Introducing: Pokémon Brown 3D!

Almost 3 years in the making, Pokémon Brown 3D is here at last!

This is a game mod for Pokémon 3D by Kolben Games (link here), enabling you to experience the storm of Pokémon Brown 20th Anniversary in a full 3D environment, originally starting as a fangame project by Leahkim and Miragics before being taken on by RainbowDevs.

Pokémon Brown 22nd Anniversary Stream!

Ever had a question for the developers? Now’s your chance to ask live! Today it’s 22 years since Pokémon Brown was first released, and to celebrate we will be joined by original developer Koolboyman and current lead developer Suloku to test the yet unreleased 6.2 update.

Merry Christmas from RainbowDevs!

We know it’s been very quiet lately, but we are still here and still ticking away. Development has slowed but it hasn’t halted; it’s mostly about finding the time to spare in our busy lives to work on Prism, and 2025 has been a very busy year for a lot of us.

Last Day of Pride Month!

We’ve been celebrating over on our Discord server with this wonderful icon created for us by Xe_cute!

It’s a Pokémon Brown Nuzlocke comic!

Check out these Pokémon Brown nuzlocke comics!! These are so awesome!!

Be sure to follow SammySami to find out what happens – they’ve been posting them daily!

A big thank you once again to our players for reporting issues on our report form and over on our Discord server. And of course, thank you so much for playing our game!

We all wish you a happy Christmas and wonderful new year!

Changelog: Version 6.1.2

Bugfixes

  • Mt. Boulder’s B1F static encounter NPC was hidden by mistake when TM14 was added. This prevented Pokédex completion in version 6.1.1.
  • The other player’s selected Pokémon at the trading selection screen was incorrectly displayerd.
  • The Pokéball icon when changing boxes wasn’t loaded from the start menu.
  • Azalea’s Gym still had some leftover hidden objects that could be accessed after getting the gift Pokémon.
  • Event at the final cave was being reset everytime the player beat the Rijon League.
  • A King’s Rock could be used on Politoed to evolve it into Politoed (old Brown leftover).
  • False Swipe Move tutor NPC has been moved to “fix” a collision issue in Azalea Town.
  • When beating the Elite 4, the blackout/teleport/dig/escape rope map was incorrectly set (normally it should be set to Seashore City). Blacking out or using teleport/dig/escape rope would end up on a glitched map.
  • There was an specific frame window for a Rocket in Final Island that could trigger a corrupted battle.

Move Changes

  • G.Weezing now learns Body Slam by TM.
  • Bulbasaur now learns Growth at level 29 instead of Growl.
  • Noivern at E4 knew Moonblast instead of Moonlight (Noivern can’t learn Moonblast).

New Features

  • Before releasing a Pokémon from the PC, a menu displays allowing to view the Pokémon’s stats, just like the withdrawn and deposit menus. This helps identifying Nicknamed or Shiny Pokémon before releasing.
  • Pokéballs can’t be used when the enemy Pokémon is Flying/Digging.

Graphics/Maps

  • Pokéball icons gfx for battle HUD, Pokédex and box swapping updated.
  • Silk Tunnel 1F had some wrong wall tiles near the hole that would connect to International Tunnel in Prism.
  • Tileset 0x0C (12) has been internally freed for future use if needed.
  • Minor changes to gate maps (i.e. added stools for the guards).
  • Johto gates graphics updated to be more similar to Gen 2.
  • Botan cave is now entered via a cave entrance instead of stairs.
  • Minor change to Castro Manor’s map: the eastern exit now goes to a new side dock in Castro Valley by the Manor instead of the Manor’s entrance.
  • Better background blending for stools and tables for lab tileset.
  • West entrance at the Rinjoh Peak gate is now only one tile, having a tree on the top half (same as all other horizontal gates in the game).
  • The “map” on the map house at Hayward now has a unique sprite instead of being a book.

Tweaks

  • Bugsy’s text slightly modified to clarify the 8th Gym Leader not being able to be rematched (Bugsy is the 8th rematch).
  • Wild encounters for Power Plant and Botan City Cave have been tweaked to increase the rare 1% encounters to 5%.
  • Tyrogue has been added as a 5% encounter to route 54 (previously only available as 1% encounter until post-game).
  • The girl at Hayward looking for her Slowbro now randomly turns around instead of just looking to her left.
  • Rocket at route 34 has had its engage distance reduced to 1.
  • The scientist NPC at Route 34 Gate now only moves left to right to prevent him going into the door.
  • Text has been added to the “notebook” on the table at the map house lady at Hayward City.
  • Minor text fixes.

Release: Pokémon Brown 6.1.1

Following our recent 6.1 release, have a hotfix! This has several important bugfixes, so if you have already updated to 6.1 we recommend you update to 6.1.1 as soon as possible.

This fixes a bug with the new laptop item and issues with the Pokédex. It also includes other tweaks that we didn’t have time to include in the 6.1 release.

Check out the full changelog here!

Remember to always back up your save data before attempting an update, and follow the instructions in the readme file that comes with the game.

Thank you to everyone who reported bugs in our Discord server and through our bug report form!

Changelog: Version 6.1.1

Note: the included data dumps in the previous 6.1 package file had incorrect information for some movesets and wild encounters.

Bugfixes

  • The new laptops glitched the game when changing boxes, with potential savegame corruption.
  • Pokédex saved page was being reset after trainer battles and bugged after entering Rijon League’s lobby.

Move Changes

  • Palette Black’s Honchcrow had two illegal moves.
  • G.Weezing now learns Double-Edge by TM.
  • Koffing, Weezing and G.Weezing now learn Take Down by TM.
  • Poliwrath now learns Dynamic Punch as evolution move instead of Submission (Submission can still be learned via the Move Relearner).
  • Crobat now learns Sky Attack instead of Poison Jab as evolution move (Poison Jab is still natually learned at level 32).
