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

Stat struct

Access this struct via 0x030046a0. Size: 0x958 bytes. See also: Inventory (Boktai 2).

Offset Type Description
0x28 i16[6] Stats (HP/ENE/VIT/SPR/STR/AGI) - updated from *0x03002be0 + 0x364 on screen transitions
0x30 i16[3] Django(& Sabata?) position
0x40 i16 Current level*
0x42 i16 Allocatable stat points
0x46 i16[5] Weapon skill EXP (Sword/Spear/Hammer/Fists/Gun; 100 exp = 1 skil level)
0x50 i32 Total EXP
0x54 i32 Magic inventory (bitmask)
0x70 i16[48] Item inventory slots
0xd0 i16[48] Item inventory durability
0x130 i16[16] Key item inventory
0x150 i16[32] Protector inventory
0x23a i16 Solar bank interest rate (stored as (1+r)*64, e.g. 14.0625% = 73). Defaults to 65 when starting a new game. When the date changes, the rate will change to 65 + (IGT_frame_counter XOR RTC_seconds) mod 13 (effectively uniformly distributed in the interval [1.5625%, 20.3125%]).
0x242 i16 Current map ID
0x250 i16 Current player form (Red Django/Black Django/Bat/Mouse/Unused/Sabata)
0x254 i16 Current area ID
0x24c i32 Current map's init script ID
0x2b4 i32 IGT frame counter for this save file

0x2c4 Sabata: Kaamos progress
0x2c8 Django: Kaamos status
0x2ce Sabata: Kaamos status
0x3d0 struct[16] Weapon inventory
