RetroArch is a modular, multi-platform, multi-system emulator.
Major changes in 0.9.8 -> 0.9.9:
- Replaced Zenity launcher script with PickleLauncher
- New default settings, including using GLES video driver by default
- "RGUI" in-game menu, brought up with spacebar by default
You may need to delete (or move to a backup location) /pandora/appdata/retroarch for the new defaults to take effect.
