JM has indeed a CRC check. Too bad they didnt use it to detect bot, but just to detect corrupted client...

CRC is a way of calculating a value based on doing some math with the bytes that make up a file. If you change a byte, the CRC value calculates differently for that file. So it IS used as a primitive way to detect unintentional changes to a file... such as when you transfer a file and have some corruption occur. It is NOT, however, a method of detecting ANY change to a file. If you need to change a byte in sro_client.exe but you still want the CRC to calculate the correct value, all you have to do is find another byte you can modify to offset your original change (like maybe a byte in a useless text string).
CRC as a bot detection device =
fail.
JMax as a customer torture device =
success.
