Try out your programs
Now it's time to try out the programs you downloaded! Just make sure you're in the proper section (Game or Multimedia), as well as the proper folder/directory.
1) If you're in either the Game or Multimedia section and want to go back to the main menu, press the start button.
2) Want to change your theme? First, download some. Then create a "Themes" folder in the "_system_" directory. Put the themes you've download into this folder, labeling them "theme01, "theme02," and so on. You can have up to twelve. Then in your R4's main menu, press the select button to shuffle through your skins.
