I finally got around to trying your suggested tileset approach, and I ran into a a couple roadblocks. Let me explain.

I'm taking a 132 char x 60 char canvas and dividing it into an 8x3 grid of frames. Each frame holds a 16 char x 16 char tile.

In my test code, I'm iterating over each frame and .load()ing my tileset. The tileset is 128x112. I have tried various versions of this tileset, as an ANSI file, a BIN file, with SAUCE or without. No matter what, I always run out of memory.

Additionally, when I try to debug the errors, Frame.js is giving the wrong data dimensions for my tileset files. As I said, the tileset is 128x112, but if I call .data_width and .data_height after .load()ing, I get 17x832 for the .ANS version or 129x112 for the BIN.

I don't *think* I'm asking too much of the system memory-wise, but maybe I'm wrong. If you have a minute could you take a look and tell me if you have any thoughts on the out-of-memory issue, or the wrong data dimensions?

My test code is here: https://gist.github.com/Kirkman/0853cad3deaad373f000#file-1tileset-test-js

The out-of-memory errors can be seen here (They are slightly different depending on whether you load the ANS or BIN version of the tileset):

The debugging info is here:

You can download the ANS and BIN version of the tileset here:
