You at least have to beat the first GYM and receive the C-Gear.I just bought Black 2 and I decided to RNG for a TID/SID. From reading earlier post it looks like my calibration from Black 1 wont be the same in Black 2. How far in the game do I have to get before I can reliably find my games settings so I can RNG my TID/SID?
I'm not sure if TID/SID manipulation in B/W2 is the same as B/W1.
