The PCSX2 development team today released version v2.9.84 of the PlayStation 2 emulator. This update primarily introduces a new Controller Tester button to the emulator's Qt-based user interface. This feature is designed to assist users in verifying and configuring their game controllers directly within the application, aiming to streamline the setup process for gameplay. This follows the v2.9.80 release just yesterday, which added a -gamecfg command-line argument.
