note, there's a Dallas DS5003FP and battery on there too, which I can only assume is somehow related to the DS5002FP suicide chip you find on Gaelco boards etc. I can also only assume the code is/was in the SRAM, and is probably long dead. If the battery voltage is >2.8 (and at no time has anybody removed the battery or accidentally triggered the suicide mechanism, which can happen if you so much as look at it funny) then the sram might in theory still contain the code, and the dallas might in theory still contain the key for it, but if it's been sat disused for so long, in unknown conditions, that's kinda unlikely.

Morten personally outside of contact on IRC and emails, he was a key part of the team of two man Danish team featuring Peter Wilhelmsen who together overcame some of the toughest challenges emulation faced in the time they worked together....The DS5002FP protected Gaelco games for example could only be dumped thanks to the work he put in, a path full of setbacks, boards suiciding and even once a working setup was found there was still a high risk each time. To put things into perspective, prior to Morten and Peter taking on the challenge it was one that most people had already written off as simply impossible.

I thought Peter was also able to do this type of work, but if not without Morten's involvement, that blows. Gaelco game fans lucked out and then some.
