Customized RetroArch for clockworkpi

Introduction

This customized version of RetroArch enables new features for using specifically with the clockworkpi GameShell.

The new features are:

• Wifi management.
• Bluetooth management.
• On-screen Keyboard working with the GameShell keypad.
• New on-screen hardware monitoring: Temperature, and cpu frequency.
• Brightness adjustment on main menu.
• Shutdown, and restart on main menu.
• Battery monitoring Now it works with vanilla RetroArch :)

Configuration

After running for the first time, two new options will be available in the retroarch.cfg config file:

temp_show = "true"
cpufreq_show = "true"

These options append the temperature, and fequency monitoring to the fps counter (fps_show option) when it is enabled. In the future I'll add it as an menu option.

The wifi menu is under settings > wifi

Troubleshooting

• Wifi doesn't scan
  • Wifi menu seems to work only with menu widget enabled, so enable it in settings > On-screen Display > On-Screen Notifications > Graphics Widgets.
  • Try to go back in the menu, and return to the wifi menu.
