Use the git-keymap.c in this repo and put in the usual QMK keyboard folder. Do the usual compile and flash the .hex file as per the QMK instruction at https://doc.qmk.fm.
The mapping for the keymap is this:
QMK Bootloader: While plugging in the USB-C cable, hold the top left key, commonly programmed as Esc to put your board into bootloader mode.
Flash file: space65.json
QMK Bootloader: Quit QMK. Plugin, then hold both shifts + B. Then, open QMK.
QMK Bootloader: Hold ` while plugin in (second key).
QMK Bootloader: Put your Tokyo60 into boot loader mode using L_SHIFT+R_SHIFT+B.
The default layout uses FN+p for PAUSE.
I use left 2u Shift (ughh) with directional keys.
JSON configurator file: dz60_direction.json
QMK Bootloader: Spacebar + B
