So Ive tried tapping and holding the button but still cant get the 'sound' speed your getting on hits (especially on L2 boss.. is there a tech to fast fire?

Hello! Thank you for the comment. I think it's about practice. What version of the game are you talking about? NTSC or NTSC-J?

Im actually playing PAL... ill try NTSC-U but it seems that for example I dont get as rapid fire on bosses and its taking longer to kill bosses or dying as I cant get enough hits. Do you tap rapidly or hold the button on bosses?

I tap rapidly because holding the button doesn't give so much profit.

When I was fighting against the 2nd boss, I reset if I don't get the result I needed.
