TODO:

  - I'm playing samples with a DAC, but they could be ADPCM
  - find correct high-scores table for 'amazon'


Stephh's notes (based on the games M68000 code and some tests) :


1) 'terracr*'

  - Each high-score name is made up of 10 chars.


2) 'amazon'

  - Each high-score name is made up of 3 chars followed by 7 0x00.


3) 'amatelas'

  - Each high-score name is made up of 10 chars.


4) 'horekid*'

  - Each high-score name is made up of 3 chars.

  - There is a "debug mode" ! To activate it, you need to have cheats ON.
    Set "Debug Mode" Dip Switch to ON and be sure that "Cabinet" Dip Switch
    is set to "Upright". Its features (see below) only affect player 1 !
    Features :
      * invulnerability and infinite time :
          . insert a coin
          . press FAKE button 3 and START1 (player 1 buttons 1 and 2 must NOT be pressed !)
      * level select (there are 32 levels) :
          . insert a coin
          . press FAKE button 3 ("00" will be displayed - this is an hex. display)
          . press FAKE button 3 and player 1 button 1 to increase level
          . press FAKE button 3 and player 1 button 2 to decrease level
          . press START1 to start a game with the selected level
    FAKE button 3 is in fact the same as pressing simultaneously player 2 buttons 1 and 2.
    (I've code this that way because my keyboard doesn't accept too many keys pressed)
