April 22, 200916 yr Hi diablo, A really funny keygenme, wasn't too hard though. I like the problem behind it. But sadly it has a mayor flaw in it (I assume you didn't want that.) 004012FB |. 57 |PUSH EDI 004012FC |. E8 47350000 |CALL d2k2_crk.00404848 00401301 |.

April 22, 200916 yr Author Hi diablo,A really funny keygenme, wasn't too hard though. I like the problem behind it. But sadly it has a mayor flaw in it (I assume you didn't want that.) 004012FB |. 57 |PUSH EDI 004012FC |. E8 47350000 |CALL d2k2_crk.00404848 00401301 |.

April 22, 200916 yr Okay seems it wasn't clear to you what I meant with the flaw, This keygen "exploits" this flaw, without paying attention to any matrix.Cheersd2k2_10_keygen_flaw.rar
