Thanks for the info! At least now I know Tiny usb should work and I’m doing something wrong

give me a little more information about your project, what exactly it should do, how the rp2040 cores are used, what USB are you using, hardware or software?

I've got a box of computer parts. I'm sure I have a bag of buzzers in there somewhere.

PC buzzer has a built-in frequency generator, it is not suitable
i can add a buzzer output with a frequency generator, but in this case it will always sound the same without the ability to change the tone of the sound with dreamcast

P.S. you can find passive buzzer in PCI Dial Up modem

Added buzzer support.
passive buzzer connect to GND and GP6
active buzzer connect to GND and GP7

active buzzer can't chenge tone signal, better use passive buzzer

GP7 made a "clicking" sound when I saved.
GP6 made a loud tone when I saved.

Therefore, I think my buzzer is passive.

yep, your buzzer 100% passive

Hi, can you tell me which game are you using to test if buzzer is working? I have tried a bunch, but none of them makes sound (or there is issue with my wiring, although everything else is working).

And the other board with green leds on your setup, is it acting as usb hub? Can you tell which one is it?

Thanks

Whenever you save, the VMU buzzes. So in GDEMU, I am just clicking save on the settings screen.
