Huh, I have Tales of Phantasia Nikarishi Dungeon rom itself.. maybe I can dig into the files and change the story a bit. I have the plot and title, Tales of 21XX, the X8 crew, and takes place after Jakob and Command Mission. Two world maps: one on the settlement (moon), the other on terra. A problem is that I should work effects that will do for them.
First things first, I need to make tilesprites for the overworld, and find a reason for Sigma to come back (as this one's really a fake). I should make a mav playable in his own mode, reminiscant of the Vile Mode in MHX, which gives him his own Final Boss.. and give a good reason why he is revived..
This may look like a good idea, but I don't know how to rip the coding from the game, and then paste it into either Game Maker or ClickTeam's simpler variant, MultiMedia Fusion. Ah well, at least I have RPG maker.
