Here are the pinouts for the headers on the Arpicade 3/4 player adapter pcb -

Please note, the K Headers for 3 & 4 players (K is silkscreened on the adapter) should be used if you have a standard Konami Cabinet. The M Headers (Midway) are used for cabinets like NBA Jam.

The Konami style 3&4 player pinout of the board is as follows -

• 1 Coin
• 2 B6
• 3 Left
• 4 Right
• 5 Up
• 6 Down
• 7 B1
• 8 B2
• 9 B3
• 10 Start
• 11 NC
• 12 B4
• 13 B5
• 14 NC
• 15 GND

6  START
7  UP
8  DN
9  LT
10  RT

With the 4 player adapter, it is important to line up the pins properly when inserting into the main jamma adapter. Properly fitted, the outer edges of each PCB will line up if looking overhead. See pic below -

There are issues if you misalign. ie no power. the JAMMA adapter fuse will blow if this happens to save the board. But, agaim, no power will get through the JAMMA adapter to the Pi.

Other items could be bad SD card or a dead Raspberry Pi. Or, you may have an issue with your game cabinet wiring/power supply.
