Uninitialized blocks often contains garbage, and emitting it on
the TRS-80 4P results in serious visual glitches.

Running a ROM on an everdrive is one thing, but running a ROM
directly is another: my hacked up sega.bin didn't have a proper

This new tool transforms a binary into a properly-headered ROM.

Has been tested on an actual SMS.

With this tool, we can send content to a TRS-80 directly to floppy.
This paves the way to writing ourselves a set of disks containing the
blkfs!

and remove cfspack, which will not ever be used again.

To update LATEST offset more easily. Will be useful for recipes.

Use it in shell instead of using popen()

In C this time. Python/Perl code is barely terser than C for these little
tools. Why bother with interpreted?
