hey guys thanks for help in advance. I run a grand chase private server for myself. Im trying to extract KOM files to edit the server. Before i stopped working on it BMS used to work and extract the files.
I get the error now. " unknown algorithm 5e675234 at offset 0x0000000000005c6c (0 -> 207), contact me"
Not sure why ill post the script i got with the program that used to work... If you can find whats wrong i appreciate it... Its stressful

Do you mean that the script 0.1.1 you post works on your file and the current 0.1.3 doesn't?

Or do you mean that older versions of quickbms.exe worked and now no longer?

If you have a sample kom file that gives you that problem I can check it.
