Legally you can't as far as i know (if you're talking about customizing the logo itself in the start menu)...Asrielly wrote:
Recently, I've seen about 2 or 3 people who has this: On their main menu, their osu! logo is modified, so instead of a pink background osu! logo, they somehow modded it into the osu! logo with a background of their choice, including anime pictures and stuff...
Has anyone got an idea on how this could be done or if it's not possible, explain what was going on?
Pretty sure You'll get banned if You've been found out customizing the UI outside the skin folder elements You can customize (like the UI Fonts, non-supporter background, etc.)
But if You're talking about the background under the logo, add a "menu-background.jpg" inside your skin folder (and You have to become an osu!supporter to activate it)
