Frogger for the Lazies (an unknown Parker function)

[Zeelay]

(I hope that I am in the right place to post this)

 

While I was hacking Parker's Frogger, I found these interesting lines :

 

       LDA    $DE     
       CMP    #$10    
       BNE    LF0E9  

       LDA    INPT4

       BMI    LF0C0   
       LDA    $DD     
       ROR            
       BCS    LF0BD   
       LDA    INPT5   
       BMI    LF0C0  

 

I noticed the presence of INPT4 and INPT5, which means that the joystick's buttons are been watched.

It is stanged, because they shouldn't, since the games only use the four directions.

 

Then I understood that when the games ends and the music starts ($DE = #$10),

if you press the button, then the game starts again...
and you don't have to bend to your console to press GAME RESET.

In a two player mode, both players have to press their buttons to do so

(This cannot be done when you switch on the console).

 

As far as I know, it has never been mentioned in any booklet manual.
