Maturion ported Pocket Volleyball to the Dreamcast.
It is a very basic port. There’s no sound, no joypad-support and no AI. That means you need someone to play with and a keyboard. Pad support and some other goodies such as additional playable characters will be added in the next release.
Thanks to Maturion himself for the news via the PDRoms webboard. Download links are available via the release thread.
