/* Semicom Baryon / Dream World hardware
Note: this hardware is a copy of Psikyo's 68020 based hardware,
the Strikers 1945 bootleg has the same unknown rom!
It isn't quite as flexible as the original Psikyo hardware
by the looks of it, there are various subtle changes to how
things work, for example the tilemap sizes and missing
transparent pen modification. This makes it rather hard to
merge with psikyo.c and it should probably be left separate.

Stephh's notes (based on the game M68EC020 code and some tests) :
- Don't trust the "test mode" as it displays Dip Switches infos
that are in fact unused by the game ! Leftover from another game ?

note:
Baryon has some annoying sound looping clicks / cutouts, these need to
be verified against the HW (it's a very cheap sound system, so it might
be accurate)
Baryon has playfield background which fade in with very rough / visible
edges. In this case the tilemap size registers from the original
psikyo hardware are set to be the alternate tilemap size, however that
doesn't make sense in the context of the data in RAM, which doesn't
appear to wrap properly anyway, again, it's likely this is just how the
game is. Furthermore the BG test in the test menu indicates that it
tests alternate tilemap sizes, but doesn't even write to the register,
probably a leftover from hardware development as the test menu is mostly
incomplete.
All: sprite priority, the original psikyo.c HW has sprite<->tilemap
priority but we don't support it here, does the clone HW support it?
All: sprite zooming, again the original psikyo.c HW supports this, but we
don't support it here. The Strikers 1945 bootleg in psikyo.c doesn't
appear to support it properly either, so it might be missing on these
clone boards.
