Cleffa, Vulpix, Wigglytuff, and Igglybuff lines were ultimately given the 25 Male/75 Female ratio.
The Tauros line, as well as Tyrogue and Hitmontop, were ultimately given the Male Only ratio.
The Chansey, Smoochum, and Miltank lines were ultimately given the Female Only ratio.
The Staryu, legendary birds, Mewtwo, Mew, Unown, Porygon2, legendary beasts, and Ho-Oh lines were ultimately given the Gender Unknown ratio.
Elekid is Male Only and Snubbull is Female Only, while in the final games they were ultimately given the 75 Male/25 Female and 25 Male/75 Female ratios respectively.
Interestingly enough, the scrapped Pokémon Rinrin is Female Only, but its evolution, Berurun, has a 50/50 ratio.

Evolutionary Requirements#

The various ways in which Pokémon which did make it into the final games can evolve in this prototype. Evolutionary stones work as intended, except for the newly introduced Soul and Poison Stones. Happiness-related evolutions don't yet exist at this point of development, whereas all items necessary for a trade evolution are functional.

Interestingly, the demo uses a rather odd, possibly placeholder evolution method for Tyrogue, where it evolves into Hitmonlee upon reaching level 15, then immediately proceeds to evolve into Hitmonchan, and then Hitmontop right after. The evolution can be stopped at any point, thus letting you choose which Pokémon you want, albeit in a somewhat clumsy fashion. If left untouched, you will end up with a Hitmontop, though all three Hitmons will be recorded in the Pokédex. Meanwhile, Eevee evolving via a Leaf Stone was ultimately implemented into Generation VIII as the way to obtain Leafeon, due to the lack of a Moss Stone in those games.

It's also worth noting that here, Quagsire, Marill, Sunflora, Togepi, and Snubbull are all single-stage Pokémon. This is due to Wooper, Azumarill, Sunkern, Togetic, and Granbull being missing from this build of the games.

Cries#

While all Generation I Pokémon make a return with their proper cries, the newly introduced Pokémon mainly use placeholder cries, though a few unique ones do exist.

Shinies#

Shiny Pokémon already exist in this build, albeit in a rather rudimentary form. Unlike in the final games, the DV requirement for shininess is simply to have 10 or higher in each non-HP stat, yielding an appearance rate of 81/4096 or ~1.977% (considerably higher than the final's rate of 1/8192). Upon encountering one in the wild, no special animation will play out; the proper send-out animation used for shiny Pokémon in the final games is actually implemented, but for some reason it is only assigned to non-shiny Pikachu and Sunflora.

Due to this build being for the Super Game Boy as opposed to the Game Boy Color, the array of colors available is incredibly limited. As such, in addition to the 10 Pokémon palettes returning from Red and Green, another 10 were added as their shiny equivalents. Thus, all Pokémon of a given palette also share the same shiny coloration.

Color	Standard Palette
Green	0xE7E7E7	0xA7D787	0x4FA75F
Orange	0xE7E7E7	0xFFA757	0xD75737
Cyan	0xE7E7E7	0xAFCFEF	0x779FCF
Brown	0xE7E7E7	0xE7A77F	0xAF774F
Yellow	0xE7E7E7	0xFFE777	0xD7A707
Blue	0xE7E7E7	0x97A7DF	0x5F7FBF
Purple	0xE7E7E7	0xDFB7C7	0xAF7FBF
Human	0xE7E7E7	0xF7B78F	0x87779F
Faded	0xE7E7E7	0xD7AFB7	0x7F7F97
Pink	0xE7E7E7	0xF7B7C7	0xE77FAF

Oddly enough, the shiny palette applied to pink Pokémon has the lighter pink turned to a baby blue, while the darker pink becomes the same shade as the lighter one. This improper palette causes the sprites to which it is assigned to look messed up, and so it's likely that this second shade was instead supposed to be a darker shade of blue, as seen below:

Standard	Shiny (Normal)	Shiny (Mock-up)
