GroovyMame v0.289 Switchres 2.22f is released. GroovyMame is a custom M.A.M.E. build mainly aimed at CRT monitors, as we are convinced CRT technology is a must when it comes to enjoying emulation in its full glory. However you can use GroovyMAME to alliviate some of the annoyances associated to emulation on LCD displays, specially for those models which are capable of refreshing at custom rates.

GroovyMame Changelog: Audio latency reduction and code fixes/simplifications
* For games not using VIDEO_UPDATE_AFTER_VBLANK, shave off vblank time for audio latency
* Register minimum count buffer count across both audio updates for emusynclog
* Update audio at m_vactive_ratio instead of 1.0, pushes audio earlier and reduces end-to-end latency, but maintains non-negative latency without -afd
* Reduce minimum buffering latency to 0.1 ms, increase skip duration to 1 second, decrease minimum adjustment to 0.25 ms, only really matters for PipeWire
* Fix XAudio2/WASAPI available() calculation
* Add mutex for sink registration
* Fix out-of-bound read resulting from fractional audio updates, fixes gyruss (and maybe others)
