A few weeks ago, I had the urge to play FFIV again for the first time since my childhood. I wanted to play the original game before I tried out any of the great hacks available on this website. I agonized over whether to play the 2D Complete Collection on the PSP or the 3D remake on PC, followed by the 3D remake of After Years (all of which I had acquired over the years). The 2D version had the right feel for the game, but I liked a lot of the additions that the 3D version made. But the 2D version had the Interlude chapter. But the 3D version had extra story scenes. But the 2D version let you add Yang, Cid, Palom, and Porom back into your party at the end. But the 3D version let you just add their abilities onto other characters with augments. And so on and so on.
Finally, I just decided to play until Cecil became a Paladin in both version, and then keep playing whichever one felt more natural. I landed on the PSP Complete Collection. To make the Complete Collection feel like the definitive version, I wanted to figure out how to expand Cecil's spell list to the 3D list, adding in Protect, Shell, and Raise to make him a much more versatile magic user in the end game. I thought it would be a quick project. I was wrong. Nobody had mapped any code in the PSP version. I knew the code was based off of the GBA version, so I dug out a rom of that and stared working backwards. I will be uploading my notes to the documents section so that everyone has access to it. Anyway, because I started with the GBA version, there was no reason to not make the same changes there too. So I am offering this mod for both the GBA and PSP versions. For the PSP version, the mod is for both the original game and the Interlude chapter.
This mod adds the additional white magic spells from the 3D version of the game back into the 2D version. It's not a 1:1 match though. The games have a different leveling progression system, so I have placed the spells at levels where they would make sense in the 2D version. The final magic lists are as follows (new spells marked with an asterix):
-=Cecil's White Magic=-
Interlude: Cecil starts with all 9 spells.
-=Rydia's White Magic=-

One other thing:
In digging through the PSP code, I found something surprising. The additional Ninjutsu spells from The After Years are all present and functional, aside from "Frost" (which is basically the White Fang item anyway). They are not finished though. In the 3D versions, Edge has 3 of the additional Ninjutsu spells, Gale, Tremor, and Frost. If anyone is interested in trying to get this dummied content working, I'm happy to share notes with you.
