Whew. That was a very difficulty but good crackme. I've learned A LOT while trying to crack this and there probably still is a lot to find. Without giving too much away: I wrote a tool to recreate some of the "missing" code.

xmaple555 on 3:55 PM 09/16/2021: post a comment to record I have solved this crackme.
btw, the final letter of key involves too much calculation process. I think it is too much.
Elvis on 1:31 PM 09/17/2021: @xmaple555: I remember I just change a bit in last letter check. You can calculate it easy with script :)

so easy
PastorJimColerick on 7:34 PM 09/17/2021: @rippy you didnt solve shit retard you just patched some bytes. Generate the key yourself so that it works out of the box.
PastorJimColerick on 7:36 PM 09/17/2021: @rippy plus you also didnt get the credit screen and it still says wrong key
rippy on 3:29 PM 09/20/2021: @PastorJimColerick stfu nn ur opinion doesnt matter in a real world scenario no one tells the rules so stfu idiot retard shit kid
PastorJimColerick on 11:01 PM 09/24/2021: @rippy You are a shit cracker and it shows
Elvis on 9:14 AM 09/25/2021: @PastorJimColerick: Just ignore him. It's not worthy. BTW seem that you also solve this crackme. Congrats :)
nassimorg09 on 11:09 PM 12/15/2021: I have solved the debugger detection but I didn't get the flag I need some help around here
Elvis on 7:24 AM 12/16/2021: @nassimorg09:Good to see you have bypassed some anti debug tricks. You're still in the begin at solving this but good move. You might want to dig to how does crackme actually work. Hope someone can share there solution so other people can learn from it.
