@southpaw9999 did you try google?

 

This changes all battles tho, but you could just on and off the code.

If you only want to change one specific trainer, you’re gonna need a ROM edit (or maybe a really complicated code) and I’m not sure if anyone can help you.

Turn on the code whenever you battle Silver, then turn off the code when battling others.

I imagine most people don't do HGSS coding anymore. No need to reply to this.
If anyone can help, they'll post.
