Schmeizr uses a feature of this chip that other games don't seem to exploit. There
appear to be two banks of data ports (referred to here as front and back buffers).
These banks are switched when certain addresses are read - also very good protection
against trojans as it is non-obvious when data ports are switched.
It appears to work as follows.. When the front buffer is active (the state upon
reset) any writes to data ports push the existing front buffer word into the back
buffer (ie, a FIFO latch type of system). When the back buffer is active, any writes
to data ports affect the back buffer only - the front buffer data is not affected, and
there is no FIFO action.
By default the read ports return a scrambled address and scrambled data from a
front buffer port. When the back buffer is active most read ports return scrambled
data from the back buffer, however some ports work exclusively on front buffer data
even if the back buffer is selected.
There doesn't appear to be any way to detect what bank is currently selected - it
seems game code must maintain this state (if it matters).
