I installed ZC on linux yesterday and I have a few questions.

When I installed it, it didn't ask me for my admin password, and it has always asked me for that when I installed programs in the past, I was wondering why that was. (I am still learning about linux and am curious about things like this)

When I run it in 320x240 (windowed or fullscreen) it runs full speed, but when I set the resolution higher it goes around maybe half speed, is there a way to make it run faster? Or is my computer just too old. Also when I run it in 320x240 fullscreen it is small and has a big black border, anyway to make it run without the border at full speed?

Also the download link for this at zeldaclassic.com wasn't working, I downloaded it at purezc.
