Personally I prefer $0000 at the bottom and $ffff at the top. Higher addresses are higher in the diagram. Like in a coordinate system you start with 0 at the bottom. Just seems more intuitive to me.

Like how the screen and colour memory is laid out, lowest value - top left, highest value - bottom right.

Still, neither format is wrong, just personal preference.

Love & Peace :)

$FFFF at the top is definitely wrong.

1. You don't put numbered lists, like this one, in descending order

2. Look-up tables are conventionally low-to-high

3. 6502 is little-endian anyway :wink:

With apologies to those who think $ffff should be at the bottom, it is more common for 0 to be at the bottom and $MAX to be at the top:

THat said, it's obviously not unheard of to put them the other way. I think most of the periodicals of the day in this space, though, did 0 at bottom. Mapping the 64, for example, and the Project 64 memory map, among others.

Put it in a landscape so it cross two pages (rotate it 90 degrees), start with $000 on the left and $ffff far right?
