    An 01 code means to write a 16-bit value at the specified address:

    01XXXXXX
    0000VVVV

    0103337C
    00000009
    --->
    write 0x0009 at 0x8C03337C in memory

    For a file patch, most likely you'd write 0x0009 at 0x2337C in the game binary.

    Ok, so I backported the code of ecco to the pal version.
    It is the same array of bytes its just located in a different position.
    Offset 3F577EF8 track5.bin

    The actual array of bytes is the same so you should look for this F7 89 03 65 and repalce it.
    I've noticed that most codes are for the japanese version, Can someone post the array of bytes for Le mans 24?

    Ok, so for those that are struggling finding the correct AOB or have a different version of the game, for the pal version of LE MANS 24h you need to replace these values to run the game at 60 fps.


    Code:
    FIND
    02 70 5A 0E 03 3E 1C 8B 44 D0 0B 40 06 E4 43 D3 C3 65 60 75 33 60 CE 01 50 E4 52 65 41 C7 08 F1 53 60 50 70 02 60
    REPLACE
    01 70 5A 0E 03 3E 1C 8B 44 D0 0B 40 06 E4 43 D3 C3 65 60 75 33 60 CE 01 50 E4 52 65 41 C7 08 F1 53 60 50 70 02 60
    
    FIND
    00 00 F0 41 3C 03 00 00 40 DC 1B 8C 44 03 00 00 40 03 00 00 1C 71 9D F0 0A F1 01 E0 F2 61 20 71
    REPLACE
    00 00 70 42 3C 03 00 00 40 DC 1B 8C 44 03 00 00 40 03 00 00 1C 71 9D F0 0A F1 01 E0 F2 61 20 71

    This is awesome! As expected, most don't run very well on real hardware but Toy Racer in particular seems to work flawlessly. At least in practice races anyway. Haven't tried it with other players yet.
