File Associations

Pico Launcher supports custom file associations for file extensions other than .nds. By setting up a file association, files with the specified extension will be opened using the specified DS application. The file path is passed via argv.

How to setup file associations

1. Open /_pico/settings.json.
2. If not present yet, add a fileAssociations key.
3. For each file association add a key inside the fileAssociations key. For example:

   "fileAssociations": {
     "xyz": {
       "appPath": "/path/to/xyz/app.nds"
     },
     "gba": {
       "appPath": "/myGbaApp.nds"
     }
   }
   

   With this setup .xyz files will be opened by /path/to/xyz/app.nds and .gba files will be opened by /myGbaApp.nds.
