BASIC CONTROL CODES for EB0:

01 - new line
03 - Wait for input, prompt
Note: the absence of a prompt at the end of a string will
not cause the window to automatically close, like in EB

NAMES OF STUFF:
21 - used for names of stuff:
 21 78 74 - display Ninten's name
 21 B8 74 - Ana's name
 21 F8 74 - Loid's name
 23 38 75 - Teddy's name
 21 89 76 - display favorite food
 21 0A 67 - usually, this displays Ninten's name
 21 0A 67 is definitely Ninten's name, as far as I can tell:
 "a voice is speaking into 21 0A 67's mind..."

It seems odd, but 21 78 74 and 21 0A 67 seem to both do the
same thing (display Ninten's name), and they're both used in
game text.  There must be something else.  Just a thought,
but 21 0A 67 could be the name of the currentlead character
(if Ninten dies)

21 00 6D - The recipient of an action, item, etc. Depends on context.
           Used to show the name of a person who is in the hospital,
           in some places.

21 04 6D - This seems to be the name of an item being used or action
	   being executed.

21 20 6D - the user of an item, or executor of an action. Again, depends
           on context.

These work something like this: "21 20 6D (user) gave 
21 04 6D (item) to 21 00 6D (recipient)"

21 24 6D - Another thing for an item being used, or something.
21 20 74 - Another weird thing: "Certificate # @21 20 74"
           (note: I can't remember where this is from, it's been
	   a while since I played EB0)

MONEY-RELATED STUFF:
23 12 74 - ATM balance (I think)
23 15 74 - Something like the amount your dad has deposited
	   in your account since you last called him. (?)

23 2A 00 # 00    - I think this is used a lot for the price of an
		   item or service.  - used like this:
                   I'll give 21 0A 67 a prize of 23 2A 00 02 00
             	   (I think this is the mayor...)

23 2A 00 # 00 is used again in context of a price for something:  
"Want to buy it? How about $ 23 2A 00 20 00 ?"  I think the number
between the two 00's is an argument of some sort, seeing how it's used.
It's usually 02, or 20, sometimes.  I'm not sure tho.
