Anyway, I know there are a couple ways to do this, but I wan't to monitor the I\O pins on the ROM chip because I will eventually need to monitor the North-South bridge BUS, and I think that this would be a good way to prepare for that. Also I don't have a double-solder iron.
How would I get all these pins hooked up to my FPGA dev board? I was thinking I could get a very small conductive wire, and place it through the test-points which are on all the traces leaving the chip, and solder the fine wire to my larger-wire(which goes to the breadboard and eventually the one of the User FPGA I\O pins). How would I keep this neat and stop a short-circuit with such dense pins? Are there specialized wires for this or something? Will this disrupt the signal at all though provided I am just logging all the relevent pins on the ROM? And can I trust the XBox will access all of this memory? Because if it doesn't I won't get a full dump of the ROM chip.
