NewGame 25489 LD A,3 Write starting lives to Player_Lives (duplicate of 24566 - possibly so POKEs would appear to not work?)
25491 LD (24125),A
This entry point is used by the routine at HandlerCup.
NewGame_ResetCups 25494 XOR A Set the number of cups collected to 0.
25495 LD (24124),A
25498 CALL RandomiseCups Put the cups back at new positions using RandomiseCups.
Reset miles and time.
25501 LD HL,24109 Point HL at the miles (Miles).
25504 LD B,7 Set the byte counter to 7 to cover the miles and the time.
GameInit_Reset 25506 LD (HL),0 Clear a byte of the miles and time.
25508 INC HL Move on to the next byte.
25509 DJNZ GameInit_Reset Decrease the byte counter by one and loop back to GameInit_Reset until the miles and time have been cleared.
This entry point is used by the routine at GameOver.
Set up a new car.
