Unprotect for URIDIUM (IBM PC)
BE SURE TO BACKUP YOUR URIDIUM DISK BEFORE STARTING AND USE THE
BACK UP FOR THE UNPROTECT.
Modify only the backup copy!!!
First you should rename the file or files
URIDIUM.EXE TO URIDIUM
Ex. C>rename uridium.exe uridium
Next Load program into debug...
Ex. C>debug uridium
Then Follow the sample debug session:
-s 0000 ffff b4 1c cd 21 : Search for first protection pattern
XXXX:YYYY : The search will return one address.
If more or less than one are returned
this unprotect may not work.
The value returned should be:
XXXX:7FF1 : If this is not the address returned
: then change the addresses in the patch
: file.
-s 0000 ffff e8 b2 02 : Search for second protection pattern
XXXX:YYYY : The search will return one address.
If more or less than one are returned
this unprotect may not work.
The value returned should be:
XXXX:81BF : If this is not the address returned
: then change the addresses in the patch
: file.
Now exit debug to apply patch:
-q <Enter>
Now apply the patch:
C>debug uridium <uridium.pat
Now it is time to rename uridium back to uridium.exe
C>ren uridium uridium.exe
The file DEMAB.COM must be copied into the same directory as URIDIUM.EXE
Now try to run the new (Hopefully) unprotected version of URIDIUM
C>uridium
