by Jarek Burczynski + + +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). + +***************************************************************************/ + +#include "emu.h" +#include "cpu/z80/z80.h" +#include
