halisi:The core in Drive Galvan (?) has been used before, by a B-Daman called "Battle Phoenix". The rollers aren't there to increase rapid fire, they're too close to the marble, they increase power further.
Also, I read it as "Emblem CHARGE System", which leads me to believe that the emblems compress the core when pushed and cause additional resistance for the marble to be fired. That's also been featured in other B-Daman, specifically the Phoenix series from Super B-daman and Cobalt Saber Fire from Battle B-Daman.
This leads me to believe that Drive Galvan uses a "squeezing" method to create additional power.
