Before I go on, does anybody have some sort of Gameshark/Codebreaker code for this game that gives you a full database or at least all the monsters? I'm too lazy to go around figuring the storyline and getting mons, or going through the whole 'build and break houses' thing at the start.
The below list includes my own crappy romanisations, forgive that.

Aquarius (アクアリウス):





Ancha (アンカ), Albali (アルバリ), Ruchbah (ルクパー), Sadalmelik (サダルメリク), Skat (スカト).
Pegasus (ペガスス):





Baham (バハム), Enif (エニフ), Markab (マルカブ), Matar (マタル), Scheat (シェアト).
