fast forward to the good part...

while the example is a cable box, this what is done to literally read the bits off a rom and other chips... and to examine the logic in the chip... notice the 6502 in here! That darn cpu keeps going and going and going.... :)

 

Dead roms are normally not dead inside or have minimal errors, most dead roms are dead at the bonding wires or have microsopic shorts that do not effect the bit patterns, you recover the data no problem.... yeah this is my idea of fun...

 

yep frying is in here too! controlled frying to glitch the acp... :)

 

he goes on to load code to the ram and have the 6502 process it....
