DeSmuME SVN Changelog:
r4179
Cocoa Port:
- When detecting an analog input's on state, use the upper/lower third of the range instead of the upper/lower quarter of the range. This helps improve compatibility with certain joysticks.
- Perform an integer length bounds check before calling IOHIDValueGetIntegerValue(), since this function will cause a crash if the returned integer value is very large. This prevents crashing when using certain controllers, such as the PS3 controller.
- When mapping inputs in Input Preferences, require the user to hold the input in its on state for at least 0.1 seconds. In addition, the user must also perform a full on-off state transition with the input. This helps stabilize jittery inputs, and also helps ignore unintentional inputs from devices that constantly throw a large number of signals, such as the PS3 controller's accelerometer.
- When mapping inputs in Input Preferences, remove all previous mappings for the particular control before mapping the input. Since the UI doesn't yet support
