Firstly, thank you very much for creating ZXBaremulator, a great accomplishment :)

I can understand if you're not really motivated to support sound on the Pi-Zero. But I do like to shine some light on the BMC64 implementation, as there are some incorrect ideas.
BMC64 includes a so-called BMC64-Lite version which is being booted if a Pi-Zero is detected. I tested it yesterday and I have sound from my monitor's output jack - no need to do something with GPIO. More info on what concessions are made in the lite version, you can find here: https://accentual.com/bmc64-lite/

Hi, great emulator. I use Raspberry Pi models B +, I connected a 5x8 physical keyboard, there is a problem. If you press C.S. and hold, then the buttons A, Q, 1,0, P all the others that are in the same line stop working. If you hold the S.S. button then K, O, 9.2 and the rest who are on the same line do not work.
Is it just me on my PI B + model ???

Is your keyboard a standard Spectrum keyboard?. The ZXB code don't prevents such key combinations.

I have a clone of the standard keyboard made on reed, contact buttons, a 5x8 matrix, as in MagPI67, I think that the emulator cannot process two buttons simultaneously.

If I press only one button, on the KB1-1 and KB1-2 lines, then all the buttons work.

I've tested the emulator using an Amstrad 128k (grey case) and all works correctly, testing it with this program:

I can't find any limitation reading keys.

Thank you for your time, I will try this test, I will write the result later.
I noticed one more feature of my raspbery, it does not load TAP files, stop screen and work.
I started a topic about ZXB on my forum, I ask that other users check, then I will report the results.
The emulator would be complete, you need:
1. hardware reset, via GPIO
2. Input reading tape through GPIO
3. The ability to substitute your ROM and select which ROM to load at startup.

I’m an old fool, I didn’t notice the diodes in the photos, looked from a smartphone, put together a new keyboard, everything worked as it should, note in the instructions on the ZXB page for idiots like me.
