Description

I lost my friend Jack...help me to find him!

S01den on 8:27 PM 03/25/2019: Hey, can we patch the program ?

sw33tLie on 10:02 PM 03/25/2019: Yes patching is allowed...be creative! You just have to force the console to show the right thing.

Lawliet123 on 10:28 PM 03/25/2019: I sended a solution. This is my old nickname, new is ALWIEZ.

sw33tLie on 4:01 PM 03/26/2019: [SPOILER ALERT] Nice solution, really well written. Your method works for sure and it's correct, but i would have done it in a different way. If you check the assembly you will see that the right subroutine that shows the correct string is basically an unreferenced function. I would have patched the call instruction from the main() function to call it instead of the wrong string subroutine. That said, thanks for submitting it anyway :)
