Half Life erkennt nach erneuter Installation die CD nicht mehr!

(Anonym) / 2 Antworten / Baumansicht Nickles

Ich habe vor kurzem mein Half Life deinstalliert, da ich mir eine 1:1 Kopie davon angelegt habe und testen wollte ob alles funktioniert (Installtion, usw.). Nach der Installation, die reibungslos verlief, wollte ich den Storymodus starten und dann kam die Meldung, daß ich die Half Life CD einlegen sollte. Nachdem er auch nicht die
Original-CD erkannte, auch nach einer Neuinstallation mit dieser nicht, gab ich einem Freund die Kopie und siehe da es funktioniert bei ihm ohne Probleme.
Wäre toll wenn mir jemand bei meinem Problem helfen könnte! ((Anonym))

hi, (very) quick guide to cracking HalfLife v1.0.0.6
need w32dasm8.9(3) & hex editor
run the game without CD, click game/new/easy. it asks for the CD 3 times then says failed authentication.
load hl.exe into wdasm32. no win95 dialog box to ask for the CD, so we check functions/imports
for GetDriveTypeA, double click it and up pops this little snippet...

right then, the code that calles this bit checks eax, jne to play the game, so we make it return
not equal all the time. (or patch the code that checks the return value, but thats boring...)
:0041EE54 750D jne 0041EE63 :0041EE56 33C0 xor eax, eax patch offset 1E254 in hl.exe, change the 750D33C0 to 33C04090
or be boring and patch
