Not port begging, but wouldn't it make sense to put this on 3DS? Considering that's where the latest entry in the series was released? (And was apparently pretty successful on.) You'd think it would be easier to sell the game on a platform that already has an established fanbase for the series.
I'm gonna point you towards
this video by RasenReviews that he just uploaded talking about this. He's a fan of the SMT series as a whole, but even he points out a lot of issues as to why a port to 3DS is not possible.
To give you an idea of what he said in the video: ATLUS USA is a publisher, not a developer, so that would mean that ATLUS Japan would have to do a completely develop a new port of the game for the 3DS or even just putting this version on the Eshop would require decent amount of work. And looking at what ATLUS has now coming up, they have Devil Survivor 2: Break Record, Persona Q: Shadows of Labyrinth, Persona 4 Ultimax: Ultra Suplex Hold, Persona 4: Dancing All Night, and Persona 5. Yes some of these are not being completely being developed by ATLUS completely, like P4D and P4U But even that is still a lot of game in development, especially for ATLUS, who is a small company, and would have to spend time and effort on resources that could go towards their other projects. And considering that this is a very old game, with outdated mechanics, even more so than Persona 1 and 2 or the PS1 Devil Summoner games.
And even then this would cost a decent amount of money to develop a new version of the iOS port or even doing a remake for the 3DS, since they would need do more than a cut and paste port of it, and would require a decent amount of time spent on programming of the game on the new system to make it work competently on another platform since it's a completely different animal compared to the iOS, this game is too much of a risk to make it available on other platforms, unless ATLUS JP decides to make a remake, were gonna have to live with what we have right here now in front of us.
