Description
Can you make a CoreWars warrior that always loses, no ties?
Your opponent is the Imp. The source is available [here]. If you wanted to pit the Imp against himself, you could download the Imp and start your own corewars server
Note: This challenge launches an instance on demand.
Ok so for this challenge I had to learn what CoreWars was, and its apparently its a game between two programs that are written in RedCode which is a pseudo-assembly language.
Our mission is to lose to the program provided 100 times.
After trying out what will happen if I provide the same code to the server, we just ended up with 100 ties.
So, I just deleted the only instruction that does operations in the game and the warrior
;redcode
;name Imp Ex
;assert 1
end
I lost which gave the flag:
picoCTF{your flag}

can explain more litely how you cracked the program
Can you be more specific?
i read you deleted the the only instruction that does operations ,do you mean these lines :
;redcode
;name Imp Ex
;assert 1
end
if so there is nothing left tho!
I see I deleted the operator of mov, the initial code is like this:
I deleted mov 0, 1 only since we needed to loss 100 time.
