Atomiswave

The Atomiswave is a custom arcade system board and cabinet from Sammy Corporation.

It is based on Sega's Dreamcast console, sharing similarities with the NAOMI, as far as it uses interchangeable game cartridges, as well as a removable module for changing the control scheme (including dual joysticks, dual light guns and a steering wheel), but unlike the NAOMI, the Atomiswave does not feature expanded RAM compared to the Dreamcast.

[3][4] In a contract with Sammy, SNK Playmore agreed to develop five games for the Atomiswave system.

[5] In Japan, the Atomiswave was able to connect via a special modem to the AW-Net online system set up by Sammy.

AW-Net was discontinued on 30 November 2006 following the merger of Sammy and Sega; the follow-up system was ALL.Net.
