integer properties:
-------------------

[trainers]              number of trainers

--------------------------------------------------------------------------------
release naming
--------------------------------------------------------------------------------

generally the release title/name should ONLY contain the actual name of the
respective game, and no other information. ("delta", not "delta +4HI")

now when the release title is displayed, some information from the properties
above are used to generate "scene like" names:

- first comes the game name
- if [preview] is true, then a minus sign is appended
- (space)
- if any trainers or any of the properties associated with a letter above is
  selected, a plus sign follow by all associated letters is added.
  - the number of trainers always comes first ("delta +4H" not "delta +H4")
  - as a special case, if only one trainer and no other properties associated
    with a letter is selected, the "1" after the plus sign is dropped
    ("delta +" not "delta +1")
- (space)
- if [release proper] is "100%" or "101%" the respective string is appended

if [auto naming override] is selected, the above does not apply and the release
title will shown as is. this is to properly represent release names that are
very hard to put into the above scheme ("delta +10HI 95%FIX")

 # = Instructions
 % = Intro
 & = Music
 - = Preview

 H = Highscore saver added

 No real standardization on this one, I've found both "+2H" and "+2+H". Also HI, 
 HIGH and HS have been used instead of only H.
 
 +M was for the in-game trainer like Levelskip etc. but hardly used anymore after 
    1990... Often people couldnt agreed if a levelskip meant +M or +1M which means 
    if they got 4 trainers some people ment it was +4M and other +5M.
 It is uncertain when they stopped using the +M / ++ way to mark trainers.
 
 +F or FX or FIX is also used for NTSC/PAL fixing

 +P or +PW = Password file

+R = REU
+D = docs
+I = ide64
+T = translated
+J = 3/4 player joystick compat

nostalgia didn't use +M for map, cuz it already means megatrainer from old times
