I've figured it out!! Now, the rom hack I originally had planned is already complete, so at this point it is sheer script base editing...
Keep in mind my rom hack DOES NOT support the marriage of Maia... IF people really enjoy this hack, and it is successful, I WILL make a copy specifically for marrying Maia, and Ayn's quest.
To explain why, I feel that the endings of Nial's children are more entwined with the ACTUAL Phantasy Star Time line we had all researched and made before... This hack SPECIFICALLY is for Aron, however, Adan shouldn't cause trouble in the selection as far as shops and equipment is involved...
SO NOW, based on that, feel free to hit me with ideas, story, and theories of Phantasy Star III and I will use your suggestions, and we will have an UNDERSTANDABLE copy of Phantasy Star III
