inside the hex file i tried to attach is the code i modified,,,,,,,,,, but its got an integrity check,,,,,,,,,, crc,,,, md5,,,, checksum.
how to change the integrity check????????
You are joking, aren't you?
1 - you might be trying to attach a file to this forum, but would not manage. Not supported.
2 - why would you want to change a program that has an integerity check, without having the source code or tools to recreate this check? Changing licensing information?
3 - how would anyone be able to answer a question without having all required information?
4 - what school teached you that ",,,,,," is proper punctuation?
Surely?!
