Ultrakill Old UI

Brings back the look of the old ULTRAKILL UI on the current version. It only changes how things look; menus, shops and saves work exactly as before.

What it changes

Title screen

• Classic wide logo at the top and the old centered button stack (old sizes, spacing and button style)
• Old boxed DISCORD / TWITTER / YOUTUBE buttons
• Removes the V1 art, circuit background, border and terminal text from the main menu, so the 3D scene shows behind it again

Menus

• No V1 body art on the difficulty screen; the info panel on the right only appears while you hover a difficulty
• Chapter select keeps the dark panel but drops the circuit pattern

SmileOS terminals (shops and Cyber Grind terminals)

• Black panels with white outlines, --TITLE-- style headings, uppercase menu font
• Red window bars, window buttons and the Smile logo are hidden
• Buttons highlight red like the old terminal; the song list hides the "UNLOCKED" line

Installation

Install with a mod manager (r2modman or the Thunderstore Mod Manager). BepInEx is installed automatically as a dependency. To remove it, disable or uninstall the mod; no game files are changed.

Notes

• Everything is applied at runtime when menus and terminals load, so the very first frame of a screen can occasionally show the default look.
• If something looks wrong, check BepInEx/LogOutput.log for lines starting with Ultrakill Old UI.
• If Japanese/Korean/Chinese text shows as empty boxes in terminals, install the separate CjkFontFix mod.
