Im trying to explain how it works and upload a "beta" version.
Yo need to create a folder called "fade_in" inside the "modules" folder.
And another folder inside this new one called "media".
Then add this lines at the end of each layout.nut you want to "fade_in"
//
// Fade_in Module
//
fe.load_module("fade_in/fade_in.nut")
So inside the "modules/fade_in/media" folder copy your rocketlauncher "Fade" folder.
Usually contents a "_Default" folder and system folders like "Atari 2600" , "Atari 5200"
You need to rename this folders to match your "emulator names"
Check this lines:
...fe.add_image("/home/pi/.attract/modules/fade_in/media/_Default/Layer 1.png"
At this moment I cant get the "module" to work with relative paths , so I set the complete path of my rpi.
If you want to try on another system you will have to change all this lines.
