Process

  I have recently noticed that the Opera browser, in the versions from 4.0 to 4.02, is present in different builds/compilations so a patch may not work even if the main version is the right one. � This is very stressful, and it would be ridiculous to publish five or six patch for the same program. In this situation the funny thing is that the protection is always the same even if it is located at different offsets in the exe file; so I decided to "explain" the routine giving you a chance to patch Opera by yourself. This is the piece of code that decides the rightness of your registration code:

 
:00410AF6 E890A20E00 call 004FAD8B
:00410AFB 84C0 test al, al
:00410AFD 59 pop ecx
:00410AFE 7502 jne 00410B02
:00410B00 C9 leave
:00410B01 C3 ret 
:00410B02 0CFF or al,FF
:00410B04 C9 leave
:00410B05 C3 ret 
 

                 if the serial is wrong (al != 00) al is set to FF with "or al, FF" Now, you have only to change this code and put 00 in al even if the serial is wrong. You can do it by replacing "or al, FF" with either a (and al, 00 opcode --> 24 00) or (mov al, 00 " " --> B0 00) Don't worry if you don't know assembly language; to patch Opera you'll need only to follow the following instruction... 

Instructions

1. First of all, you need a hex editor (WinHex, UltraEdit, so on..) that will let you search the protection routine opcodes. I think E890A20E0084C0597502 is quite long and will avoid multiple occurrences in the searching process. btw, be sure to get only one result! well, now locate OC FF and overwrite it with either 24 00 or B0 00, save the file (that you have previously backuped, right?), close all, run Opera and enter you name with a registration code (longer than 12 chars) of your choice. 

2. Enjoy!
