Freeway; Would Like to add more time

[Atari2600VCS]

Hi all, Freeway is my all time favorite game, but it doesn't last long enough. Could someone make Freeway with a longer timer? Maybe three times longer than the normal time? Or could someone tell me what the address is and I could change it? Thanks for any help.

       LDA    $88     ;3 (red color/screensaver)
      LDY    $E6     ;3 Check game state
      BNE    LF05D   ;2 branch if game over
      LDY    $E9     ;3 load timer (high)
      CPY    #$20    ;2 = 32?
      BCC    LF055   ;2 branch if less
      INC    $E6     ;5 bump game state (game over)
LF055: CPY    #$1E    ;2 timer (high) = 30?
      BCC    LF05D   ;2 branch if less
      LDA    $81     ;3 use framecounter for color
      AND    $87     ;3 adjust for color/B&W
LF05D: STA    COLUP0  ;3 store to both sprites
      STA    COLUP1  ;3 ..

 

To triple the amount of time, change the #$20 at $F050 to be #$60. However, this does not change the amount of time before the scores begin to flash. You can change that at $F056 (you'd alter the #$1E to #$5E at $F056 in this case to make the score flash about 5 seconds from game end).

Thank you Nukey Shay, that's awesome, you're the best! I can now run like a chicken in a marathon.
