| boonz 11. Aug 2007 | bin runnin' olly's arse off to get gold. thanks for the tip! :-) |
| kch0pa Author 12. Aug 2007 | coding a keygen should be pretty easy if you know basic crypto, emulating the server shoudn't be much of a trouble too, but for sure, harder than coding a keygen. |
| kch0pa Author 15. Aug 2007 | Congratulations TiGa and boonz, how was it? :) |
| TiGa 15. Aug 2007 | If the server did more complex operations, it would have been impossible to solve without disassembling it. |
| boonz 15. Aug 2007 | I agree with TiGa. Personally I liked it: A quite refreshing change from the usual name/serial-keygenning. Keep 'em coming! |
| kch0pa Author 15. Aug 2007 | Standby for #2 :) |
