arrangement of pattern tables and name tables for background

[GradualGames]

It seems to me that for any one background, there must be hundreds of ways to represent it in memory since you could have the same patterns in any order so long as the name table points to the correct ones to form the final picture.

So my question is---are there good and bad ways to arrange the pattern table and name table, or does any arbitrary order produce the same performance from the PPU?

It absolutly does not matter. The PPU renders all tiles at the same speed, so you can arrange them any way you want.

Using consecutive tile numbers may help if you want to use increment instructions instead of lookup tables.

Also, having a text font in ASCII order makes conversion to and from ascii easier. Doesn't have to match the character numbers, just need to add or subtract to get ascii.

If you're using a board with a relatively powerful mapper chip (i.e. not discrete or MMC1) and CHR ROM, you can switch banks of 64 or 128 tiles at a time, so you'll need to arrange things in CHR ROM so that you don't need tiles from a lot of different banks at once.
