SCF CrackMe 6 - Back To The Old School
« on: September 16, 2007, 07:43:41 PM »
Toto CrackMe je ako spomienka na stare casy. Urcite si vacsina pamata na DOS  (to su tie skarede cierne okna ak niekto neviete co to je :-)

Cielom je najist spravne registracne data.  

Pravidla :
- Kedze patch by bol velmi easy (1 bajt) akceptuje sa len spravna registracia ako riesenie.

PS: V dnesnych mega, giga casosch ma cme iba 5742 bajtov takze aby ste to nevyriesili ? ;-)

Hm, v com to dubugujete? Alebo mi na to postaci len stary dobry disassembler w32dasm?

BTW: 2DARKER: Dal si toto cme aj na nejake ine fora(weby)?
BTW2: 2DARKER: Ked si mi pisal, ze robis nejake oldschool cme tak som vobec netusil, ze to bude 16bit dosove cme - fakt brutal  :eek: . A ten oldschool bude fakt asi oldschool lebo ja som s RE zacinal okolo roku 2000 a v tej dobe take 16bitove veci uz neboli(teda si aspom nepamatam :rolleyes: ).

- je to iba na tomto fore, ste privilegovani ;)
- tak kuva aby ste mali zabavu :)  klasickych cme mate na nete kopec, xce to zmenu -> aspon sa naucite nove veci, "Cracking Hrou"  ;)
- na debug existuje viac alternativ ....

k nesrovnalostem dochazelo vzdycky na entry pointu. zajimavym pristupem muze byt taky zkompilovani funkci pro praci s retezci v pascalu a pak porovnat asm kod.
