ShipEdit was done for SFC 1, 2 and OP. Core Edit if you search the General forum you will find a beta of it was made for SFC 3.
The last Version of ShipEdit was a Beta I wish it was completed by things happened at the time that made it impossible, but either way i am still glad it was made. Even the Beta was a good deal better that The first OP one, I just wish it would have been completed, but even if it had the Patches would have forced it to need updating as well.
