i know that every other minute it moves the left statue to get up on the left side and you need to get bat form to get through the center..... well how do you get on the right side is there a certain time? or what?

oh and how do i open the gate to the underground garden with alucard on the psp version

To get into the right side of the clock tower, grab the stopwatch subweapon (it's nearby in one of the neighboring rooms). Use the stopwatch in the clocktower, and for the allotted time of the time-freeze, the statue will move.

To get into the lower dungeon (resurrection chamber), you need to find the gold ring, and silver ring, then equip them both. I believe the silver ring is in the room Maria is in, that you have to get the spikebreaker armor to get in to. (top left area of castle, long hallway that leads to nowhere.....how the heck did Maria even get in there?). The gold ring, can't remember the exact location, but it's a dropped item after encountering the Succubus in the cursed coffin-save point zone. I know it's in the lower portion of the castle somewhere, just not too sure. It's a glowing purple coffin; entering it triggers a dream cutscene. After killing the succubus, the gold ring is dropped on the floor.
