Hi there. I'm the creator of FFT: Emergence, one of the only complete hacks for the PSP version. I would prioritize the following:
1. Fix whatever bug in FFTactext is making the new versions incompatible with WotL. Users are stuck using version 0.457, and saving is not possible.
2. Make a small tool for the PSP that allows people to change the requirements for Onion Knight, Master Onion Knight, and Dark Knight.
3. Make a tool that can truly switch skillsets around. Right now, I can switch the Archer and Monk skillsets, but JP gained from one job goes to the other, and vice versa.
a distant 4th: Work on PSP ASM.
