   - Each high-score name is made up of 3 chars.
 
-  - There is a "debug mode" ! To activate it, you need to have cheats ON.
+  - There is a "debug mode" !
     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 !)
+          . press player 2 button 1 and 2 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 player 2 button 1 and 2 ("00" will be displayed - this is an hex. display)
+          . press player 2 button 1 and 2 and player 1 button 1 to increase level
+          . press player 2 button 1 and 2 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)
