Minor update - got the app version running. I've supplied a screenshot, at 6MHz this time for some variety.
You mean like this?I don't think it looks all that much better, plus there's no speed increase whatsoever.
Yeah, it's not supposed to look better (as I said in my previous post, it will be of reduced quality). At any rate, are you sure you disabled everything, such as the grayscale interrupt (if you're using one) and your just doing straight one-layer black-and-white for the background with no overhead other than your tilemapper? For some reason I was thinking that you should at least get a minimal decrease in the number of milliseconds it takes to render. Even 1 to 2 milliseconds will increase the FPS by 1 in 6 MHz mode.

There's no fancy interrupts or anything.
