Sonic Cuphead Mania

A local remix draft built on Silksong: Cuphead Edition.

• Cuphead remains playable through the existing remix: Cuphead's real character frames, Peashooter, EX shots, sounds and combat are prepared from the player's own Cuphead install.
• Sonic Mania contributes Sonic's real player sprite sheets and animation metadata, read from the player's own Data.rsdk at launch. Sonic replaces Cuphead's visible player sprite.
• Ground movement adds acceleration and a higher speed target; Silksong's air movement, dashes, camera, maps, progression, enemies and bosses remain the host game's.
• Intended scope is the complete Silksong campaign. The current add-on does not reproduce Sonic Mania's stages, rings or monitors.
• Single player. Nothing from Cuphead, Sonic Mania, or Silksong is included in the package.

Requirements

Hollow Knight: Silksong, Cuphead, Sonic Mania, and the original Cuphead in Silksong remix. Melty installs BepInEx 5 for Silksong. On first Play, Cuphead's own files are prepared under Melty's managed Cuphead own-copy folder; Sonic Mania's own Data.rsdk is mapped into Silksong's managed own/sonic-mania folder. The Sonic sprite cache stays under the player's local application data.

Current verification

The add-on compiled against the installed Silksong assemblies. Sonic's Sonic.bin and player sprite sheets were extracted and parsed from the local Data.rsdk; Cuphead's cache preparer completed against the installed Cuphead copy. Melty's recipe validator reports valid, all five archive files are mapped, and one_click_check reports yes. A live game launch, visible in-game behavior, a gameplay screenshot, and the listing license choice are still outstanding. This is a draft, not a tested release.
