ChoralRoot 0.24-beta3-smk37: a community test build for the M-Vave SMK-37 Pro, SMK-37 Elite and MKE-P37 (and the Starrykey 37 Play, which takes the Pro's package). Community-tested, not tested by the maintainer; genkigenki's port (https://github.com/genkigenki/fm1-to-smk37). Read SMK37.md first.
One package per model: choralroot-0.24-beta3-smk37.fwsc (SMK-37 Pro, Starrykey 37 Play), -elite, -mke; each has a -1core twin for a keyboard that crashes or freezes with the standard one. Install with the SMK-37 test installer (the link testers were given) or python3 tools/fm1_install.py FILE. The way back: M-VAVE's package for your model with M-UPGRADE.
SHA256SUMS lists every package and app. The packages hold three JieLi AC79 SDK files (Apache-2.0); LICENSE, LICENSING.md and LICENSES.zip carry every licence. Installing firmware is at your own risk.
