2 Weird Wires under my MV1-FZ1S

[kahel]

I bought a MV1-FZS and there are 2 wires running under it from the bios to the secondary board connections. When i received the board the BIOS was not a authentic BIOS , it was a programmed eprom with a window and a sticker written SF2 on it . So i am wondering if the wires are for some kind of hack or to make this fake BIOS work . I replaced the fake BIOS with a Unibios and it works but i was wondering if i still need those 2 wires.

Any of the pro know what those wires are for ?

here an image of the underside.

I think those pins are GND and VCC. So this maybe a repair and they just choose to tap power and ground from the BIOS EPROM.

Thanks for the info! I'll check it out with my multimeter.

Man that board looks terrible Hopefully you didn't pay much for it.

Looks like two data lines.

Nope i didn't pay much for it but it works well especially with a unibios. So i cut the wires to see what would happen and i wanted to replace them anyway. So without the wires i get a cross hatch instead of the game. I soldered some 24awg wires and it works perfectly again. Feel more solid also.
