Modding a 64 chip is not hard, I did mine myself. This is what you have to do: Reconnect the blue wire back to the chip, see attached pic. This basically means you will not have to solder to the saturn chip at all (you can also not use the wire and simply brifge the 2 points on the chip). All you have to do now its to connect the red wire to the 5v powersupply (check in the saturn, there can be up to 4 places in a row you can put it in, but only 1 of them is the 5v), and you have to take the ribbon cable out of the place where it is now, insert it in the chip and the chip in the saturn where the ribbon cable was. The only annoying thing is that with 64 chip saturns the ribbon cable will be twisted, you have to untwist it and since it will only work when inserted in the chip with 1 side up it will have to go over the chip, it's a tight fit, but it will work. For further info see Sega Xtreme. Note, the porblem he speaks about at the end has never occured for me and I did basically exactly what he did. Lastly, I bought my chip from Jandaman.
