GAME ZIP 64 - LED matrix not working. Is it broken?

I know there’s an issue with the GAME ZIP 64’s LEDs in MicroPython at the moment, but mine isn’t working with MakeCode either.

I created a test program to display a rainbow on the whole display, but only the first nine LEDs will light:

Even the pre-built Snake game from fails.

Interestingly though, if I use the beta version of MicroPython, I can use the whole display.

Anyone have any thoughts? Have I got a broken GAME ZIP?

I have the same problem, but only the first four LEDs work for me.
I can’t even get it to work on the beta version of MicroPython.
Strangely though, when I turn on the the GAME ZIP most of the LEDs shortly light up.

Have you found out why this is happening?

Mine wasn’t working too, but i managed to fix it by shaking it.
