Editing An Absolute Beginner's Guide for the RP2 (section)

=== Downloading and switching to RetroidOS ===

From the main Android home screen, use the d-pad to select the middle icon at the bottom of the screen, which looks like a circle with six dots inside. Then press the "A" button to confirm. This will open the Android app drawer, which is a menu of all the apps installed in Android on your RP2.

Now that you're in the app drawer, use the d-pad to move the square highlight until it is on the "Toolbox" app. Because there will be more apps installed on your RP2 than can fit on the screen at once, you will probably need to scroll the app drawer a little before you will be able to see the "Toolbox" app. Just keep moving the highlight down, even after you reach the bottom of the screen. The app drawer will scroll automatically to keep up. Once the icon is highlighted, press "A" to open the "Toolbox" app.

Inside the "Toolbox" app, use the d-pad to select the "Install Retroid Pocket app" option, and press the "A" button to confirm. As long as your Wi-Fi connection is working, your RP2 should connect to the Retroid servers, and then download and install the "Retroid" app for Android. When it has finished, it will display a message to let you know that the installation is complete. Now exit the "Toolbox" app by pressing the "HOME" button to return to the Android home screen.

Open the app drawer again, and use the d-pad to select the new "Retroid" app icon, then press the "A" button to confirm. A window will pop up to ask if you really want to switch to Retroid OS; press the "A" button to confirm. Your RP2 will shut down and then automatically restart in RetroidOS mode. Once again, it will take 30 to 40 seconds to boot up, so you will need to be patient.

Congratulations! Your RP2 will now boot directly into RetroidOS every time you turn it on, and you should never need to touch Android again unless you want to.

The "Retroid" app in Android acts kind of like a key to the encrypted files that came on your included 32GB micro SD card. When you run it, it reconfigures your RP2 to boot from the encrypted files on the micro SD card, and then reboots itself. Once that happens, Android is no longer running, and nothing is shared between your Android internal storage (e.g. apps or any games you store there) and RetroidOS (including the games that you install within it).
