I don't want any credits mate, I just wanted to help you. :)
And you don't have to start from the beginning again, RNG abusing on a flash cart isn't much different. Just make sure you don't have your game inserted when you want to edit the time. When you save your time, turn it off and put your flash cart in it. Start your game, but don't continue the save. When the first timer runs out, you have to soft-reset your game, and then when the second timer runs out, you get ingame.
