You can read directions in the Bliss iPhone app by going to Help > Game Options > Adding Custom Files. It mentions that there are two ways you can go about it:
Adding Files Via Email
- Email your files as attachments to an account that you can access on your device’s Mail app.
- Open the Mail app on your device and select the email.
- Find the attachment you want to send to Bliss and tap on it.
- Tap Open in “Bliss”
Adding Files Through iTunes
- Make sure your device is connected to your computer and open iTunes.
- Select your device in iTunes’ sidebar and click the Apps header in the main view.
- Scroll down to the File Sharing section and select Bliss in the Apps list.
- Drag the files you want to add onto the Bliss Documents list, or click the Add... button to browse for your files.
In order to follow these steps, however, you need to know where to find the action files to copy over. The location varies depending on which operating system you're running:
- For Windows XP navigate to C:\Program Files\Games for Loving\Bliss 1.6.
- For Windows Vista or Windows 7 navigate to C:\Program Files (x86)\Games for Loving\Bliss 1.6.
- For Mac OSX right-click or control-click on the Bliss application and choose Show Package Contents. Then navigate to Contents/Resources/Java.
Once you're at that location you can find the action files in the Actions folder and any profiles you've created in the Profiles folder.
