Playing as Kafei in Majora's Mask (GameCube) via Action Replay: Not Possible

Action Replay codes cannot make Kafei a playable character in The Legend of Zelda: Majora's Mask on GameCube.

Why:

• AR Modifies Values, Not Code Flow: Cheats change RAM (health, items, flags). They cannot rewrite the player character controller, animation set, camera logic, or input handling—all hardcoded for Link.
• Kafei Is an NPC: His model, skeleton, and AI exist only for his scripted sequence (Sakon's Hideout, Curiosity Shop). No player control hooks.

Actual Ways to Play as Kafei:

• PC Emulation (Dolphin) + Mods: Community mods like "Play as Kafei" (by Garz on GameBanana) swap Link's model/animations. Requires Dolphin + ISO + mod install.
• Custom ROM Hacks: Majora's Mask: Kafei Edition (WIP) restructures the game around Kafei.
• Majora's Mask 3D (3DS): Same limitation—no official Kafei play. Mods exist via LayeredFS on hacked 3DS.

In Vanilla Game: Wear Kafei's Mask (obtained after his quest) to trigger unique dialogue and the "Kafei's Letter" cutscene—closest to his perspective.
