I know the re are a lot of people asking the same but I can’t figure out how to solve it!
So, I live in Italy but my dreamcast is JAPAN ( i swap the PSU with a Pal one )
I have a Rasp 3 with dreampi ( the last one)
And i use a V.TOP usb modem and the Lights are both green. Sono think everything work...
I see the IP and if i do the ping test I can see the dreampi
But when i try to connect the game ( quake 3 ) said no dial tone..
Any suggestion?
Thanks!!

I MODIFY MY dreamcast With MODE by Terraonion
Sometimes i have a warning “ under-voltage detected”
