PiMusicbox PiZero2w support?

Can anyone help me to get PiMusicBox running on a Pizero 2w please ?
I get the rainbow screen when trying to boot from SD card using image V0.7.0RC7

I’m particularly interested by this question as I’m in the same case.
Also the led doesn’t blink at all. I changed the configuration file with my wifi network name & password, but it doesn’t connect.
