!RAM !! Purpose
|-
|0x0006 || Part of an instruction for "copy protection". $E5 on checksum failure. $00 to bypass.  "Correct"/non-hack value unknown.
|-
|0x0015 || Used for assigning area to objects?
|-
|0x0060 || HP target value for stat increase during level up
|-
|0x0611 || Looks like the first EXP byte, but changing it even mid-battle will result in insta-death.  Anti-cheat?
|-
|0x0818-B || The X and Y coordinates, stored strangely; see below
|}
 
===Coordinates===
The coordinates in RAM to not correspond to coordinates in the rest of the game.  To convert it, run this Python code (in this example, bytes $818-B are `80 19 C0 2D`):
 
<pre>
# replace with the values from the RAM
ram_x = 0x1980
ram_y = 0x2dc0
 
real_x = ((byte1 << 8) | (byte0 & 0xC0)) >> 2
real_y = ((byte3 << 8) | (byte2 & 0xC0) - 0x2000) >> 2
</pre>
 
=SRAM (save data)=
Due to something that is not figured out yet (checksum?), so you can only edit things by using a save RAM editor on a live game, otherwise it will erase your save data.
