To add double-click support to Graal levels (Win95/98: not sure about XP, but the process is probably pretty similar):
- Open My Computer.
- Open up the View menu.
- Click "Folder Options...".
- In the dialog box that appears, click on the File Types tab.
- Click New Type.
- Make the "Description of Type" Graal Level and make the "Associated Extension" .graal
- For the Actions, click on "New..".
- Make the Action name "Open", and the "Application used to perform action" C
(path to your Graal folder)\Graal.exe "%1", for example: CGames\Graal2001\Graal.exe "%1"
- If you like, click Change Icon to give your new type an image. It should take a Graal image by default, though.
- Click Close to save your new file type.
- Repeat the process, but make the "Description of Type" 'Graal NewWorld Level' and the Associated Extension .nw
- You're done.
