Action Replay for GameCube: Still Works, But It's a Collector's Item

Yes, it worked — back when GameCube was current. Today, buying one is a collector's move.

Reality Check

• Availability: Discontinued. Only secondhand (eBay, retro shops) — prices $80–$200+.
• Compatibility: Not all games supported. Requires matching disc region (NTSC-U/J/PAL) and specific AR version (v1.0, v1.14, etc.).
• Cheat databases: Community-maintained lists (CodeJunkies, GCNCheats) are frozen circa 2007. No "new" codes.

Modern Alternatives

• Swiss / GCLoader (GCVideo) — Homebrew on modded GC/Wii; loads ISOs with built-in cheat support (Action Replay / Gecko codes).
• Dolphin Emulator (PC) — Native AR/Gecko code support, save states, HD rendering.
• GameShark — Similar device, same scarcity issues.

If you just want to play with cheats, Dolphin on a modest PC is cheaper, easier, and better preserved.
