How do I replace the result screen?

[JbBlaznnn]

I see many people have replaced their result screen and few to no guides on how to do it. Does anyone have an idea on how to change this?

Assuming you already use mods...
Since the results screen is a stage file, you'd put your replacement in your "pf/stage/melee" folder, with the name STGRESULT.pac.
You can find some new results screens at the Brawl Vault, it's the first thing under "Misc."
