    Again, trying to be helpful:

    For Infinite Offensive Play Timer:

    Original assembly code:

    >00:B3DE:85 B1 STA $00B1 = #$1B
    00:B3E0: D0 04 BNE $B3E6

    Your code:

    00:B3DE:EA NOP
    >00:B3DF:B1 D0 LDA ($D0),Y @ $019F = #$00

    Proper code:

    >00:B3DE:A5 B1 LDA $00B1 = #$1B
    00:B3E0: D0 04 BNE $B3E6

    XVSUTLSE

    address: 0xB3DE
    compare: 0x85
    value: 0xEA

    becomes

    SXSUTLSA

    address: 0xB3DE
    compare: 0x85
    value: 0xA5

    For Infinite Defensive Play Timer:

    Original assembly code:

    >00:B3C4:85 B2 STA $00B2 = #$0A

    Your code:

    00:B3DE:85 EA STA $00EA = #$00

    Proper code:

    >00:B3C4:A5 B2 LDA $00B2 = #$0A

    XVSUYLOU

    address: 0xB3DF
    compare: 0xB1
    value: 0xEA

    becomes

    SXKLGLSA

    address: 0xB3C4
    compare: 0x85
    value: 0xA5

    Our final codes would be:

    SXSUTLSA Infinite Offensive Play Timer
    SXKLGLSA Infinite Defensive Play Timer

      Yeah, sorry about that. This was before learning about not using EA as an opcode. Thanks for the revision. (-_-; )
