Making my own fixed .exe?

[cdkiller]

check the sticky 'Guide's, Tutorial's & Hint's' thread here

gothic german version is SecuROM 4.84 + Armadillo wrapped + CD-Checks,
gothic english version is SecuROM 4.84 + SVKP 1.3x wrapped + CD-Checks

So what tool do I use

there r no public tools available. i think u never cracked a game before. u will prolly fail because u can´t go straight to SecuROM or other commercial protections without any knowledge.
