use an action replay to hack into the game and smash them.chances are they'll have a cheat for that.
sorry you can't move silver rocks. you have to get past a certain point first like beat the elite four or something like that
are black\brown rocks worth money
HM STRENGTH HM STRENGTH
in mount silver go up the waterfall rather than the rocks.
dark brown or black
Black to dark Grey, in most cause, though very rare to fine silver seams !

You use HM Rock Smash on smashable rocks.
to smash lil' rocks in pokemon black, u need rock smash which u get from the battle girl right at the bend at the entrance to pinwheel forest. HOPE IT HELPED:)
