Hey guys, Although not much of a poster I am on here most days and am amazed by the dedication and knowledge of retro arcaders...
I recently picked up an upright GTi Club for my young son which was working perfectly, I came to it last week and all I now get is a bad rom 25V on the boot up screen and then it restarts, just going through a loop.
I have noticed 2 wires have come away from the Jamma connector (which looks a bit weak ) I am going to fit a new connector and rewire it to eliminate that issue.
Its not the easiest machine to work on and although is Jamma the video connectors go to a separate part of the PCB so I can't really send it to my friend Irongiant.
Can any please help me out or point me in the right direction here? The only error on the boot up is the 25V do I need that actual rom replacing.
Thanks Mike

For a start, I'd try reseating all the ROMs (all socketed IC actually), it could just be a little dirt in a socket.

I loved GTI club....one of the "last" games I played in the "arcades"....love the shortcuts and for home use the "bomb" mode is fun too ! Can't help you much though...

Thanks for that, I haven't removed the board yet I will have a go when I'm back home

I have checked all the chips that are socketed are ok and totally reworked the Jamma connection as that was a bit loose in places but still got the 25V rom error... Do ya know any one that might be able to burn a new rom and fit it for a reasonable price? Thanks I'll post the question if need be. Mike
