FFVI: Veteran Edition

Finally, an event-related question! I haven't seen one in ages now.

I'd like to make it so the Weaponsmith in Narshe in the WOR gives you the Ragnarok sword automatically

For the first case, it's a very simple event edit. You simply have to remove the option of the player to choose between the esper and the sword by replacing the following code with the command "FD".

Code:

CC/0B37: 4B    Display dialogue message $05EF, wait for button press
               I ran a Weapon Shop for 70 years!
               This stone gives off an eerie aura!
               If I melted it, and forged a sword, it'd be powerful!
               Well?
               Make this stone into a sword?
               ^ Leave it the stone “Ragnarok”
               ^ Make it the sword “Ragnarok”
CC/0B3A: B6    Indexed branch based on prior dialogue selection [$CC0B42, $CC0B58]

Then, before the FE (which ends the event), you'll want to do a jump to the event code that grants the sword to the player. Before the FE, you'll want to write the following bytes:

Code:

B2 58 0B 02

This should make the old man give you the sword no matter what, it would be a matter of polishing the text to create whatever situation you want.

And Pug, the enemy in Narshe Mines gives you the Esper. But I'd like to make it an event that occurs after the battle with him.

Now, for the pug battle it's a little bit more complicated. You would have to place an NPC sprite somewhere in the cave (using LE) and have the NPC trigger the battle upon talking to him. After the battle is done, you want to check whether the party won or lost the battle. If the party won, the event continues as normal and the esper is granted to the party. If the party loses, it's game over screen.

To do this, you need to know how to use the If/Else command, as well as manipulate an event bit or two in order for the event to happen once, and only once. I can help you through the process, just let me know what other questions you have.
