Hacking Chu Chu Rocket GBA

[aceofbass21337]

I have EZ Flash IV. All my other games work fine. I put Chu Chu Rocket through the ez client and all i get when i start the game is a screen with an exclamation mark. How do i get the game to work. Im new to all this so if patching is required please make the description as simple as you can. thankyou
