Description

Issue Description

Hey @JackyJia73 , I got an MMD KMPRO16 keyboard but I want to set up a more complex tap-dance sequence than VIA allows, so want to use it with Vial, which needs me to port it.

I was sent the source code from the engineers and bundled in it was a readme with you as keyboard maintainer. Any way you could help? I tried to compile with source code given but it wouldn't work, and asking around on QMK/Vial discords other users have said the code is made for an older QMK version.

Research direction
First, identify the exact QMK version the provided source code targets and the differences with the current QMK version. Then, upgrade the keyboard's firmware to compile with the latest QMK, following the migration guide. Finally, integrate Vial support by adding the necessary keycodes and rules, referencing similar keyboards in the QMK repository. Compile errors should be debugged incrementally to ensure functionality.
