Hi !
Dyn!io... I'm neither so kind... nor trying to increment my post counter. I just try to be polite and thank people who are kind enough to reply my answers (just like you in fact... ). If moderator finds this reply not interresting at all, he (she ?) could just reset my post counter : I'm not gonna jump through the window for that.

So, apparently, S.F. reminds me an old protection scheme from the apple II scene called MCODE. It was a sort of interpreted language used to fool crackers. This scheme was present with Electr0nic Arts games in the early 80's. It was a simple version of P-Code from UCSD Pascal (1979) (using 8 registers, dozens of opcodes ....).
The goal was creating an unknown language to turn the protection routine into a sort of maze inpossible to trace by crackers. A kind of virtual machine in fact, where executed code is unreadable.
Considering the fact I'm not a 'Crackhoolic' psycho, I'll follow your advise and try to look at Xprotector first.
I can code my own tools, but for me it's just a hobby, I've also got a social life, and I'm of course *not* a cracking god, I'm just curious about this 'nightmare' called 'StarF0rce'.
Even if the goal is too far away for me to reach, I'm still being curious about it.

So, once again, thanx all !
bye bye.
