Output of SNES's map data for non-8x8 tile mode is incorrect #34

Although there's a relevant piece of code that handles this. It's never executed if map splitting is not specified. So, command arguments like -i <png> -W 16 -H 8 -B 4 -R -t <4bpp> -m <map> will result in an incorrect map data.

I believe I am having this issue as well, but enabling map splitting does not seem to help. Is there a fix?

I am trying to convert an image I tweaked specifically for 16x8 tiles for use with mode 5, and only part of the image is actually converted into tiles, making the final image on my SNES ROM look chopped up and screwed. Here is the image file I used, plus SuperFamiConv's output.

And here's the result as a ROM.
