in case you dont know how to do it in OllyDbg, after changing the jz to jnz, look for 'save changes to executable' from right-click menu

Make sure you're using the correct opcode. You will end up with an invalid image if you use an opcode of different length. There are a few utilities around, but i use this one for the most part currently. Hope it helps.

usually, OllyDbg's built-in utility to 'code' while debugging works so no need for manually changing opcodes.

You gave me a idea to write a generic file patcher to patch files based on the offset got in w32dasm.
Soon I'll upload in my home page when it's completed. For screenshot see: http://board.flatassembler.net/topic.php?t=6179 If you want an alpha version send me a PM. |
