-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.
