Thank you both for the advice, I will definitely turn off both of those settings. I will probably use Nestopia over FCEUX because I know lots of top runners use it and prefer it over others.

Are there any rules forcing certain emulator settings to be used? On top of that, are there any recommended emulator settings to use? I'm using Nestopia 1.40.

Thanks

Alright thank you for the help I really appreciate it.

Thanks for the responses - In the .bat file I use it injects / tries to inject rinput voidedifbroken. Sorry if I didn't make it clear MagicSalad i'm trying to enable, not disable raw input. I load the portal.bat file which includes at the end - "RInput\RInput.exe" hl2.exe - however when Portal loads if I go into the mouse options there is no setting for raw input. The command m_rawinput if I enter it into the console also responds with Unknown command "m_rawinput."

Thanks

Is there no raw input in the Source Unpack 2.4 version of the game? Thanks
