This software was released on the Nintendo 3DS in 2013 and there have been no ports or remakes since. To make matters worse, in September 2020, the hardware was discontinued, and in March 2023, the official store stopped selling the download version.

The DS and 3DS are quite tricky platforms, especially since games are designed with a dual-screen layout.

Even as of 2023, it should still be possible to play it by purchasing used hardware and software. The 3DS is the exclusive platform for various Atlus titles like the Shin Megami Tensei IV series, Soul Hackers, Strange Journey, and Devil Survivor series, making it a worthwhile device for Atlus fans.

With the store discontinuation, I believe you can no longer buy DLC, but it doesn't affect the core game, so you can still have plenty of fun with used software alone.
