Can please someone show me step by step all the files needed to be replaced for s unit from firestorm to rotr for example

Tried adding the a10 n crashed the game added the object type by deleting the spot the comanche and put the a10 yet there then i added the weapons to the weapons section...what else was i supposed to add? Or did weong game crashedq

What do you mean by "deleting the spot the comanche and put the a10"? Do you mean you replaced the Comanche's button the the airfield's comandset, or did you literally delete the comanche object codes and add the A10's in it's place?

If it's the latter, you can't just delete units from the game, it will break stuff and cause the game to crash, you have to code it in as a new unit, and just replace the factory build button.

I guess the object code found the comanche in the rotr pb ini put the a10code in the hopping the a10nwould produce instead of the comanche also put the weapons code in, what should i have done to make this work correctly. The a10 was from firestorm

1. Extract the ini files you need (ex. Weapon.ini, Armor.ini, etc.) Save them in the correct directory in your ZH folder (or wherever you installed ROTR to).
2. Put the A10's codes in it's own ini file, save it in "Data\INI\Objects\America\Aircraft" folder (if it doesn't exist, create it).
3. Extract and open CommandButton.ini and CommandSet.ini, create a new button for the A10 in CommandButton.ini, and add it to the USA airfield command set in CommandSet.ini.

4. Save and play.
