Like I said, I need more info. What's your wanted delay and seconds and what results are you getting instead?
my delay is 2332 for the time of 05:00:50 and I set the DS to 04:59:00 and I am getting anywhere from 1 second to 9 seconds off of my actual delay second. I have been trying for a while too and I know I have to be pretty close to hitting the a button when the timer is at zero.
Also, I have an DSi AR and if I use it to start the game am I suppose to hit a on the first timer at the boot game with codes menu?
