pokemon-yellow-typescript is a browser game that recreates Pokémon Yellow in TypeScript. It runs in your web browser and pulls game data from your own ROM. This keeps the game close to the original while letting you play on a modern PC.
It is built for Windows users who want a simple way to open the game and start playing without a hard setup process.
Use this page to download or open the project:
- Open the link above.
- On the GitHub page, look for the latest files or release assets.
- Download the file that matches the app or build you want to use.
- If the file comes as a ZIP, right-click it and choose Extract All.
- Open the extracted folder.
- Double-click the main HTML file or app file to start the game in your browser.
If your browser asks for permission to open local files, allow it so the game can load.
This app works best on a Windows PC with:
- A modern browser such as Chrome, Edge, or Firefox
- A recent version of Windows 10 or Windows 11
- A copy of your own Pokémon Yellow ROM
- Enough free disk space for the game files and browser cache
For the best result, use a desktop browser rather than a phone browser.
Follow these steps to get the game running:
- Download the project from the link above.
- Get your own Pokémon Yellow ROM ready.
- Place the ROM file in the folder the app expects, or choose it when the game asks.
- Open the game in your browser.
- Wait for the data extraction step to finish.
- Start a new game or load your session if the app offers that option.
The first launch may take a little longer because the app reads data from the ROM and builds the game files it needs.
Once the game is open, use your keyboard like you would in other browser games:
- Arrow keys: move around
- Enter or Z: confirm
- Backspace or X: cancel
- Space: open extra actions in some screens
If the game uses a gamepad, plug it in before you start and open the control settings in the browser if needed.
- Runs in the browser
- Rebuilds Pokémon Yellow in TypeScript
- Uses your own ROM for data extraction
- Keeps the classic pixel art look
- Works well on Windows
- Loads like a web game
- Fits the feel of the original Game Boy release
- Built for fans of retro gaming and Gen 1 Pokémon
This project does not ship with game data. It reads the data from your own Pokémon Yellow ROM and uses that to recreate the game in the browser.
That means the app can:
- Pull maps, sprites, and battle data from your ROM
- Reuse original game data
- Keep the game close to the source material
- Avoid extra setup once the ROM is in place
If the game does not start, check that the ROM file is valid and that the browser can access it.
If you use Windows, these steps can help:
- Use Edge or Chrome for the smoothest run
- Keep the game folder in a simple path, like
C:\Games\pokemon-yellow-typescript - Avoid spaces or special characters in file names if the app has trouble finding the ROM
- Turn off browser pop-up blocks if the game opens a local file window
- Keep your browser up to date
If the page does not load, try opening it from a fresh browser window.
These are the common controls for this kind of browser game:
- Move: Arrow keys
- Talk / Select: Enter or Z
- Back / Cancel: X or Backspace
- Menu: Enter or Space
- Reload page: Ctrl + R if the game freezes
If the project includes on-screen controls, use those as well.
A simple folder layout can make things easier:
pokemon-yellow-typescript/- game files
- ROM file
- save data
- browser assets
Keep the ROM in the same folder as the app if the project expects that. If the app has a file picker, select the ROM from that folder.
- Check that you opened the correct file
- Try a different browser
- Make sure the download finished
- Extract the ZIP before you run it
- Reload the page
- Clear the browser cache
- Close other tabs
- Try Chrome or Edge
- Confirm that the ROM file is in the right place
- Check the file name
- Select the file again if the app shows a picker
- Turn up the volume in Windows
- Check the browser tab sound icon
- Refresh the page after you allow audio
- Close other apps
- Use a newer browser
- Try a full-screen window
- Keep hardware acceleration on in your browser settings
