There are different types of ROMs that can be used, but standard 2716s
and 2732s will work. (Some of the masked ROMs had their select lines
inverted which meant ROMs at the same address as their 27xx EPROM
counterparts, had to be plugged into different sockets, but nothing on
the board changed. -- This is mostly a problem when trying to dump the
ROMs using an EPROM burner.)

Star Castle and Armor Attack are both only two intensity level games.

The only multi-intensity, B&W, games were Solar Quest at 64 levels,
and Sundance at 16 levels.
