PCSX2 v2.9.158 pre-release updates SDL3 dependency

The PCSX2 development team has released version 2.9.158, a pre-release build of the PlayStation 2 emulator. This update focuses on maintaining the project's underlying dependencies to ensure compatibility and stability within the emulator's environment.

This specific release primarily involves an update to the Simple DirectMedia Layer (SDL3) library. By moving to SDL3 version 3.4.20, the emulator benefits from the latest improvements and bug fixes provided by the SDL project for handling input, audio, and windowing tasks.

Why it matters

Regular dependency updates like this ensure that the PCSX2 emulator remains compatible with modern Linux desktop environments and gaming hardware. For users of Steam Deck or other Linux-based handhelds, keeping the SDL3 backend current is vital for stable controller input and display management.
