GUI Priority

Priority Panel

The Priority panel controls the CPU scheduling priority of the emulator process and what happens to emulation, sound, and input when the emulator window is active, inactive, or minimized.

When Active

Settings that apply while the emulator window is focused and the mouse is captured.

Mouse uncaptured: Pause emulation

• Pauses emulation when the mouse is released from the emulator window (e.g. after pressing Alt+Tab or the untrap key)

Mouse uncaptured: Disable sound
