I finally got a my first broadband connection of my own a couple months ago. So imagine my delight when I came across this guide that helps you connect your Dreamcast online via a broadband connection — without having to buy and expensive Broadband adapter.
While it is not as fast as a pure broadband connection, it’s a great cheap substitute and better than a traditional dial-up connection.
The process involves routing the Dreamcast though your PC via the modem.
Team this up with some of the Dreamcast gaming servers that are still online, and you have a retro-style online experience!
