Someone with 2-1 multijamma board ??? i need help,doesnt switch between PCBs board...

Hi, i recently buy a multi jamma board 2 in 1,i plug two Pcb´s,neo geo and a pandora box 3 but the remote control doesnt work,doesnt switch between PCB boards...what is the problem ?? can someone tell me the installation or working of this board ?


Thnks !!

It's probably because the Pandora isn't JAMMA.

Sorry,I have already solved,easy,the 2 in 1 need +5v adapter not included in the pack.
