I may have to mail him, eh?

	Actually, Quor is on this list, or at least the address from which
he used to post is still on the list. It's been awhile since we heard from
him.

	Regarding your question about why there's all that C-ASM linkage
written in ASM...umm, well good question...:) The best answer I have right
now is, "That's the way Quor did it originally." Fortunately, I see that
Jim has posted a more technical answer.

	I've attached said cheesy ROM as well as the main source code for
it. The ROM simply tiles the screen with a simple pattern (like all one
letter) and allows you to scroll around. There are also some simple
sprites in the upper left corner. Use the '-m' option in TuxNES to play
with the mirroring. I wrote this ROM to help me understand mirroring. The
patterns should change depending on which mirroring you choose.
