    Hi to everybody. Here is a small old year - new year present to fill those empty moments in this dark time of the year. Happy living to all. The unpackme was protected by a stripped down version of lARP 2.0 (lena151's Anti Rip Protector). Unpack/deprotect the unpackme and the first to succeed gains a kiss on the forehead from me (or perhaps this is a good reason not to try it? ) Success to all, lena151. lARP_2.0_Unpackme.rar

    Attached is an unpackme from my own protector, Ultra version. Though lARP v2.0 Ultra supports compression, I haven't done so for this UnpackMe. I added quite a lot of features in comparison with Lite, Standard and Pro versions. It might have become harder to unpack but that's why I coded in a messagebox + exit (warning for debugging or VM), which should be an excellent point of attack. The real stuff doesn't have this messagebox nor exit though (See previous versions). Unpack and tell me about its flaws. I want to explicitly thank my buddy jstorme for providing me with ideas, testing on x64 and to always have kept pushing me over the edge. I would not have continued…
