Please help with Super Mario Kart Code

Hi I'm trying to make a code to make it harder to get 1st place. All I want to do is make this address 7E13EB which is for the 3nd Computers speed to always be increased by 1 so if one normally becomes two if two three if three four. I don't want to freeze the address because the computer wont be going fast enough to make some jumps. This is the
code I made please help if you can. I tried to make the code so when time is not Equal to zero, Time address 7E0102,
increase this address by one 7E13EB so what ever value it would normally be on would always be 1 higher.

Explain the ASM you have or want to be executed plus where are you hooking your jump to the new routine? Also where is the free memory location that will hold your routine?

80E88F:22 JSL Control pad break point
80E890:E5
80E891:FF
80E892:FF jumps to our custom routine
FFFFE5:4A
FFFFE6:4A LSR
FFFFE7:4A
FFFFE8:4A LSR
FFFFE9:48 stores the current value of A to stack PHA
FFFFEA:AF LDA
FFFFEB:02
FFFFEC:01
FFFFED:7E address for time
FFFFEE:C9 CMP
FFFFEF:00 compares time to zero
FFFFF0:F0
FFFFF1:06 If It's equal to zero jump to address FFFFF8 or load next line if not
FFFFF2:1A INC A INCrease A
FFFFF3:01 By 1
FFFFF4:8f STA long Store Accumulator to Memory
FFFFF5:EB
FFFFF6:13
FFFFF7:7E 3nd Computers speed address
FFFFF8:68 PLA Pull Original Value from stack to Accumulator
FFFFF9:6B RTL Return from Subroutine Long

Ok Helder I'm trying to make the 3nd computers speed one higher then normal all the time when time is not zero. My friend I hope you're well. take care

This is one of the codes I made to make it harder to get 1st place

81B9A822 22=JSL jumps to address C09300
81B9A900
81B9AA93
81B9ABC0 C09300 free space in rom
C093004A
C093014A all this
C093024A
C093034A part 4A=LSR puts back what was replaced
C0930448 48=PHA stores the Accumulator value to stack
C09305AF AF=LDA load to Accumulator address
C09306E6
C0930713
C093087E 7e13e6, address for 3nd computer position
C09309C9 C9=CMP compares what is in Accumulator
C0930A00 to zero
C0930BF0 F0=BEQ jump to address C09313
C0930C06 if address 7e13e6 value is equel to zero if not load next line
C0930DA9 A9=LDA load in to
C0930E04 Accumulator four
C0930F8F 8f=STA Store Accumulator value to
C09310EB
C0931113 address 7e13eb for 3nd computer speed
C093127E
C0931368 68=PLA Pull Accumulator/ Restore the Original Value of Accumlator Back from Stack
C093146B 6b=RTL Return from Subroutine Long/Return to where we jumped from

May have small graphic glitches


Thank you Helder for helping me learn to make this type of code
