    One more fish to fry P.S: As always, a keygen is the only accepted solution here, feel free to make a tut for others if you like. Patching is NOT allowed, wanna patch something? look for a [patchme] or a [crackme] instead. If you decide to code a keygen, try to keep your asm ripping techniques to a minimum if possible.

    I have played a little with invalid metadata... Who can completely deobfuscate this? The keygen isn't mine, it is written by Mr.Haandi; i only used as a random exe to protect. The goal is deobfuscating, not cracking nor keygenning. DeobfuscateMe.rar

    UnPackMe · Started by HellSpider,

    Hi. Attached package includes 2 unpackmes. One of them uses a TIGER (Black) VM and the other uses a FISH (Black) VM. There is not really anything to unpack, the goal is rather to devirtualize the VMs. The virtualized functions are quite small: ~20 ASM instructions. The virtualized function executes when you press F1. Unpackme is coded in MASM. unpackme_cv_2.0.3.0_demo.rar
