Hi. I got a PE Packed binary [that have other binary and a DLL in it]. I need to patch some offsets of the DLL, but I can't actually unpack the file and/or change directly on the executable, or I get an error on the main proccess [it fail at checksum and quit immediatelly]. The workaround I made for this program is pathcing it directly at memory, after ran the main executable. I got the patch working, but I have to do it manually.

My question is: Can I make a custom "loader" to patch the binary at memory?

There's any tutorial/topic that can help me with this work?

Thanks to all =]
