Editing info.pac in BrawlBox without the file size massively increasing?

[Lord Prosper]

So, I replaced some songs, and I tried to change the song titles (you know, make it seem legit), and my info.pacs file size like... almost tripled. I know it won't load due to size since I use Gecko OS, so... how do I stop it from getting that big?

use v0.66b

Thanks!
