Re: ZXBaremulator 3.2

The gamepads suported are specified on the project page.

Others gamepads could be detected using the HID descriptor, but isn't probable that the controls are correctly mapped, and you need a specific button to select the joystick model to emulate.

Hi, Go to https://github.com/raspberrypi/firmware/tree/master/boot and get all the *.dtb files, start.elf, fixup.dat and bootcode.bin, update these files on the SD and, probably, Z...

José Luís, Thank you for your like. Unfortunately, I am a little bit disappointed with my project because with a Raspberry zero w I don’t have sound via HDMI. Do you think it’s possible to have sound via a USB audio device like this !? Regards, Luís Godinho https://i.postimg.cc/tYjQt9gD/pi-usb-soun...

I have a few of them, of course, but you can generate it with JSpeccy. The emulator can read any MDR file and convert it to MDV.

In "Non-Spectrum specific hardware emulation" section you can add ZXBaremulator, http://zxmini.speccy.org

And in "Hardware systems - clones" you can add MiST/Mistica, SiDi and MiSTer, IMHO.

Re: ZXBaremulator 3.2

You can reset the emulation pressing CTRL+Pause. Some reduced keyboards don't have the Pause key, that's true. For the PI 3 version, I've added two key combinations, Alt+P to pause and Alt+R to reset. But I haven't compiled the these version for Pi-2/1. When you have a micro-SD with Linux, you can ...
