Making my Sony CRX320A 52X all the time

i recently purchased a crx320a combo drive and am wondering if i can flash it with a lite on firmware to make it 52X speed all the time instead of pressing the eject button for 5 seconds to turn this feature on. i did some searching a seen that some have done this but i am not sure where to download the firmware from and i have no experience at hacking firmware. could somebody please point me in the right direction?? i seen codeguys has a patched firmware to increas the rip speed but i am more interested in turning on the 52X feature. thank you

just take the 5232k firmware:

i tried that firmware and it told no matched drive for that firmware

ok, download it here:

thank you very much, successfull flash. 52X all the time now
