romload.cpp: reduce copy-pasta (nw)
(nw) I fixed the errors found by adding validation to software list data areas.
Most of them seem to be simple copy-paste errors hidden by the fact that the
default device_image_interface loader ignores the data area size (as opposed to
the "ROM" loader). There was one C64 cartridge with a missing zero on the data
area size that was pretty clearly wrong.
Get rid of a couple of copies of the CC0 text. Add header comment to
CC0 files to remind people editing them what the terms are. Also add
some missing XML headers. The header comments in layouts won't bloat
the binary - they get stripped out before compressing, same as any other
comments.
cartridges and implemented the IntelliVoice expansion and
the Entertainment Computer System expansion as passthru
devices. The official syntax to launch games requiring the
speech expansion is now
mess intv -cart voice -cart2 gamename
which corresponds to mounting the IntelliVoice and plugging
the game cart in its subslot. The official syntax to launch games
requiring the ECS expansion is now instead
mess intv -cart ecs -cart2 gamename
and
mess intv -cart ecs -cart2 voice -cart3 gamename
if the game requires both expansions at once. For additional user
friendliness, we also offer intvecs (which emulates an Intellivision
unit with both expansions added) and intvoice (which emulates
an Intellivision with Intellivoice expansion added) drivers, where
games can simply be mounted with the -cart media switch. [Fabio
