Sorry for taking so long to reply.

About the MegaPlay, I already have a Megadrive/Genesis but thats not the point...
I would really love to get it working, it makes me mad when things stop working like this!

About the cabs, Im from Portugal, and here its hard enough getting Jamma boards, cabinets are even harder to find :(

Im running the boards through a supergun until I have the luck of finding a cabinet.

The Megaplay carts that I have are Tecmo World Cup, Sonic 2 and Golden Axe 2.

I have no idea about the Multi32 game, I havent tried it yet.
All the roms on the top PCB start with xPR-15xxx.
I guess tha code may correspond to the game title.

BTW, along with the bundle of PCB's I got I found a Gals Panic PCB! Seems to be dead also :( When I power it up only garbage appears on screen.
