I was in the computer electronics bussines 15 years ago and when I read this thread I remembered how I dumped a 'snapshot' of the SRAM in a small computer system when it was reading running a program I had to debug.
I basically put an identical memory chip and wired the address-,data bus and timing to the original memory, but the Vcc and gnd was connected to an external power supply.
Then I booted the computer and waited for the right time to power it off, and then the memory chip I had wired had a static 'snapshot' of the memory just before it was turned off. Now it was just a simple matter of dumping the RAM to a computer and save as a file.
Ok, that was 15 years ago on a simple 8 bit system, and I have no idea if this is even possible on ps3 memory chips. I haven't worked with hardware since but I just wanted to share this idea.
