To ferrari,
If you're still interested in inlinepatching of Aspack 2.12, take a look at the attached file. It's gdbnt from runtime.org. I have made an inline patch just to show how it can be done.( I made a patch that patches 3 bytes in the unpacked file. Don't pay too much attention to the patched program itself, it may not be properly cracked.). Just open the file in Olly and put a bpx at 0066B573. This is right after the xor-based decryption is done. Just singlestep from there and see what happens and where..
