This is a script you can run in your browser to download the scenes’ text file from a game hosted at DashingDon or Cogdemos.ink.
Do no evil!
This is an honor-based system:
- Do not use this script to keep illegal copies of games.
- Do not use it on games whose author has requested not to peek into their code.
- Preferably, use the script only on your own games or on those whose author has granted explicit permission.
Observations
- The script only automatizes something that is already possible to do manually.
- The script will not download game assets, such as images and audio files.
- It won’t work on compiled games.
Reasoning
Personally, when giving feedback on typos or awkward wording I like to be specific, pointing out the file name and if possible the code line. This means I’m constantly peeking into others’ code.
- Easily reclaim your own lost game that only exists on DashingDon or Cogdemos.ink.
- Easily access game files to study someone else’s code (code diving).
Installation
These instructions are for Chrome. However, they should be similar for other browsers.
- Open the
Bookmark Manager. - Create a new bookmark manually.

Whenever you’re in a game’s page on DashignDon or Cogdemos.ink which you wish to download the text files, just click the bookmark you created and the script will fetch and zip all files for you.
