Remove Dongle Checking on old 1997 DOS Program

I've mastered software reverse engineering/C/C++/C#/Java/Win API/Assembly programming and helped many customers. Especially, I've rich experiences of unpacking Themida/WinLicense, VmProtect, and other packing modules. I've also ever worked for online game maintenance, bug's fixing, and cheat and anticheat developing. And I have cracked a lot of dongle key(USB, Parallel, and etc) protection mechanisms. I'm sure I can fulfill your job successfully. I hope our collaboration to produce a good outcome that makes u happy. Best regards.

Hello. I can help you with this old app. Send it to me (executables or whole work dir) for analyze please.

Hello, This project looks fun. Does this program shows error if dongle is not recognized? If yes, I am happy to try to run it. For now in some controlled environment like DOSbox. Regards, Jakub Zawadzki
