Major discoveries revealed from Pokémon Gold and Silver demo

Files from the Spaceworld 1997 and 1999 demo versions of second generation games, Pokémon Gold and Silver, have surfaced today. Sprites of scrapped and earlier versions of Pokémon have appeared.

We are currently opting not to show images, as various websites (such as gssource.neocities.org) and Twitter users have been recently informed to pull such content by Nintendo or The Pokémon Company.

In order to avoid getting BTFO’d by Nintendo lawyers, I have removed the sprites from the 24.04.2020 source code dump.

I was not, and will not be, distributing the source code leak. If you would like to confirm it for yourself, I’m afraid I cannot help you. What was originally hosted on here was only images of the front sprites, back sprites, and trainer sprites; as well as a few pages on interesting unused functions and music. I was not the leaker, nor did I have ties to whomever posted the source code.

Thank you to the community for helping dig through and help these old unused Pokémon sprites see the light of day.

Statement:

After a phone call just now, I’ve decided to delete some tweets I made earlier today. If you look around, you’ll see others doing the same. I’ve never done this before, but it’s for the best. I think I’ll spend the rest of the day playing Animal Crossing with my cats. pic.twitter.com/omG5EBtmyf

However, sources listed below show some of this content, and are linked to.

Highlights include:

Evidence Cyndaquil was its own species line and not originally intended to be the Fire Starter (in line with the previous leaks we reported on).
Japanese Pokédex entries for various Pokémon exist.
Generation 2 versions of Komala and Cherrim have been spotted.
Dunsparce had two different designs, while others such as Wooper looked fairly different.
Natu was a 3-stage line.
Celebi had quite a different look as well, and was a Normal type.
Placeholder sprites were used, such as for Larvitar and Wobbuffet.
Kingdra’s beta design was pretty cool looking.
The Elite Four had the likes of Agatha, Lorelei, and… Giovanni.
Some line-ups of Trainers had changed, including Falkner having Pidgey, Pidgeotto and Pidgeot at level 10 (the filthy cheater).
Music was unfinished, such as a few areas using an earlier version of the Bicycle theme, and Kanto using generation one versions as placeholders.
Evidently the game changed a lot between the Spaceworld 1999 demo release and full game release – which was only a gap of about three months!
