use 716 files on mpu200 jumpered for 4x2716 (stock)
use 732 files on mpu200 jumpered for 2x2732
use 512 file for nvram.weebly.com board

Changes from stock roms:

1)
Left and right spinner counts will 'blit' to ball
in play display.  The left spinner has priority in
the case of both spinning at once.  The high spin
count is not saved in any way due to nvram memory
limitations.  The ball in play will return to the
display after a short interval.

2)
The extra ball blinking control normally switches
to a solid lamp on the next ball if not collected.

This now will blink on the next ball instead.

3)
The attract mode 7 digit countup has been sped up
slightly and the player score display will show
for a much longer period of time to make recording
of scores easier in a tournament situation.

4)
Tilting no longer removes earned extra balls.

5)
No more 'tilt test' in attract mode.  (Previously
tilt would 'work' during attract mode)

6)
Built-in switch test will display ALL closed
switches, not just the lowest numbered one, to assist
in finding switch matrix issues.  All closed switches
will show one at a time and each run through will end
with a zero flashing in the ball in play display to
indicate that the entire switch matrix has been scanned.

7)
On ball launch the drop banks are polled to see if
any targets are down and if none are, that drop reset
is skipped.


Changes related to DIP switches:

Background sound dip #8 changed to match manual.

Dip 8 on=background sound on
Dip 8 off=background sound off

Max credits always 99.  Dips 18 and 19 repurposed.

Dip 19 is now freeplay on/off.

Dip 18 now controls a temporary lighting of all
3 cards when you roll over the lane behind the GA
standup targets.  After a short time, the lit cards
will return to their previous state.


Dip 24, previously unused

On=Automatically change lit bingo cards per pattern
set by Dip 23 after a short time interval.  Change
cards on playfield will still change the cards.

Dips 25/26 for max lines function changed.

On 5 ball play, manual description matches mod, you can
select balls 2,3,4, or 5 for the 5k/line bonus.

On 3 ball play, set dips the same way as for 5 ball
but subtract one, so you can set 5k/line bonus
on balls 1, 2, or 3.  (i.e. set to '2' to get '1'
on 3 ball play)

Dips 15-16 HSTD credits now repurposed.

HSTD: 3 replays will be awarded if dip switch #6 is
set to ON.  (Replays awarded at score levels).  Dip 6
Off=novelty mode (HSTD still recorded, but no replays)

Dip 16 is now a bonus multiplier setting up to 5x.
Off=operate as stock, max bonus multiplier is 3x.

once and 3x criteria met.  Indicated by both 2x and
3x being lit.

Dip 15 is now a bonus removal setting.

On=Remove all bonus ball to ball
Off=Leave bonus ball to ball (stock)

Dip 14, previously unused
