If I'm understanding your question correctly, you have to be in game to soft reset. You will literally be looking at your little dude with a beret. When the clock reaches your desired time, you hit the Start + Select + L + R keys all at the same time, and mash a as fast as you can.\
3. Start your game and keep Start + Select + L held then press R (these are the buttons hit to soft reset the game) exactly when the clock reaches the next minute. Hit A as fast as possible until you enter the game world. You will want to note the exact time that you soft reset the game.
whats it mean by this part
do i open the ds to where it says continue then press a once the clock reaches a minute
