Rollercoaster

You know those tight little rollercoasters that surprise you when they make an incredibly sharp turn that you weren't expecting? I'm trying to follow the t7g exe file in OllyDbg, and it's a bit like that. I'm not really at the stage where it's useful, it's just for fun and to try out OllyDbg. Though hopefully it'll all soak in by diffusion as I stare at the screens of assembly language...
