I mentioned it over on your cursors' thread, but the short version is that GIMP will load it as a raw image file. (each four byte group is R,G,B and Alpha for a pixel in order)
<edit>
The process formerly outlined here was stupidly baroque and I feel ashamed. The only excuse I can offer is that I was solving each problem as it arose without giving sufficient thought to the overall objective. Coming soon: a sensible, practical approach.

OK, first step is to have your cursors ready. You will need all 8 cursors, with the alpha included. You will need two files, one of 16x16 cursors, one of 48x48 cursors. The cursors should be in order from top to bottom (as in the op post, except with real alpha).
Save each of the files as a raw image (you need to manually select the file type), with the default settings (Standard RGB)
Concatenate the 48x48 file to the end of the 16x16 file.
Code: Select all
copy /B cursors16.bin+cursors48.bin cursors.bin
