RAM map (Boktai 2)

This is the RAM map for Boktai 2 (U).

EWRAM

Address	Type	Description
0x0200184c		Is full moon (*0x030047f6 == 4)
0x02001469	i8	High-level solar sensor state: 0=disabled, 1=waiting for enable, 2=enabled. When going through a screen transition, this will change from 2 -> 0 -> 1 -> 2.
0x0200146c	i16	High-level solar sensor: Calibrated level (0=dark, 140=max brightness. Calibrated level = calibration - raw level, then clamp to 0-140)
0x02001470	i16	High-level solar sensor delay: Used for delaying the state 0 -> 1 and 1 -> 2 transitions
0x02002464	i32	Total EXP until next level
