Pure luck on that one.  Was a guess, shooting from the hip.

What intrigues me is what the cause of the problem was/is.  I'm guessing its not a hardware problem (ie coils / switches) but perhaps a logic issue or software problem on the CPU.  I've never seen this before...What version of ROM is in it Damien / Mitch?

JohnWart Jr is the master when it comes to ROM's...I would assume Mark.c. put new batteries in it for you, so the audits etc would have been reset at least when it landed from Italy to Melbourne.

If it had 4 years worth of audit history I could imagine the memory filling up, but it should have no bearing on gameplay...  Very interesting indeed...
