Atomiswave

Template:Short description Template:Refimprove Template:Infobox information appliance 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.

With the retirement of the aging Neo Geo MVS system, SNK Playmore chose the Atomiswave as its next system to develop games for. In a contract with Sammy, SNK Playmore agreed to develop five games for the Atomiswave system. Metal Slug 6 was SNK Playmore's fifth game for the Atomiswave, after which SNK moved on to a Taito Type X2 arcade board. Sega ended technical support for the system and its games on March 31, 2017. Since its discontinuation, the Atomiswave library has received homebrew conversions to the Dreamcast.

AW-net

In Japan, the Atomiswave was able to connect via a special modem to the AW-Net online system set up by Sammy. The AW-Net was primarily used to play online with other players and to create online player rankings. AW-Net was discontinued on 30 November 2006 following the merger of Sammy and Sega; the follow-up system was ALL.Net.
