Atlus Persona/Shin Megami Tensei Feature Phone Games

well what does exist for now? i mean it should be some images to prove thier existance

All of these except for the Chinese version of Digital Devil Story: Megami Tensei, or, as you called it, Digital Devil Monogatari Megami Tensei are lost. It has actually received an English fan-translation, too, so I'll attach the .ips file, appropriate original .jar file, and a patched version of the game.

I know that it isn't much, but it's most of what I can offer -- I'll attach some other random bits in relation to these games at the end of this reply.

Thank you for bringing these back to my attention; I really do hope that the rest of these are preserved! I'm aware that one user on Twitter bought a phone with one of these games on it, promised to upload it, and then seemingly fell short. If I can find their page again, I'll contact them.

Okay! @bardeenocasino, the Twitter user who had the phone, says, "Hello! I gave it to Larrue @didyaknowtensei for his birthday, its up to him with what he does with the phone and its contents." I'll contact Larrue and see what he says -- he's usually kinda slow to reply, but I've never turned up empty after getting into contact with him. I really hope that we can get this dumped soon!

With P3 Reload happening maybe they’ll rerelease Aigis TFM….I doubt it but hey, we can hope. And at least footage of it exists.
