Help needed to hack an old DOS game
Hello, how are you?.
Recently I began a project to hack an old DOS game: Vanguard Ace. I have the full version since several years.
Problem is that the exe is packed with the WDOSX extender packer, so I can't hack the exe.
I tried to use a free app avalaible at sourceforge:
https://sourceforge.net/projects/wdosxunp/
The app shows lots of info about my exe, but crashes before it can unpack it.
It crashes with a 0xC0000005 exception which means illegal memory access.
I took a look at the program source code (its very little code, the compiled app its just 4kb), but couldn't guess what's wrong with it.
I was hoping someone more experienced than me in C++ developing could take a look at the sources and fix the illegal instruction issue that the app has now.
I attach a 7z with the WDOSXUNP app, that also includes the source code and a copy of the EXE I'm trying to unpack.
Any help will be greatly appreciated.
Regards and thanks
