Do You Need a Power Board for Action Replay on GameCube? No — Just the Memory Card

No. The Action Replay (Datel) for GameCube is a Memory Card (59 Block / 1019 Block) that plugs into Memory Card Slot A or B. No external power, no "power board".

How It Works

1. Insert Action Replay Memory Card into Slot A.
2. Insert Game Disc.
3. Boot console → Action Replay Menu loads (before game).
4. Select Add New Code → Enter code manually (A/B/X/Y, D-pad, L/R, Start).
5. Or: Load Codes from Disc (AR comes with code disc / SD Media Launcher).
6. Select Start Game → Game boots with cheats active.

What You Need

• Action Replay Memory Card (disc version includes card + code disc).
• GameCube / Wii (backward compat).
• Game disc.
• No extra hardware.

Modern Alternative: SD Media Launcher / Swiss

• SD Media Launcher: Disc + SD Gecko (Memory Card → SD adapter) → Load homebrew (Swiss, Nintendont) from SD. Runs ISOs, cheats, homebrew.
• Swiss (Homebrew): Boot from SD Gecko / GCLoader / Xeno / Qoob. Built-in cheat engine (AR codes), force video, region-free.
• GCLoader / XenoGC / Qoob Pro: Drive replacement / modchip → boot ISOs from SD/HDD, built-in cheats.

Original Action Replay: Just the memory card. Plug in. Enter codes. Play. No power board.
