    It's saturday night party time! Crack open your laptop and head to the dancefloor w/this latest challenge wooooo hoooooo yeaaahhhh!!Intro:The original project was done by a team who's coders I've learned a lot from and respect.

    Hi. I made some UnpackMe styled executables protected by the latest demo version of CodeVirtualizer (2.0.8.0). Each executable contains one function virtualized by a different virtual machine setting. The different virtual machines used are: - FISH32 Black - TIGER32 Black - PUMA32 Black - SHARK32 Black The virtualized functions are very short, approximately 20 asm instructions. No other protections are used. The virtualized function will execute when F1 is pressed. codevirtualizer_2.0.8.0_demo_devirtualizeme.rar
