I picked up the pcb after deciding to let go of Ghosts and Goblins, because even the thought of trying to get the 1 loop clear is unappealing, two years after I stopped playing it.
Raiden II is just so enjoyable, so fulfilling when you get it right, that i just don't want to take it out of the cab for any reason.
I'm shooting for the 1cc and my skills with old school games is such that I can see it happening, but really, only time will tell. High score right now is a paltry 871,630, but progress is coming swiftly.
