    This is the official RLPack unpackme. Unpacking is considered correct if the unpacked Unpack.exe can unpack crackme.fsg.exe. You can not add ap0x unpacking engine .dll files to unpackme to make it work. You can only use things located inside the challenge archive. Due to the fact that Unpack.exe uses psapi.dll challenge will work only on NT systems. The first one to unpack the official unpackme will get RLPack Full Edition - Personal license!

    I have repeatedly been asked for a next step up from the keygen tut in the newbie series (#36). I finally have found the time to do so. The attached keygenme (see below) is supposed to be accessible for and aimed at newbie level till intermediate (newbie level having understood tut#36, now wanting to try the next level). Rated 2/10. Goal was not to make something difficult, but it will require a good understanding of how things work anyway. I'm awaiting your solutions here and will post mine with commented source (asm) in a couple of days. Success! lena151. lena151__s_KeygenMe_1.rar

    Sorry for starting this topic, but I'm on writing a tut about a generic method for unpacking all .NET craps. I wanna test more than 4 Unpackmes prepared by Teddy. Is there any packer instead of NSPack and Refractor?

    Unpackme#8 Just manually unpack. First timers may need to chew a little on this. I haven't made it difficult though : it's meant as a challenge only for those a little better than complete starters Enjoy. lena151 [EDIT] : It may fail to run on non NT-based systems though.
