 R> i really like to watch videos of Robin @ 8-bit show and 
 R> tell, who cracks and disassembles commodore vic20/64 
 R> software and explains what's happening.
 R> altough i've never tried.

I haven't watched 8-Bit Show and Tell before, looks like a great youtube channel!

Recently I came across solutions to the +HCU 1999 Strainer - a set of challenges from the 'cracking university' +HCU - it's great information.  Several writeups from different people working through a few challenges.  These writeups are an amazing source of information about how to reverse engineer DOS software.

I was looking for a working crack for Terminate 5.0, which led me to the +HCU strainer solutions - it turns out that cracking Terminate was one of the challenges!  Spath's solution included assembly source, so I built that and have a working crack.  More fun than just downloading a .exe, way easier than doing the reverse engineering work! :)

The comments and solutions from each of the participants are full of detailed technical information and techniques.

 R> yeah you got some "colds and hots" in the DOORGAMES ;)

Yeah... yeah.
