The only thing that stands out in your syscheck is the lack of IOS58. It's hardly required, but it can come in handy for USB 2.0 support when HBC is installed on it. If you use the link in my sig for it, you can install the IOS slot, then reinstall HBC (from your existing HBC) and it will install on that slot.
The other thing, with Sniper Elite, have you set the game to "Force NTSC" in your game loader's options? That may be your problem. If that does not fix it, re rip the game from scratch.
