Just a thought, MonkZy. Try another cable on your gamepad. I've read these disconnecting problems happen sometimes with Sony Ps3 gamepads. One solution could be as simple as using another cable

Looking forward to the update. Even with the bug the emulator is usable, have been playing on it a few hours this evening.

[mention]hikoki[/mention] I think the usb port on my controller is quite worn out. With some care I have had a few hours of gameplay, having something that causes trouble if you wiggle it makes for an authentic speccy experience I am sure a blob of blue tac will help.

Would a PS3 compatible controller work? I have seen non-sony wired controllers on eBay for reasonable prices.

Monkzy, glue?? you may want to try putting a small piece of paper either on the top, bottom or side of the loose usb socket

PS3 controllers drivers can be Official, Gasia or Shanwan.
I can say that my clone using Shanwan driver does not work with this emulator.
Would Gasia ones work? Will there be cheap clones using Official? I don't know

I'm sorry by the delay. Many PS3 compatible gamepads are PC and XBOX compatibles also, and do many strange things when are initialized. A few months ago I buyed a Trust GXT-24 and, finally, I should returned it because I can't use (and is bad quality, really).

I've updated the ZXBaremulator beta v3.H.5 on DropBox. The problem solved only affects to Raspberry PI-3 models.

This version is tested on a new PI-3-B+ too and works flawlessly.

Can you provide a link for the 3.H.5 version. The link at the top of this thread is for the 3.H.3 version.

Thank you. The new icon to indicate extended keyboard mode is a good improvement. I will give it some testing. I have fixed my controller by building up some blue tac around the usb plug

Hi fellow ZX Spectrum users,

I downloaded version v5.H(ikoki) beta and first it worked OK, but now after several days the Recreated ZX Spectrum keyboard doesn't work anymore in the ZXBaremulator.
When I connect it together with a normal USB keyboard, I can only use that keyboard. The Recreated ZX Spectrum keyboard keys don't work. Both is mode A and B of the keyboard.
When I connect only the Recreated ZX Spectrum keyboard and boot the ZX Baremulator, it gives after booting a massage stating that I need to
"replace the keyboard membr". And no key is working at all.

I know that there is nothing wrong with the Recreated ZX Spectrum keyboard, since it works fine in other emulators running on the very same Raspberry PI, connected with the same USB cable.

Doe anyone have any Idea what to do?

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.

I tried now with usbpowerdelay=1000 and that works

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

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
https://www.raspberrypi.org/documentati ... t/video.md

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

That works even better. Thank you hikoki.

^^^ 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:
