Demon Fusion Search Tool
List of Fusion conditions
I compiled information about the Fusion conditions in Shin Megami Tensei IV. Demons with Fusion conditions cannot be created by fusion until specific quests are cleared or bosses are defeated.
The majority of demons with Fusion conditions are created by special fusion. Please check the for recipes.

How to Play SMT IV Now?
Unfortunately, preparing the play environment can be challenging.
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.
Is it impossible to port to newer hardware after this?
You guys probably don't want to bother with the kind of maintenance required for a port, right?
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.
