[Coco] ROM -> BIN converter/loader

[Arthur Flexser]

What you suggest has been around many years!

After a while, some Rompack authors started protecting their programs from
this, so quite a few programs, particularly games, must first be
de-protected for this procedure to work.  The protection was usually some
code in the game that would switch to ROM mode (no effect if the game was
running in ROM as intended).  Or sometimes, the game would contain code
that would attempt to modify bytes within itself, (again, no effect if the
game was running in ROM).
