Of course, the legal and ethical shadow of ROMs is impossible to ignore. Distributing Atomiswave ROMs is technically a violation of copyright law, as Sega and the games' developers hold the rights to these titles. However, the debate is nuanced. Most Atomiswave games are long out of print. The arcade cabinets are scarce, and Sega has shown little interest in re-releasing this library.

It meant that games like King of Fighters XI and Metal Slug 6 , which were never officially ported to the Dreamcast, could now be enjoyed on the very hardware that powered them.

The Atomiswave never gained the install base it deserved, and many of its games remained trapped in Japanese arcades, inaccessible to the wider world. Of course, the legal and ethical shadow of
