Yu-Gi-Oh 5Ds World Championship 2010 Reverse of Arcadia Security Help

Hi, I just downloaded the "Yu-Gi-Oh 5Ds World Championship 2010 Reverse of Arcadia" ROM. So I was playing it, and got stuck in the Security House; where you have to get your deck, Crows deck etc. But I really don't know how to oen the SouthWest door. I was in ALL of the rooms except for that one. What Should I do? Please help, and Thanks.Arcade Star :P

soon as you enter go to the right get your deck and crows then go back to crows place
