r0B on 2023-03-21 03:47: hi 7T7, thanks for the keygenme! although not a solution per se, here is my keygen: https://jsfiddle.net/Ldv8sqj2/

7T7 on 2023-03-21 17:16: Awesome.. I am so happy to see your work. Great Job. Can you please explain the method you have approached for this keygenme ? Its only for my learning purpose : ) I don't have any experience with keygen solutions. Just curios to learn your approach over this.

GOTT33 on 2023-03-22 10:06: It is not a Success Crackme, rather a confusing Code, take your batter to 100, then emulate it to 60, just a patching game :)

alexisreen0 on 2023-03-31 14:18: Do you allow patching the debugger and battery checks?

7T7 on 2023-04-03 03:58: Hi alexisreen0, Thank you for your time for this keygenMe. Here we are only looking for an Keygen. You can bypass all the restrictions planted in keygenme. But, finally we need an keygen.

ISquishWorms on 2023-04-18 15:43: Hello, I sent in an Excel keygen that I made for this crackme but it was rejected. Can I ask why it was rejected so that I can provide you with the solution that you are after. I did test my Excel Keygen and it seemed to work so not sure what else I need to do.

7T7 on 2023-04-18 19:30: Hi ISquishWorms, May be your solution were rejected by administrator. Its not verified by me.

ISquishWorms on 2023-04-19 21:15: Hi 7T7, thank you for replying. I am new to this site, I did not realise that it was the admin that did the checking of the solutions. Is there a way to find out why it was rejected do you know? Maybe a way to contact the admin? If they reject a solution it would be useful to be given a reason why as I am not sure what I need to do now so that my solution will be accepted. The only reason I can think of is maybe because I made it using Excel rather than using a language such as C to code it. I never saw that as a requirement though. I can code my solution in C if I knew that is what is required. Oh well... My Excel solution works as far as I can tell, I have tried several different keys produced by it.

7T7 on 2023-04-20 18:13: Hi ISquishWorms have you read https://crackmes.one/faq ?

ISquishWorms on 2023-04-21 14:18: Hi 7T7, yes, I have read the FAQ when I joined the site. I did note that that it said that simply submitting a Keygen would not be good enough and an explanation should also be included. Worth a try right? :) It will mean going through the assembler again though as I did away with most of my notes. I will consider that a lesson. In the details that you provided with your crackme you explain that this is a Keygen exercise. I probably took that a little too literally, so maybe I should try and submit my solution again along with a better breakdown on how I came up with my solution.
