I did this back in the year of 2003, which was my first GBA game ever. The SNES version of this game I've beaten several times in the past, so I knew how to get 100% of the game (except the new added secret stages in the GBA version, which i've also archieved later). So, after beating the game normally 100% with many tries, I tryed to do another challenge to get No. 1 at the game selection screen, which is shown in the video. So I had an idea, by using the trick to soft reset the game every time I'd lose a try. Though, I was still forced to do each stage in one attempt and also getting 100 points. I was very suprised that it worked and wondered, if somebody ever did this before, using this method?
