I'm fairly new to modding, but I have been getting the hang of it bit by bit by myself. Though I still have quite a bit to learn and programs to collect before I make a worthwhile mod. I am a big Anime-type of guy, and am the author/artist to a manga called Praigaku.
Ok, as far as I can, I have edited heroes who have ships, to have the era ships that I want.
Thrawn - Imperator-class Star Destroyer (Chimera) - Dragon Destroyer
Piett - Imperator-class Star Destroyer (Admonitor) - Dragon Destroyer
IG-88 - IG-2000 - Sith Destroyer
Tyber Zann - Krayt Destroyer (Merciless) - Harrower-class Dreadnought
Changes have been made to the following -
Kedalbe-class Battlecruiser - was Strident-class Star Destroyer - Is now Galaxy-class Fleet Carrier
Krayt-class Destroyer - Centurion-class Battlecruiser
New Hero Unit - Chiren Guinn (Guinn Dynasty leader) Personal ship - Executor-class Super Star Destroyer (Because I do not have the Nemesis-class Super Star Destroyer)
