+====== Bitmap to sprite converter written in Python ======
+This is a simple Python hack that converts monochrome images with a multiple of 24x21px to an array of sprites. It can save the sprites with or without load address. Public Domain.
+<code>
+#!/usr/bin/env python
+# .spr converter for arbitrary sized images (multiple of 24x21)
+# 1st argument: file to convert
+# 2nd argument: target file
+# 3rd argument: load address in hex (optional)
+# no error checking at all, I'm lazy :)
+import sys, struct
+from PIL import Image
+img = Image.open(sys.argv[1]).convert("1")
+if (img.size[0] % 24) != 0 or (img.size[1] % 21) != 0:
+    print "image size of %s isn't a multiple of 24x21!" % (str(img.size))
+    print "exiting!"
+    sys.exit(1)
+xoff = 0
+yoff = 0
+if len(sys.argv) > 3:
+    print "adding loader address"
+    sprbuf = struct.pack("<H", int(sys.argv[3], 16))
+else:
+    sprbuf = str()
+while yoff < img.size[1]:
+    while xoff < img.size[0]:
+        crop = (xoff, yoff, xoff+24, yoff+21)
+        print crop
+        cut = img.crop(crop)
+        cut_str = cut.tostring()
+        sprbuf = sprbuf + cut_str + struct.pack("x")
+        xoff = xoff + 24
+    yoff = yoff + 21
+    xoff = 0
+open(sys.argv[2], "w").write(sprbuf)
