All you have to do is make one huge bitmap of the levels, we have tools to split it into a map. F4 in MAME and lots of manual joining is all that's needed.

Why on earth do you need every possible indentation? You can surely rotate the pixel data yourself in code if you need 32 versions of it. The 68k has rotate operations after all.
