Erm, as far as i know, each vertex can be affected by 4 bones maximum.
Each vertices holds a weight, you can only access this by reading the actual .b3d file format bit by bit, for example:
Vertex1: weight of bone1 = 0.2
Vertex1: weight of bone2 = 0.2
Vertex1: weight of bone3 = 0.4
Vertex1: weight of bone4 = 0.2
On vertex 1, the bone3 would have the greatest influence on that vertex, should it be transformed .
