Best Miryoku firmware for a hand-wired, split, wired skeletyl

I built this lovely bastardkb skeletyl and initially used a bit with miryoku kmk. I noticed for whatever reason that sometimes the right side hung up and now after flashing the latest kmk it does not seem to work at all.

It is well soldered and I somehow believe it's really a kmk issue - followes all the rules for Split etc. I often also had little timing issues with the hold-tap behavior which is really non-existent on zmk and other boards for example.

Long story short: I am using waveshare's rp 2040 zero in here and would want to try out another firmware for miryoku. I will need to configure the board pins, it's hand-wired. What can you recommend to get it done with minimal effort?

QMK?

For a hand-wired 3x5+3 I'd suggest wiring according to the crkbd schematic as crkbd is already supported in QMK, ZMK, and KMK. Then you won't have to make a custom keyboard definition, and can rule out firmware issues. You can download the PCB files from the crkbd repo and view the schematic in kicad.

I'd suggest using QMK rather than KMK due to https://github.com/manna-harbour/miryoku_kmk#issues.

For ZMK on a split, if your MCU doesn't have BT or if the BT is not supported by ZMK you'll need to use a different MCU as ZMK doesn't support wired split comms.
