Comments

Cursor files consist of a file header (that is repeated several times), info headers, and cursor data. Cursor data contains an XOR mask bitmap and a monochrome AND mask bitmap. Whenever Windows draws a cursor, the AND bitmap is applied to whatever is on the screen. After that, the XOR bitmap is applied.

Files must be 255x255 pixels or less.
