Figured I should offer an update on this front too. Just got back to playing around with this game for the first time in quite a while.
Granted that I finish Elibian Nights early (which is obviously my full intention), I'm going to try to have a 4-chapter demo of this out for FEE3 as well. After that small demo comes out, I'll be shifting my focus to Project Fire Shell; once that's complete, I'll start by rebuilding FE1 with the basic Fire Shell ROM.
Going forward, I've got an excellent assistant in @Ash3wl, who will be doing the first drafts for the game's events. Now I just need mugshots.
