| br0ken Author 28. Mar 2008 | I'm glad you guys liked my cme. I'm gussing this is the only lvl 2 cme (so far) with the shortest algo! hehe :D Ox87k, I had to delete your comment, i'm sorry :) Please don't post valid serials here, it kinda ruins the fun. I hope you understand ;) |
| br0ken Author 29. Mar 2008 | Dude, no posting valid serial even if its related to your name :P Comment deleted, sorry! :) |
| ksnrcp 31. Mar 2008 | huhu very good man ,i will learn it more in last serial algo made me very headache : ) cause im newbie next time i must win it ,hehehe |
| ejube 04. Apr 2008 | bloody quadratic equations :) |
| aout 07. Apr 2008 | Finding a valid serial and understanding the algo - done, turning the algo into a keygen - FAIL. Might work on that and will post a solution then maybe. |
| br0ken Author 19. May 2008 | Nice tutorial. Everything is explained. I couldn't ask for more :) Well done Kofiv! |
| costy 19. May 2008 | what does "SAR EDX,2" do?? |
| Zaphod 19. May 2008 | SAR = Shift Arithmetic Right SAR EDX,2 divides edx with 4. Like SHR, but the carry flag receives the last bit shifted out. Download "opcodes.hlp" ( shouldn't be too hard to find ). |
| kofiv 19. May 2008 | Thanks. I really enjoyed working on this one. |
| costy 19. May 2008 | thank you Zaphod |
