I had a program that came with special CD Labels for the printer where you could make your own cool CD label covers. that was fun.
Or going into a Dreamcast IRC channel to download games and burn them to disk. I think I only ever actually bought like 2 Dreamcast games, Shenmue and Seaman, the rest were just burned to CD-Rs.





For the DC? yeah, it would play burned CDs no problem.
For the playstation? not sure. I had mine modded so I could import games from Japan but I don’t believe it could play burned CDs.
Xbox and the 360 were easy to mod though and you could play burned games on those also.
But yeah the Dreamcast just did it right out of the box. no mods required.
