I am not an expert... but I "think" I did figure this one out.
Typically, if you don't see the inputs for a game in the main driver, they will be in a separate linked file... in this particular case:
Line 14: #include "includes/konamipt.h"
After reading the file, it looks like many Konami games are going to link back here for reference (e.g. Finalizer).
Your last lines below list the inputs you're worried about:
> PORT_START("P1") > KONAMI8_B12_COIN_START(1) > > PORT_START("P2") > KONAMI8_B12_COIN_START(2)
Go back to konamipt.h and search for each line, and you'll find:
#define KONAMI8_B12_COIN_START( player ) \ PORT_BIT( 0x01, IP_ACTIVE_LOW, IPT_JOYSTICK_LEFT ) PORT_8WAY PORT_PLAYER(player) \ PORT_BIT( 0x02, IP_ACTIVE_LOW, IPT_JOYSTICK_RIGHT ) PORT_8WAY PORT_PLAYER(player) \ PORT_BIT( 0x04, IP_ACTIVE_LOW, IPT_JOYSTICK_UP ) PORT_8WAY PORT_PLAYER(player) \ PORT_BIT( 0x08, IP_ACTIVE_LOW, IPT_JOYSTICK_DOWN ) PORT_8WAY PORT_PLAYER(player) \ PORT_BIT( 0x10, IP_ACTIVE_LOW, IPT_BUTTON1 ) PORT_PLAYER(player) \ PORT_BIT( 0x20, IP_ACTIVE_LOW, IPT_BUTTON2 ) PORT_PLAYER(player) \ PORT_BIT( 0x40, IP_ACTIVE_LOW, IPT_COIN##player ) \ PORT_BIT( 0x80, IP_ACTIVE_LOW, IPT_START##player )
Your inputtags are P1 and P2; your inputmasks are listed above... that "should" work, if I'm reading this right. (I don't have ability to test right now).

RELAX and just have fun. Remember, it's all about the games.
