Hello, well using Windows CE to power the dreamcast, homebrew devs were quick to utilize this.
I know personally, I think I enjoyed the NES and SNES emulators that came out for dreamcast, being able to play 2 player games easily with a real controller.
The webbrowser with email support was nice as well allthough that wasnt homebrew.
What apps or programs do you know of that worked well on the Dreamcast? Maybe if its something really good, we all might try it. =)
