Game Boy Speedrun Emulator 0.5 9/01/2026

This release is mainly a bug-fix and internal improvement release. The biggest change here is the move from SDL2 to SDL3. SDL is a library that handles a lot of things internally in GSE, most notably it handles controller support. SDL3 offers even better controller support than SDL2, such as Switch 2 controller support.

For now, this is mostly a straight port, which offers better support for things currently used in SDL. Over time, more features may be able to be introduced due to this move.

A minor feature introduced in this release is a "Low Latency Mode." This is a mode that offers even lower latency, at the potential cost of slightly less consistent frame pacing. It is disabled by default, as it's assumed a runner will generally prefer more consistent frame pacing over lower latency. Besides this mode, other changes have been made to improve latency across the board.

Memory exports have also been fixed for macOS and Linux. These are used by autosplitters, which are currently Windows only. This allows macOS and Linux support to be possible for autosplitters, if such end up being developed.

NOTE: The default audio latency has been raised to 35 ms, as various users have reported issues with the previous default of 0 ms. This change won't affect existing configs (only new configs), so users updating are recommended to change their audio latency to the new default.
