Once again, I use model edits to improve some already great hacks.
The download for Peach’s umbrella is a BRRES package and must be inserted using Smash/Brawlbox. First use Smash/Brawlbox to open the .pac or .pcs file of the Peach hack you to apply It to. You will see two texture data BRRES packages, Right click on the bottom one and select replace. Then select the Peach umbrella BRRES file you downloaded and that should be It. Save It and enjoy!
