Homebrew and community ports

Independent development and unofficial ports for Atomiswave, including Dreamcast games adapted to run on the arcade hardware.

Dreamcast games on Atomiswave

Arcade-Projects member Chrone has been porting Dreamcast games to Atomiswave. These are community conversions, separate from the original commercial game library.

Ikaruga

Port complete and playable; public release unconfirmed.

In the 11 July 2026 announcement, Chrone reports Ikaruga running on Atomiswave using Sports Shooting USA as the base ROM, arranged to work with aje_fr's multicart. A release was promised in the thread; public availability remained unconfirmed when it was checked on 14 October 2026.

The 12 July follow-up says the options menu remains accessible, but settings do not persist: the Dreamcast flash shim lives in ordinary RAM.

Mars Matrix and Power Stone

Chrone also reports work on Mars Matrix and Power Stone in the same thread. The July follow-up describes a standalone Mars Matrix cartridge as a next step after running it on the multicart. It does not establish a public release date for either port.
