Setting Up The Action Replay DSi
Connect your Action Replay DSi device to your computer via the USB cord that came with the peripheral.
Open the "Action Replay Code Manager." The software will automatically detect your connected card.
Right-click in the "My Codelists" panel. A list of options will appear, similar to if you right-clicked on the desktop.
Click "Add new cheat." A new panel will appear.
Enter a cheat code for "Sonic Rush Adventure" (see Resources). The game has several codes, all of which alter the gameplay in some way.
Give the cheat a name and press "OK" to save the cheat. The changes will automatically be saved to your connected Action Replay DSi card.
Playing "Sonic Rush Adventure" With Action Replay DSi
Attach the Action Replay DSi device into your Nintendo DS handheld. The card should fit snugly, and the "Sonic Rush Adventure" card should be able to plug into the slot on the Action Replay card.
Attach the "Sonic Rush Adventure" card with the Action Replay DSi card via the device's open slot.
Start the game and the Nintendo DS console.
Activate the cheat code's trigger, if necessary. Many cheat codes have to be activated by pressing a series of buttons, such as the left and right trigger. This trigger, if necessary, will typically be described in the name of the cheat code.
