Mistel Barocco MD600 RGB Split Keyboard

keyboard firmware

What I remap

CapsLock is RCTRL    ... i do this on all keyboards
FN CapsLock is RCTRL ... was accidently toggling capslock with fn+capslock
LCTRL is FN          ... arrow/pg/home on right half, FN+arrow I now prefer on ALL keyboards... so nice
ESC is ` ~           ... no dedicated ` and ECS keys on a 60% keyboard like this
FN+ESC is ESC        ... can't say I use this much now that I map ESC to LSPACE

# really liked LSPACE as backspace but need ESC frequently, and while chording, so FN+ESC wasn't practical
#LSPACE is Backspace ... experiment, can't pay left thumb to do a space anyway. FN also an option
LSPACE is ECS        ... need ESC while chording, so FN+ESC was a no-go

Is it possible to flash TMK or QMK firmware to mistel MD600? Love this keyboard but better with spaceFN. Have to use a USB-USB converter instead.
Second that. Love the feel of this kbd
In terms of physical ergonomics, I get around the tenting deficiency (the fact that it's missing a peg base on the inside corners) by sticking bits of styrofoam there... ugly but... workable...
Worked with support to try and configure to an efficient mapping. Works but one mistyped chord throws it into "programming mode" while I'm typing and before I know it I have "reprogrammed" something and I don't know what... So it's back to the drawing board, reset that layer and reprogram it, colors and all...

That's happened one too many times and now it just collects dust...

I need to recode the firmware.
Anyone know what it is?
Any way to reverse engineer and fix it?

Or flash something else into it?
