Strange format... First 5120 bytes looks like program code but is the same code for every archive. Data itself might not be protected but index data, including offsets are. game engine might have anti-debugger functions. Something to do with exceptions. Passing the ones that come up to the application rather than the debugger seems to solve the issue for now.
