Trouble with hide advance option

a screen shot, version of the emulator and plugins and system spec would help... I don't quite get what you are saying..

I am assuming you are using PJ64
But have you tried Options-configure graphics plugin and untick "hide advanced settings"?

darkman in project 64 go Options->Settings..->Options and then untick "Hide Advanced Settings". Then close the Settings dialog and go Options->Settings again and all the advanced should be there..

or for graphics go Options->Configure graphics plugin... and then untick the "Hide Avanced Settings" tickbox...

another reason might be that you have restricted access to the registry on your pc and pj64 cant modify the registry, in that case there isnt a lot u can do except get Administrator access.. but i doubt it, so ignore that last bit
