Happy 20th Birthday Pokémon Brown!

A few days ago, Pokémon Brown turned 20 years old.

To celebrate, here is, for the first time, some video from the upcoming update!

Here you’ll see all-new features, such as an EXP bar, gender indicators, refreshed battle UI, new sprites and even more.

Stay tuned for more updates!

Pokémon Brown turns 20

Today, 20 years ago, I was in high school and released the very first version of Pokémon Brown. The first version was a mess in retrospect, built with a small map editor, “Tile Layer Pro” and a hex editor. but it broke grounds being the first finished “New Region” hack.

I could’ve never envisioned what ROM Hacking would’ve grown to 20 years later, the idea of modding games has grown so much, resulting in incredible passion projects. My contributions and the combined efforts of various talent since helped ROM hacks excel.

I encourage everyone to keep pushing forward, prove that your ideas are possible and continue to inspire the next generation, because the best is yet to come from ROM Hacks. I’m also still making stuff (the cartoon and a small game) and hope you like them when they’re out.

PSA: Pokémon Prism on Analogue Pocket

Hi everyone.

We’ve been getting an increasing number of bug reports regarding this issue and thought it a good idea to put this message out.

Players of Pokémon Prism on Analogue Pocket have been reporting save corruption issues. We have investigated and found the problem is with the Pocket itself, as software emulators and official hardware are unaffected. This issue can cause irreversible data loss and damage up to and including the loss of all Pokémon in your PC Box. This corruption remains even if you use the game pak on another console or boot it up in an emulator.

We would therefore advise players on Analogue Pocket to back up their save files immediately or, if playing on carts that cannot be backed up, stop using the console until Analogue issues an update to fix this bug. Official, non-Japanese Pokémon games do not appear to be affected, however, this may affect other Pokémon game mods like Prism.

Analogue should be able to fix this issue with an update to the console. We’ll let you guys know when or if that happens and when it is safe to play Prism on the console again. Hopefully soon.

Update (6 Dec): So far, we have only seen the issue affect cartridges. Methods like Everdrive, EZ-FLASH Junior and openFGPA so far do not be affected. However, we do still recommend backing up your save files frequently while using the console, as other issues may occur. An update to the Pocket is due soon – we will be testing this thoroughly and will report back. Please continue to report issues to us using our bug report form.

RainbowDevs Archive Launched!

Hello archival enthusiasts! If you’ve ever wanted to download an older version of our games, now you can in one convenient place. We’ve just launched the first phase of the RainbowDevs archive!

For now we have listed every RainbowDevs version of Pokémon Prism, but in the future we hope to expand to the pre-RD versions, as well as archival releases of our other games. We’re also making an effort to archive our data to the Wayback Machine, so should anything happen, you will always have access to a permanent, comprehensive arcive of all our games straight from the source.

Please note: these are old releases for troubleshooting and archival purposes only. They are not stable and have known issues, some serious, that may break or corrupt your sava data. We will not be providing support for these older releases, so, please use at your own risk.

Have fun!

It’s a Pokémon Brown update!
