Risks

  1. External Library Dependencies: Issues like #16672 and #16668 show vulnerabilities due to dependencies on external libraries such as mbedtls and FFmpeg. These dependencies could lead to critical build failures as these libraries update, potentially impacting RetroArch's functionality on various platforms.
  2. Hardware Compatibility: Issues #16671 and #16669 indicate ongoing challenges with hardware compatibility, particularly with newer controllers and operating systems. This could affect user satisfaction and software reliability.
  3. Resource Management in PRs: PR #16602 discusses potential inefficiencies in resource management regarding shader parameters, suggesting that current implementations might not be optimal for memory usage.

Of Note

  1. Focus on Accessibility: Continuous emphasis on improving accessibility (noted in contributions from Thiago Seus and others) enhances the inclusivity of RetroArch, making it accessible to a wider audience.
  2. Platform-Specific Enhancements: The concentration on refining the experience on iOS/tvOS platforms as seen in multiple commits from Eric Warmenhoven indicates a strategic focus on these platforms, possibly due to their large user base or specific market strategies.
  3. Audio Driver Stability: Multiple contributions towards stabilizing the WASAPI audio driver (audio/drivers/wasapi.c) reflect an ongoing effort to ensure robust audio performance on Windows platforms.
