Here's why:
* AceKard 2i and Action Replay are different devices. The AceKard 2i is a flash cart designed to play games from a microSD card, while an Action Replay is a separate device that uses codes to modify game behavior.
* Different functionalities. The AceKard 2i relies on custom firmware and game backups to play games, while Action Replay works by injecting code into the game's memory. These are incompatible systems.
To use cheats with your AceKard 2i, you'll need to:
1. Find cheat codes specific to the game you want to use. Websites like GameFAQs or forums dedicated to the specific game can help you find codes.
2. Use a cheat code manager: Some AceKard firmware versions allow you to create custom cheat codes for certain games. You can find instructions for doing this on the AceKard forums or websites.
3. Use a separate device: While this isn't ideal, you can consider purchasing a separate Action Replay device to use with your Nintendo DS.
Remember that using cheats can sometimes be harmful to your game save files or cause game instability.
