    First of all, this isn't my crackme. This is Sharpe's from Crackmes.de. It took me a little while to solve it, and when I did, I was very pleased with the programming and programmer. It's a very good crackme! I warn you though, the difficulty is a little under-rated. Enjoy! -Cobrasniper555 eight.zip

    This is an attempt to code an "uncrackable" program in assembler. See http://www.tuts4you.com/forum/index.php?sh...c=12949&hl= to read the complete story. Aesthetics-only patching is NOT a valid solution! e.g. editing "UNREGISTERED" into whatever in a resources editor. Of course that this doesn't effectively register anything, right? Adding code, etc to make the ReverseMe display something isn't a valid thing either, right? You may however patch the reg scheme so that false data is still accepted as valid. If patching, please explain your solution so that I can verify its validity. It's clear that a keygen is preferred. Good luck and have fun lena151. ReverseMe_9_b…
