crackme foarte usor: crcme.rar

[totti93]

Ai PM cu parola! Mi-a placut:D

[sulea]

deocamdata doar totti93 a gasit o rezolvare

[Flubber]

Ai PM.

Thanks 4 the challenge.

[sulea]

flubber a gasit si el solutia, felicitari

ma las batut (

Nu inteleg :

experimentul chimic

plec la scoala

L-am crackuit totusi sa se inregistreze la orice cod:))))

F6 E1 05 05 11 40 00 devine F6 E1 05 1E 11 40 00

solutia ta nu este valida, la fel ca altcineva de aici cauti doar sa afisezi mesajul cel bun.

daca se inlocuieste ce spui tu si introduci de exemplu serialul corect, vei primi o eroare 'din aia cu send / don't send a windowsului' (ca sa ma fac inteles)

dar probabil ca ai gresit la transcriere, iar in loc de 'add eax, offset loc_40111E' trebuia sa fie 'mov eax, offset loc_40111E'

deci F6 E1 05 1E 11 40 00 se transforma in F6 E1 B8 1E 11 40 00

NICI in acest caz nu este buna solutia deoarece se urmareste doar afisarea mesajului bun, programul ramanand NEINREGISTRAT

va voi face viata si mai usoara si va voi da codul sursa. daca nici de aici nu va faceti o idee, ...
