Driver by Takahiro Nogi (nogi@kt.rim.or.jp) 1999/11/05 - Additional tweaking 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 "includes/magmax.h"
