There is a simple way to do your own cracks , if the disc is protected with the "Safedisk no.1" protection routines ...
You can check with tools , or simple if you watch on the original disc .
When there is a file which is called "Clockspl.exe" , an "*.icd" and a file called "dxplayerdll.dll" ...
If this is given , simply download the tool "Unsafedisc 1.5.5" ...
After that , copy the following files from your copied (important : not from the original disc !) and updated disc to a temp directory and start "unsafedisk" ...
The files are :
*the main EXE file
*the ICD file named the same as the EXE file
*the dxplayerdll.dll file ...
In unsafedisk you now click on the ICD file in your temp directory and let "unsafedisk" do his work ..
After a "Success" message , you find a new EXE , called "Testme.exe" in the temp directory ..
Now change the name of "Testme.exe" to the name of the original exe and copy it over the installed one ...
So , now you have done your own crack with simple tools :-)
