Have you been using a different psu lately other than the official one from Raspberry?

Add this to cdmline.txt :
usbpowerdelay=100

cmdline.txt should be an all one single line using Spaces as separators.
Also cmdline.txt doesn't like empty lines.
Hi adonet,

Default value for usbpowerdelay is 510, so you can need a value around 1000.

[mention]hikoki[/mention] [mention]zx81[/mention] Changing to another PSU doesn't change anything.

Adding this to cdmline.txt :
usbpowerdelay=100

separated with a space on the same line doesn't change anything as well.

I keep getting the message that I "have to change the keyboard membr".

I tried without batterys in the Recreated ZX Spectrum since they could use current for charching. No change
I tried starting with the keyboard switched off. No change
I tried starting in Mode B. No change

I used another SD card with Retropie and FUSE 1.3 or ZEsarUX81 and then the Recreated ZX Spectrum works fine. Switched on or off seems only to affect Bluetooth pairing possibilities. Connecting via USB to Retropie seems not affected by the power switch of the Recreated ZX Spectrum.

Does anyone have another suggestion? Thanks.

Thanks a lot. I'll keep testing further now.

I have got another question. Is there a parameter I can use to tell the zx baremulator to use another aspectratio. On my 10 inch 4:3 monitor the image is to much a square instead of a 4:3 TV screen. While my normal 16:9 monitor gives a good image.

Thanks

Jeroen

The image format is controlled by PI firmware and the TV set, not by ZXB. You can try to play with parameters on config.txt file.

hdmi_group=1
hdmi_mode=2

did the trick, after I made the monitor zoom in a bit. Thanks for the tip.

I found some tips on

That's 60 Hz. Try hdmi_mode=17 to get 50 Hz

^^^ you are welcome. You may want to try this
# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
#disable_overscan=1

Disabling the overscan seemed to work only horizontally, but changing a zoom setting made the picture very good.

Thank you very much for your help.

It looks like this now:
