swizzle is a utility for reordering (swizzling) the address and/or data bits of a ROM image.
Usage: swizzle [options] in_path out_path
Supported options:
-h/--help- show this information and exit-a/--addr <bits>- specify address bit order (optional)-d/--data <bits>- specify data bit order (optional)-w/--word <num>- specify number of bytes per word (default 1, max 4)-b/--big- use big-endian byte ordering
<bits> is a comma-separated list of 0-based bit indexes (comma separated, most significant first).
Example: to reverse the order of bits in each byte:
swizzle -d0,1,2,3,4,5,6,7 in.bin out.bin
