I've put together my own DreamPi kit using parts that should work according to the dreamcast live website (Raspberry pi 3, 32GB microsd card flashed with DreamPi 1.8 DLE, a Dell External 56k USB Modem adapter, and regular Ethernet/phone cables). My console is a V1 japanese import, and I replaced the included modem with a 670-14140A modem from a US console. I get both green lights on the USB modem adapter, but can't get any dial tone, so the only explanation has to be it's somehow not getting enough power, and I need a line-voltage adapter, right?

You dont. Do you have setup your Dreamcast with a browser like XDP or Dreamkey 3.0?

You need line voltage. Even if you have one of the DC modems that doesn't, the USB modem still does

If you're using a usb modem to raspberry pi you must use a line voltage inducer. You can get one premade here or he may even be able to upgrade the one you purchased provided its the correct one https://dreamcastlive.net/shop/

I was wrong, sorry. You need line voltage inducer.

While installing inside the modem is convenient for regular use; however, I find testing modem can be done with a separate line-voltage inducer.

Dragoncity17's design uses USB power without requiring a battery. The design involves beginner-level soldering with no risk of damaging a useful component. It's certainly worth checking out the tutorial and deciding if you are capbable of this DIY solution.
