Ok, just reply to these question.
0. Can you make a save file of your game, preferably a save file compatible with action replay dsi or nds adapter plus. If you can do this I can help you extremely fast.
1a. How many roamers are currently roaming?
1b. Who is roaming and what were their save route?
*Note since the only way to verify the frame in Lance room is via roamer method, I'll assume that the you'll getting frame of 3 due to a roamer or 2(but I believe POJ already address that)
1C. What is the target date and time?
2. You have saved to be 1 step away from lance?
3. Can do you use eontime, pikatimer, or any other timer? If so can you hit high delays? Since this HGSS, I'll assume you are using a timer due to the normal delay being 488-500
4. Are you doing this from a cart or emulator?
I am a busy student and I play too much halo so I will reply back to this or another member will
