The '''Atomiswave''' is a custom [[arcade system board]] and [[arcade cabinet|cabinet]] from [[Sammy Corporation]]. It is based on [[Sega|Sega's]] [[Sega Dreamcast|Dreamcast]] console, sharing similarities with the [[Sega NAOMI|NAOMI]], 
as far as it uses interchangeable [[game cartridge]]s, as well as a removable module for changing the control scheme (including dual [[joystick]]s, dual [[light gun]]s 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 (console)|Neo Geo MVS]] system, [[SNK Playmore]] chose the Atomiswave as its next system to develop games for.<ref>{{cite news |title=Final NeoGeo game to be released in July |url=https://www.gamespot.com/articles/final-neogeo-game-to-be-released-in-july/1100-6093896/ |access-date=13 May 2022 |work=GameSpot}}</ref><ref>{{cite news |title=SNK to Atomiswave |url=https://www.ign.com/articles/2004/02/20/snk-to-atomiswave |access-date=13 May 2022 |work=IGN |date=20 February 2004 |language=en}}</ref> In a contract with [[Sammy Corporation|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 X]]2 arcade board. Sega ended technical support for the system and its games on March 31, 2017.<ref name="atend">{{cite web|url=https://www2.sls-net.co.jp/cms/sls/pdf/news/201611_p_maintenance.pdf#page=14|title=弊社製品保守対応の終了について|publisher=Sega Logistics Service|date=2016-11-30|accessdate=2024-04-25}}</ref><ref name="atend2">{{cite web|url=https://www2.sls-net.co.jp/cms/sls/pdf/news/16_12_SEGA_Parts.pdf#page=11|title=Announcement on sales termination of the maintenance parts for SEGA products|publisher=Sega Logistics Service|date=2016-12-16|accessdate=2024-04-25}}</ref> Since its discontinuation, the Atomiswave library has received homebrew conversions to the Dreamcast.<ref name="RetroRGB"/>

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]].
