Help On Mario Kart

[HPdesk]

Is there any cheat of Full Speed for Mario Kart Super Circuit for GameBoy Advanced ??? cause my brother spent only 39 secs to finish the peach circuit. My best time is 51 secs. He told me that he did that running at full speed all the time. But how ??? I look over the internet, but this cheat is only for N64.

HOW CAN I DO IT ??? DOES ANYONE KNOWS ????




THANKS
