I know this is not strictly to do with games but it is related. I've been experimenting with a Sandbox system, it works great by hooking the windows API and intercepting NtWriteFile requests for the Sandboxed app. Now I would like to implement this as a function of igLoader but I'm also aware that API hooking widely used by spyware type apps. So you think this would bring a tonne of crap and should I just forget this idea alltogether? THanks Tim.
