dgen_tobin — Convert SMD-format Genesis/Megadrive image to raw (BIN)
dgen_tobin FROMSMD TOBIN
The ROM image FROMSMD is converted into a raw image, as seen by the
Genesis/MegaDrive console itself. The raw image is written into TOBIN.
Technically, FROMSMD does not have to be an SMD file; it can be any
format dgen(1) can comprehend, such as an image compressed with gzip(1),
zip(1), or bzip2(1).
