Rom Versions
------------

Darius appears to be a revision of Dariusj (as well as being
for a different sales area). It has continue facilities, missing
in Dariusj, and extra sprites which are used when continuing.
It also has 2 extra program roms.


Use of PC080SN
--------------

This game uses 3 x PC080SN for generating tilemaps. They must be
mapped somehow to a single memory block and set of scroll registers.
There is an additional text tilemap on top of this, to allow for
both background planes scrolling. This need is presumably what led
to the TC0100SCN tilemap chip, debuted in Ninja Warriors (c)1987.
(The TC0100SCN includes a separate text layer.)


ADPCM Z80
---------

This writes the rom area whenever an interrupt occurs. It has no ram
therefore no stack to store registers or return addresses: so the
standard Z80 writes to the stack become irrelevant.

When you add a coin there is temporary volume distortion of other
