please try it.. my friend sent it to me but i can't solve it Yt__o_KeygenMe2.zip

I worked on a target with this algo when a little after I started reversing. It gave me a hard time fishing a serial so I just patched it and went about my way. I have this thing of going back to old targets and finding new solutions. Anyway recently keygenning has peaked my interests so I brought out PROGRAMX to see if I could keygen it. I couldnt belive how simple it was. It was right there smacking me in the face, anyway thought it would be a good exercise.. So I ripped the algo and modified a couple things and I leave you with this. No Anti, no other b/s just straight code. DrPepUr_6.rar Dustyh1981

hello... non-ripped valid keygen with source is the golden solution.. http://www.mediafire.com/?vrfj9x1zsyc

This is my first attempt at a KeyGenMe app . I wrote an mp3 player app. purely for programming practice so do not expect state of the art graphics or playback. The app as presented is an 'unregistered' version which a correct serial will convert to the 'registered' state. Please note that the app. will not run directly but must be executed via a shortcut. When you solve it please write a tutorial as some parts of the solution may answer at least one question I have seen posted on the forum. I wrote the whole thing in assembly language in Windows XP SP2, and it will not work on non NT based systems. Happy reversing in whatever you are working on Cheers InsaneFIDO FID…
