International visual novel localizer / publisher JAST USA have recently announced that they are abandoning the Software Defender DRM that they included a number of their recent and not-so-recent titles including Aselia the Eternal, Deus Machina Demonbane, Princess Waltz and Yume Miru Kusuri.

Transition from a DRM to non-DRM copy will not be automated, but will instead require you to download a new launch executable file through their official website. Alternatively if you still have a download activation left, all new download files will be without the DRM content.

A full list of titles affected by this update is available below:
