Hello all!

I know its old game, still running but i would need some help from someone who completed level 6 of this reversing/hacking..cracking course..
The main problem is that site is still running but admins and most of ppl are gone..


I am stuck on decrypting txt files which i get from *.m*.. i dont know how to get readable txt..

solutions hints can be pm to me...

Ps: for everyone else which didnt try it yet.. go for it..

thx NEO
