Like the first two entries in the Shin Megami Tensei series, the spin-off with the mysterious title If... got its own remake. As in the other two cases, the graphics of the remade version have been redone from scratch, to match the 2D standard of 32-bit generation consoles. Interior locations are much more detailed, with visible furniture and other items in rooms that were empty or contains just a few objects in the original version.
The 3D dungeons can now be navigated with smooth scrolling, unlike the "jumping" navigation of the earlier versions. The remake also has an additional difficulty level, dubbed "normal"; the original difficulty level is called "hard". The easier difficulty level also reduces the amount of random battles. Story, dialogues, layout of locations, and general gameplay remain unchanged in this version.
There is a special Playstation release of the game entitled "50th Anniversary Pack". It is dedicated to the 50th anniversary of Karukosaka High School, the one the events of the game take place. The game comes in a large box that contains the following: the game itself (no changes were made to the game), a Karukosaka High School pen, and a Karukosaka High School 2003 year calendar.
