[game_preservation] Congratulations to Jon-Paul Dyson and Greg James!!

Hi Devin,

If Greg James is Dr Decapitator then he likes to keep his location and
identity secret.
Dr Decapitator has access to a scanning electron microscope at his place of
work.
I thought this might have been a university and have something to do
with the academics at IGDA.


I first heard about this de-capping method from one on my customers at my
newsagency.
He had developed security protocols for cashless ticketing systems, and was
working on a cashless purse system for small transactions using mobile
phones.
He knew of this method of using a scanning electron miroscope from his
miiltary- intellegence - security background and I believe was using this
method
of decrytion to gain knowledge of the inner workings of mobile phones
for developing security protocols with his work.

He was into retro games and suggested using this method for decrypting
information from security chips on arcade boards.
I put him in touch with the Guru, and this knowledge was how the decapping
project came into being.

In answering your question from what I know arcade board schematics
are useful when threading the hardware components as software.

The person that is emulating and decifering schematics on non rom games pre
1975  is Gregf on the Mame World forums.

I don't have an email address for him.

I'm sure any blueprints and schematics of arcade PCB's are useful to the
mame team.
I contact the Guru at

theguru_999 at hotmail.com

Regards,

Ting.
