Claymore
3x3 Eyes
You honestly can't go wrong if you follow that guide step-by-step Claymore. I recommend the FF9 battle interface btw, the FFX one really doesn't suit the style of the game very much. And if you're trying to update but stay as true to the original as possible, go with the updated chibi models rather than the full characters in the field, sometimes the backgrounds look really odd with the full characters (the chair in Aerith's house is taller than Cloud for example).
Also worth noting is that a new installer is apparently being worked on because that one is a mess. It won't break your game or anything but just to let you guys know.
Thanks for the pointers. Gonna attempt it this weekend.
