you have to find the unit's sound set you want to replace in the sound editor, and then manually replace each individual sound in the set. (right click on the sound and select "replace internal sound")
Guys just a heads up I am going to be shutting the site down soon. I am just waiting on the NUON people to decide whether they want to transfer forum data and keep the discord. My email is [email protected] for anyone that wants to keep in touch and I have a facebook too. I will make an official post later. Love you guys and will miss everyone!
I'd rather personally just own a backup of the Nuon data than see it go to AtariAge honestly. If it gets enshittified as per usual, or if some of the "regular" Jaguar folks get there, it's not gonna be fun
