Stephh's notes (based on the game M68000 code and some tests) :
- Player 1 Button 2 shall not exist per se, but pressing it speeds the game.
That's why I mapped it to a different key (F1) to avoid confusion.
It appears (as well as Player 2 Button 2) in the schematics though.
However I don't see it in the wiring connector page.
- DSW2 bit 8 is not referenced in the US manual and only has an effect
if you have EXACTLY 10 credits after you pressed any START button
(which means that you need to have 11 credits if you choose a 1 player game
or 12 credits if you choose a 2 players game).
When activated, you are giving infinite lives (in fact 0x60 = 60 lives)
for both players, you can still lose parts of the ship but not the main ship.
See code at 0x0001e6 (ships given at start) and 0x0044e6 (other stuff).

/*There are three AY8910 chips and four(!) separate amplifiers on the board
* Each of AY channels is hardware mapped in following way:
* amplifier 0 gain x 1.00 <- AY0 CHA
* amplifier 1 gain x 1.00 <- AY0 CHB + AY0 CHC + AY1 CHA + AY1 CHB
* amplifier 2 gain x 4.54 (150K/33K) <- AY1 CHC + AY2 CHA
* amplifier 3 gain x 4.54 (150K/33K) <- AY2 CHB + AY2 CHC
*
* Each of the amps has its own analog circuit:
* amp0, amp1 and amp2 are different from each other; amp3 is the same as amp2
*
* Outputs of those amps are inputs to post amps, each having own circuit
* that is partially controlled by AY #0 port A.
* PORT A BIT 0 - control postamp 0 (gain x10.0 | gain x 5.00)
* PORT A BIT 1 - control postamp 1 (gain x4.54 | gain x 2.27)
* PORT A BIT 2 - control postamp 2 (gain x1.00 | gain x 0.50)
* PORT A BIT 3 - control postamp 3 (gain x1.00 | gain x 0.50)
*
* The "control" means assert/clear input pins on chip called 4066 (it is analog switch)
* which results in volume gain (exactly 2 times).
* I use set_output_gain() to emulate the effect.
gain summary:
port A control ON OFF
amp0 = *1*10.0=10.0 *1*5.0 = 5.0
amp1 = *1*4.54=4.54 *1*2.27 = 2.27
