| Zaphod 13. Dec 2006 | geeko, I have patched the hidden exe, "G1xn", so that I can play the game without the nag screen, but I don't know how you extract G1xn from the jpg. How about a hint...? |

| geeko Author 16. Dec 2006 | How many kinds of patches did u apply? Does g1xn work as a standalone executable without nag? hint: U can add data at the end of a JPG without affecting the display of the picture. |
| Zaphod 17. Dec 2006 | I patched out one of the "WinExec"s so that WordPad is not started. That was the easy part. Then I redirected the program at one point to my own very small piece of code which made the program ignore the WM_EXIT message that otherwise stops it. But where this exit message comes from I can't figure out...this is why I can't write a tutorial, I simply don't understand the crackme well enough. |
| Zaphod 17. Dec 2006 | Yes, G1xn works as a standalone without the nag... |
| geeko Author 18. Dec 2006 | if u trapped WM_EXIT. can u still exit the app in the normal way? if not, then your solution is not good. U should do more patches |
| Zaphod 18. Dec 2006 | Yes, I can exit the normal way. The code I inserted makes the program ignore the first WM_EXIT, but not the following. |
| Zaphod 18. Dec 2006 | By the way, my best score in the game is 157 :) |

| Zaphod 19. Dec 2006 | No, it doesn't, but I believe you :) |
| geeko Author 19. Dec 2006 | so write tutorial, send the patched program |
| Zaphod 20. Dec 2006 | geeko, what I can write about this crackme is simply not good enough for a tutorial, but I'll send a private message to show you what I patched. I hope someone writes a proper solution... |

| DeepBlue 24. Dec 2006 | Are you serious? :O No cheating? |
